Cancer In Singapore: A Comprehensive Resource Guide

While symptoms vary depending on the type of cancer, there are several “red flags” that should never be ignored. Common signs include unexplained weight loss, persistent fatigue that does not improve with rest, and the appearance of new, unusual lumps or thickening in areas such as the breast, underarms, or testicles. You should also monitor for changes in bowel or bladder habits, a cough that lasts longer than three weeks, or moles that change in shape, size, or colour. Because these symptoms can often mimic less serious conditions, it is vital to consult a General Practitioner (GP) if any abnormality persists for more than a fortnight.

While not all cancers are preventable, you can significantly reduce your risk through evidence-based lifestyle choices. Avoiding tobacco in all forms is the single most impactful step you can take. Maintaining a healthy body mass index (BMI) through a diet rich in wholegrains, vegetables, and fruits—while limiting processed meats and alcohol—is also crucial. In the Singapore context, protecting your skin from excessive ultraviolet (UV) radiation and staying up to date with vaccinations, such as the Human Papillomavirus (HPV) vaccine for cervical cancer and the Hepatitis B vaccine for liver cancer, are key preventive strategies.

The “best” screening method depends on your age, gender, and risk profile. For the general population, the most reliable approach is adhering to the national guidelines under Healthier SG. This includes regular mammograms for women over 50, HPV testing for women over 30, and annual Faecal Immunochemical Tests (FIT) for everyone over 50. For those seeking a more comprehensive overview, modern Multi-Cancer Early Detection (MCED) blood tests can now screen for dozens of cancer signals simultaneously. However, these should complement, rather than replace, established screening programmes like colonoscopies or physical examinations.

If you suspect you have cancer or have received an abnormal screening result, your first point of contact should generally be a diagnostic specialist or a Surgical Oncologist. Surgeons are typically responsible for performing biopsies to confirm the malignancy and determine if the tumour can be physically removed. Once a diagnosis is confirmed, you will likely be referred to a Medical Oncologist, who coordinates systemic treatments like chemotherapy or immunotherapy. In Singapore’s private and public sectors, most patients are managed by a multidisciplinary team (MDT) where surgeons and oncologists work together to plan your treatment from the outset.

Seeking a second opinion is a standard and highly encouraged practice in oncology; most specialists expect and welcome it. A second opinion can provide peace of mind by confirming the initial diagnosis and staging. More importantly, different hospitals or specialists may offer access to different technologies—such as Proton Therapy versus traditional radiation—or different clinical trials and emerging drug therapies. Since cancer treatment is a significant physical and financial commitment, ensuring that your proposed treatment plan aligns with the latest international standards of care is a prudent step in your healthcare journey.
