Singapore is recognised as one of the safest countries in the world and has been holding that record for a long time. The nation topped the list for Gallup’s Global Law and Order Index for the year 2019, with an index score of 97 out of a possible 100. The Singapore Government has always been staying on top of all issues concerning the safety and security of the people.
With the ongoing COVID-19 situation, Singapore had shifted its Disease Outbreak Response System Condition (DORSCON) level from yellow to orange on Friday, 7 February. With the nation stepping up efforts to protect its citizens and businesses while fighting the spread of the virus, OpenGov looks to understand the measures taken by government agencies to handle such situations.
OpenGov had the opportunity to sit with Dr Lee Fook Kay, Chief Scientist at the Ministry of Home Affairs (MHA), to obtain more insights into how MHA is harnessing science and technology (S&T) in viable and innovative ways to ensure that it is at the forefront of safety and security efforts.
Dr Lee was appointed as the first Chief Scientist of MHA in April 2019. Prior to his appointment as Chief Scientist and since 2008, Dr Lee Fook Kay had been the Chief Science and Technology Officer at MHA.
In that role, he steered and led MHA’s development efforts in CBRNE (chemical, biological, radiological, nuclear and high-yield explosives), Forensics, Video Analytics, Biometrics, Profiling, Robotics, Automation, Artificial Intelligence and Human Factors, amongst others.
In particular, Dr Lee has had more than twenty years of experience in the CBRNE domain and has been instrumental in the strategic building and development of CBRNE capabilities in Singapore.
Today, he remains a key advisor in the National Advisory Board that oversees the strategic and policy issues in CBRNE. Dr Lee was also appointed as Singapore’s expert member in the IAEA Emergency Preparedness and Response Expert Group (EPREG) from 2012-2015.
Singapore’s technological capabilities for safety and security
Dr Lee strongly believes that the Home Team is well-positioned in terms of its technological readiness and that it has the zest to develop cutting edge technologies, for the Home Team is in the heart of each of its scientists and engineers.
Dr Lee said that one of MHA’s strongest capabilities is its laboratory network within Singapore, which can analyse an entire range of security-sensitive materials (SSM). This includes CBRNE and narcotics. This is particularly useful at Singapore’s border checkpoints, where analyses can be quickly conducted to determine if SSM is being smuggled into the country, during detection of suspicious activities. Dr Lee believes that this capability is the first of its kind in the world.
Importance of taking citizens’ needs into consideration for technology development
Dr Lee noted that technology development efforts, in the safety and security arena, were previously tended to emphasise improvements in systems, over human performance. Besides looking at improving the human operation of machines, it is imperative for the Home Team to go one step further: Taking citizens’ needs into consideration. “We need the citizens, whom we are aiming to protect, to accept the technology serving them and use it,” said Dr Lee.
Dr Lee shared examples of such technologies being currently developed on. A prototype for an automated car clearance system, at the land checkpoints, is being trialled with passenger cars coming through. The user-friendliness and experiences of those going through the checkpoints by car are being assessed as well. An exoskeleton is also being developed for SCDF’s firefighters. A key consideration of this technology is that while it is primarily meant to protect the firefighters wearing it during their line of duty, the exoskeleton should also not inadvertently cause injuries to those whom the firefighters are trying to save.
Regarding the possibility of pushback from citizens on the introduction of new technologies, Dr Lee pointed out that where practical, feedback is collected from the public. For example, when new technologies are being tested at checkpoints, the public trying them out are also interviewed and asked for their feedback on the technologies.
MHA labs countering bioterrorism and virus outbreaks with science and technology
The threats of bioterrorism and virus outbreaks are becoming ever real, such as in the case of the ongoing COVID-19 crisis, and countries are stepping up efforts to protect their citizens.
The Home Team CBRNE network of laboratories are located at Singapore’s land and sea checkpoints, to detect and analyse suspicious incoming items into Singapore. The laboratories, therefore, need to be able to detect any items that contain hazardous materials and also be on the lookout for major bioterrorism agents, such as anthrax.
Dr Lee noted that the CBRNE laboratories are well-equipped to receive and process such suspicious items and ensure that any hazardous substances could be detected and contained. He also said that it is critical that the staff receiving these samples are well protected from such hazardous materials. Laboratory officers use gloves with filters, such as chemical filters or hyper filters, as well as filters which have a protective capability against radiation.
Prof. Zhang Li from CUHK’s Mechanical and Automation Engineering Department has created multi-functional small machines using three wetting traits of ferrofluids. These machines not only show improved deformation abilities but also offer various motion modes, expanding possibilities for miniature soft machines in biomedical applications.
The results of the research were published in Nature Communications and highlighted on its “Applied physics and mathematics” Editor’s Highlights site.
Amoeba-inspired soft machines that can change shape dramatically, split and join, have the potential for real-world use. These systems show promise for biomedical applications such as targeted drug delivery, minimally invasive surgery, cell transplantation, and medical catheters.
Utilising ferrofluid soft machines
Small magnetic soft machines are commonly made by combining hard magnetic particles with soft matter like hydrogels. However, their limited ability to deform makes it hard for them to move through narrow spaces like small lumens that have openings smaller or equal to the machine’s size. Thus, there is a need to discover new materials for building miniature soft machines with improved capabilities.
Prof. Zhang collaborated with Prof. Carmel Majidi from Carnegie Mellon University to create diverse soft machines using the three wetting properties of ferrofluids and their ability to change shape. These machines can perform multiple functions.
Ferrofluid is a liquid composed of tiny ferromagnetic/ferrimagnetic particles suspended in a fluid. In low-wetting states, a magnetic field can control the ferrofluid’s movement and shape, allowing it to perform various actions like stretching, jumping, rotating, tumbling, kayaking, wobbling, splitting, merging, and adapting to complex terrain. Ferrofluid droplets can also be transformed into liquid capsules to transport cargo through narrow passages like bile ducts.
Advantages of constructing small soft machines using various wetting traits of ferrofluids
Ferrofluid droplets in a high-wetting state can serve as arrays of artificial liquid cilia and move rhythmically like microbial cilia under the influence of an external magnetic field. This makes it possible to control the transport of biological fluids, like pumping blood. In a total wetting state, the droplets can form artificial liquid skins and adhere to inanimate surfaces, giving them the ability to control these objects.
The research team will concentrate on controlling substrate-wetting to switch between adsorption and detachment of ferrofluid “skin.” The use of stimulus-responsive fluids in soft machines enhances functionality and adaptability and opens new opportunities for the creation of miniature smart soft robots.

Nanoscience and nanotechnology deal with the study of nanoparticles and devices used across various scientific fields such as chemistry, biomedicine, mechanics, and materials science. The nanotechnology market covers the manufacture and use of physical, chemical, and biological systems and devices, ranging in scale from individual atoms or molecules to 100 nanometers.
Automated elections are cost-effective because they can accommodate up to 1,000 voters per clustered precinct instead of 500 voters per precinct in manual ballots, necessitating paying more workers. Therefore, Rep. Elpidio Barzaga Jr. of Cavite 4th District advised his colleagues in the House of Representatives to employ the Automated Elections System (AES) in the Barangay (village) and local council Sangguniang Kabataan (BSK) elections on October 30 this year.
In House Resolution 717, which he submitted on Wednesday, Barzaga asked the House Committee on Suffrage and Electoral Reforms to launch an investigation into the Electoral Reform Act. The viability and feasibility of executing automated BSK polls are discussed.
“It will not only result in faster outcomes and the announcement of victors, but it will also eliminate human involvement or error and confusion in the evaluation of ballots on an experimental basis on the BSK Elections in major barangays, ideally in Metro Manila,” he convinced.
There are 42,022 barangays in the country as of October 2022, each with one punong barangay (local official) and seven Sangguniang Barangay (village council) members, one SK chairperson and seven representatives.
There will be two polls for the BSK elections, one for ordinary voters aged 18 and above and another for SK electors aged 15 to 30. The lawmakers suggested repurposing and adjusting the existing Vote Counting Machines (VCMs) to accept two ballots from registered voters. Then, the devices can independently summarise the Barangay and SK elections’ scores.
The BSKE, scheduled for October this year, will use a manual election system in which voters will write the names of candidates on ballots. Historically, manual elections can encounter issues such as imprecise counting, perception, and appreciation of votes. The integration of votes in larger Barangays usually takes two to three days, as opposed to automated elections, which immediately transmit the results to the canvassing centre upon closing of the voting.
Barzaga stated that the Commission on Elections (Comelec) was praised for conducting the national and municipal polls on May 9, 2022, for having the fastest results and largest voter turnout since the Philippines adopted the AES in 2010, and that the public has accepted the outcomes of the elections. The 2022 national and municipal elections were attended by 55,290,821, or 84.10 per cent of the 67,745,526 registered voters.
The resolution also said that the Comelec owned the 97,000 reconditioned vote-counting machines (VCMs) it purchased in 2016 and leased more VCMs for the 2022 elections and that a portion of these machines will be used in the BSK Elections in the pilot barangays. Barzaga believes voters are well-versed in using AES since The Philippines have used the technology in the national and municipal elections in 2010, 2013, 2016, 2019, and 2022.
Meanwhile, the Commission on Elections (Comelec) has indicated that it is open to holding automated village votes. Comelec chairperson George Erwin Garcia noted that they would investigate the possibility of executing a pilot test of barangay and SK election automation in specific areas/precincts. He mentioned that Barzaga contacted him about the proposition earlier this week.
President Ferdinand R. Marcos Jr. signed Republic Act 11935 on October 10, 2022, rescheduling December 5, 2022, BSK elections to October 30, 2023, and holding other polls every three years after that. Meanwhile, earlier this month, OFW Party List Rep. Marissa Magsino suggested that the government should change the existing law to increase voting options to prevent voter disenfranchisement of about 1.83 million OFWs exercising their right to vote. The proposed legislation would enable Filipino personnel working abroad to vote via email, web-based portals, and other internet-based technologies.
All organisations that use alphanumeric Sender IDs to send SMS are now required to register with the Singapore SMS Sender ID Registry (SSIR) as part of the measures announced by the Infocomm Media Development Authority (IMDA) last October. This registration is intended to protect consumers from non-registered SMS that may be scams, a press statement has said.
Starting from 31 January, any non-registered SMS will be labelled as “Likely-SCAM”. This functions similarly to a spam filter or spam bin. Consumers might get non-registered SMS labelled as “Likely-SCAM” and are advised to exercise caution. If unsure, consumers are encouraged to check with family and friends. This will improve IMDA’s overall resilience against scams.
All organisations that use alphanumeric Sender IDs must register early with the SSIR. This is to give adequate time as non-registered SMS Sender IDs after 31 January will be labelled as “Likely-SCAM”. Organisations that have not registered their Sender IDs are advised to do so, the statement said.
As of January 2023, over 1,200 organisations have already registered with SSIR, using more than 2,600 SMS Sender IDs. These include financial institutions, e-commerce operators, logistics providers, and SMEs that send SMS to their customers who have registered with the SSIR.
In recent months, IMDA reached out to organisations through aggregators and associations such as the Singapore Business Federation, Singapore International Chamber of Commerce, and Association of Banks in Singapore, to encourage them to register with the SSIR. The mandatory SSIR regime is part of a broader effort to protect against scams, which also includes working with telecom operators to reduce the number of scam calls and SMS coming through the communication networks.
Since the implementation of the SSIR in March 2022, there has been a significant decrease in scams reported through SMS, with a 64% reduction from the last quarter of 2021 to the second quarter of 2022. Additionally, scam cases perpetrated via SMS dropped from 10% in 2021 to 8% in Q2 2022, down from 10% in 2021.
To effectively combat scams, a collective effort from society is needed. Despite implementing various measures, scammers may adapt their methods and tactics. IMDA will continue to collaborate with other stakeholders in the fight against scams, but individual vigilance and awareness are crucial. Consumers should remain vigilant and share scam prevention tips with friends and loved ones, the statement said.
IMDA leads Singapore’s digital transformation with infocomm media. To do this, IMDA is working to develop a dynamic digital economy and a cohesive digital society, driven by an exceptional infocomm media (ICM) ecosystem. It fosters talent, strengthens business capabilities, and enhances Singapore’s ICM infrastructure. IMDA also regulates the telecommunications and media sectors to safeguard consumer interests while fostering a pro-business environment and enhances Singapore’s data protection regime through the Personal Data Protection Commission.
Scams and unwanted commercial electronic messages and calls are an international problem with scammers continuing to prey on unsuspecting parties. Last year, IMDA and Australian Communications and Media Authority (ACMA) signed a Memorandum of Understanding to boost cooperation and fight scams and spam. The agreement covers cooperation in information sharing and assistance in investigations relating to scam and spam calls and short message services. The two sides also agreed to mutual exchanges of knowledge and expertise and collaboration on technical and commercially viable solutions in relation to scam and spam communications.
A partner company of the Hong Kong Science and Technology Parks Corporation (HKSTP) unveiled “ARIA-diabetes risks”, a retinal imaging tool for non-invasive pre-screening of diabetes. This solution aims to tackle the problem of millions of undiagnosed diabetes patients worldwide.
The International Diabetes Federation reports that in 2021, nearly half of all adults with diabetes were unaware of their condition, amounting to 239.7 million individuals worldwide. In Hong Kong alone, at least 600,000 individuals have diabetes and more than 110 million in mainland China. This is a significant issue that has both local and global implications, as people with diabetes are at an increased risk for serious and potentially life-threatening complications such as heart disease, kidney disease, and vision loss.
The Automatic Retinal Image Analysis (ARIA) technology uses artificial intelligence and machine-learning techniques to detect various health issues. The solution provides a non-invasive pre-screening tool for diabetes that delivers results within minutes and has an accuracy rate of over 90%. It does not require a blood test and offers a faster and more accessible way for early diabetes diagnosis.
The partner company formed a joint venture called “Oneness Health” with an HKSTP incubatee to capitalise on the potential for remote healthcare offered by the ARIA-diabetes risks solution.
The joint venture combines the partner company’s retinal analysis technology with the incubatee’s network of Traditional Chinese Medicine (TCM) practitioners, as well as their software and hardware development capabilities. This creates a one-stop service platform under the name “Oneness Health” that provides high-risk patients seeking TCM treatment with added convenience and flexibility, with the goal of “disease prevention”.
The Oneness Health platform will offer features such as online appointments, mobile assessments, diagnosis, and personal health management in the first quarter of 2023.
In the near future, it will also provide prescriptions for traditional Chinese medicines that can be dispensed through auto-dispensing machines at over 100 convenient locations in 18 districts of Hong Kong or collected at various NGO centres. Additionally, door-to-door courier service will be available for single elderly individuals or needy families.
The CEO of HKSTP stated that the Park is dedicated to promoting innovation by providing a comprehensive support system for translational research, product development, and commercialization. The ARIA-diabetes risks solution from the two firms which is now being offered under the Oneness Health platform is a prime example of how innovative solutions can be developed in Hong Kong and at the Science Park.
The combination of breakthrough science, world-first technology, advanced software, and hardware to create an innovative primary healthcare delivery platform through Oneness Health, is a testament to the speed, talent, infrastructure, and innovation capability of Hong Kong’s I&T ecosystem.
In line with the HKSAR Government’s Primary Healthcare Blueprint announced in December 2022, the Oneness Health platform will contribute to the government’s goal of establishing a more community-based primary healthcare system. The platform will significantly improve healthcare convenience, expand treatment options, lower patient costs, and alleviate the burden on Hong Kong’s hospitals and clinics.
The Blueprint sets out a strategy road map towards establishing a primary healthcare system that can improve the overall health and quality of life for popular in a stable manner, under the challenges brought on by an ageing popular and increasing chronic disease prevalence.
Budi Gunadi Sadikin, Minister of Health, announced the development of SATUSEHAT, an interoperable Indonesian health data system. Budi aimed to complete the digitalisation of health data by January 2024. In keeping with the spirit of an impactful bureaucracy, the Minister of Health is sure Indonesians would benefit from digitisation.
“The concept is interchangeable; (health facilities) can use the information anywhere: all hospitals, both public and private, pharmacies, clinics, health centres, and labs throughout Indonesia will use the same data format, and (the data) can be exchanged,” he said at the launch of the Digital Transformation Office (DTO) Space in Jakarta.
SATUSEHAT is a health platform that serves as a forum for various health apps from companies in the health business. As a result, all applications and health service facilities on the SATUSEHAT platform, including vertical hospitals, government hospitals, private hospitals, health centres, Posyandu, laboratories, clinics, and pharmacies, must adhere to the Ministry of Health’s criteria.
People no longer need to carry physical medical record files while moving hospitals because of this platform. All patient medical record resumes have been digitally captured on the SATUSEHAT platform, which can be viewed from anywhere and at any time using mobile phones.
“For certain users who haven’t been able to produce health applications, we can aid later. (And) We can eventually give standard and free applications for significant stakeholders such as Puskesmas (community health centres) and Posyandu (toddler integrated service post). This way, we can do data integration elegantly on the same platform,” Budi confirmed.
Furthermore, the Ministry of Health established DTO as a Ministry of Health work unit dedicated to implementing the Healthy Indonesia programme by developing effective data-driven policies and digital technology products. User-Based Technology Development, National Health Data Integration, Technology Capacity Building, and Data-Based Policy Making are the four principles of digital transformation being implemented.
Budi directed the DTO and the Data and Information Centre (Pusdatin) to take meaningful actions to expedite national health data digitisation. DTO must complete nationwide health interoperability that is transparent and accessible to all parties. The merger process started on July 6, 2022, and is expected to be finished by the end of 2023.
Another challenge is to combine clinical and genomic data to assess the health of the Indonesian population deployed with Artificial Intelligence to create more detailed and exact results. AI will subsequently support the Ministry of Health’s clinical and genomic data. The services are designed to help Indonesia advance health biotechnology.
During the inauguration ceremony, the Minister for Administrative Reform and Bureaucratic Reform (PANRB), Abdullah Azwar Anas, praised the Ministry of Health’s digital transformation in the healthcare system. He anticipated that the shift would affect at least five items. First and foremost, it increases the quality of healthcare services. Second, it improves access to healthcare services. Third, raise the added value of the health sector economy with a focus on domestic goods.
Fourth, speeding the achievement of the government’s main healthcare projects, such as lowering stunting prevalence. Fifth, strengthen health human resource expertise while guaranteeing equitable distribution across the country.
“For example, we may ensure that a health concern is treated by integrating data, then monitoring therapy until the assessment is entirely digitally driven. We can learn from the Covid-19 pandemic, in which health technology was extremely useful in combating the pandemic,” he went on to say.
Anas believes that the Ministry of Health’s SATUSEHAT will soon be merged with the National Electronic-Based Government System. He praised the tremendous efforts made by the Ministry of Health to implement digital transformation.
The Ministry of Health’s consolidation initiative can serve as a model for other Ministries/Institutions looking to increase work units’ roles in supervising the government’s digitalisation activities. Anas is optimistic that the integrated ecosystem of digital health data will be a huge step forward for the country’s health sector.
Thailand’s Minister of Digital Economy and Society (DES), Chaiwut Thanakmanusorn, disclosed that the Cabinet adopted the Royal Decree Measures for Prevention and Suppression of Technology Crime in principle. Accordingly, the act was assigned to the Office of the Council of State for consideration before further enforcement.
In essence, the proposed order prescribes steps to prevent and suppress deceit in people transferring money by telephone or other means. The law also grants authorities the authority to regulate financial transactions. It prohibits opening accounts on electronic cards or wallets to bring money or property to be used in criminal acts.
The proposed Decree requires financial institutions and business operators to disclose information about their client’s accounts and transactions via a data exchange system to suspend transactions when necessary.
“The drafting of this law is a collaboration of several agencies, including the Royal Thai Police, the NBTC Office, and the Bank of Thailand. Thai Bankers Association Anti-Money Laundering Office (AMLO), etc., believe that this regulation will undoubtedly assist in eliminating the problem of ghost sims, pony accounts, and online crime problems,” Chaiwut clarified.
Procedures for halting transactions can be done when a financial institution or business operator discovers a questionable issue or is told by a competent official. They must advise financial institutions or business owners to halt transactions. The transmitting financial institution or company operator must promptly halt future transactions. They can comply with the transaction if they inspect and find no suspicious cause.
If the victim reports a fraudulent transaction, financial institutions or business operators must immediately and temporarily cease transactions and tell financial institutions or business operators receiving transfers to do the same. For the victim to file a complaint with the investigators within 48 hours, the investigators must act on that account and electronic wallet within seven days of notification. Notification of information or evidence can be sent by phone or electronically.
Furthermore, Telecommunication Service Providers have the authority to communicate information and allow the Royal Thai Police, AMLO offices, and approved agencies to view the information exchanged. At the same time, the Office of the NBTC is in charge of developing the central database for user registration information, short messages, investigation, and prevention.
The use or disclosure of personal data to prevent, detect, and deter online crime will follow personal data protection legislation. It is required to properly tackle the social media problem of fraudulent people and eliminate some legal issues that cause the integration of work between multiple agencies to be stopped or delayed in the current situation.
The act governs the usage of an account and a SIM card. It will instruct consumers to create a personal account for an electronic card or wallet. The act of opening a without the purpose of using it will be considered an infringement. Anyone who knowingly or ought to knowingly allow another individual to use or borrow their SIM card is breaking the law since criminals could use it for fraud or illegal conduct. Breaches of this law may be imprisonment for up to three years or a fine of up to 300,000 baht (US$9163.10) or both.
It is illegal for anybody to obtain, market, or post news to purchase or sell accounts, electronic cards, electronic wallets, or phone sim cards that may result in criminal activity. Anyone who breaches this will face imprisonment for 2 to 5 years and a fine ranging from 200,000 baht (US$9163.1) to 500,000 baht (US$15271.84) or both.
When aberrant behaviour is discovered or a complaint is made to the bank and enables banks and relevant organisations to reveal and exchange information about online crimes through a standard database system. Thai authorities have the authority to suspend or postpone financial transactions for an extended length of time.
Special Wisit Wisitsorn-at, Professor, the Permanent Secretary of the Ministry of Digital Economy and Society, expressed the MDES need to present the draft to the Office of the Council of State for review and consideration before the announcement goes into effect.
Sybill, an artificial intelligence tool, has been developed to estimate the risk of lung cancer. Lung cancer is the world’s deadliest cancer, accounting for 1.7 million fatalities in 2020, killing more people than the following three deadliest cancers combined. Consequently, it is critical to have an early detection solution to provide immediate treatment.
Cancer early identification AI tools can result in a better long-term outcome, according to MIT’s Abdul Latif Jameel Clinic for Machine Learning in Health, Mass General Cancer Centre (MGCC), and Chang Gung Memorial Hospital (CGMH). When it’s advanced, the five-year survival rate for the lung cancer patient is closer to 70%, compared to 10% when it’s early.
“It’s the worst cancer because it’s so common and so difficult to treat, especially once it’s advanced,” explained Florian Fintelmann, MGCC Thoracic Interventional Radiologist and Co-author of the current study.
Today’s images of the lung computed tomography (LDCT) procedure is presently the most common way people are checked for lung cancer to detect it early enough to be surgically removed. But Sybill takes the screening a step further in comparison to LDCT. It can forecast the likelihood of a patient acquiring lung cancer within six years by analysing LDCT imaging data without the intervention of a radiologist.
Co-author Peter Mikhael, an MIT PhD student in electrical engineering and computer science and an affiliate of Jameel Clinic and the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), associated the procedure with “trying to identify a needle in a haystack”. However, Sybill successfully detects early-stage cancer with satisfactory results, as shown in a new article published in the Journal of Clinical Oncology.
Fintelmann and his team labelled hundreds of CT scans with evident cancerous tumours that would be used to train Sybil before testing the model on CT scans with no discernible evidence of disease. The researchers took precautionary measures to ensure Sybil’s ability to identify cancer risk appropriately.
Sybil achieved C-indices of 0.75, 0.81, and 0.80 using a heterogeneous group of lung LDCT scans gathered from the National Lung Cancer Screening Trial (NLST), Mass General Hospital (MGH), and CGMH over six years. Models with a C-index score of more than 0.7 are regarded as good and models greater than 0.8 are considered strong, with 1.00 being the maximum attainable score. The ROC-AUCs for Sybil’s one-year prediction were considerably higher, ranging from 0.86 to 0.94.
Jeremy Wohlwend, an MIT electrical engineering and computer science PhD student and Jameel Clinic and CSAIL collaborator, was shocked by Sybil’s excellent score despite the absence of apparent disease. “We discovered that even while we [as humans] couldn’t see where the cancer was, the model could still predict which lung would eventually get cancer,” he described. “It was incredibly interesting that [Sybil] could identify which side was the more likely side.”
The 3D aspect of lung CT scans made Sybil challenging to create. Because early-stage lung cancer covers minuscule areas of the lung. It is just a fraction of the hundreds of thousands of pixels that make up each CT scan. The radiology data used to train Sybil was essentially free of any indicators of malignancy. Lung nodules are denser areas of lung tissue that, while they have the potential to be malignant, are most of the time not and can be caused by healed infections or airborne irritants.
In the United State, many patients diagnosed with lung cancer today have never smoked or are former smokers who quit more than 15 years ago – characteristics that preclude both groups from receiving lung cancer CT screening in the United States. However, cancer can affect a young, healthy, and athletic individual. As a result, prevention is vital to saving more lives.
