In men, newly discovered cancers are often in the prostate, lungs, and colon. In women, they're usually in the breast, lungs, and colon. Lung and prostate cancer are the leading causes of death in men, while lung and breast cancer top the list for women. In Vietnam, liver cancer rates are particularly high in men due to alcohol consumption and the complex nature of hepatitis B infection. To prevent cancer, important screening tests include low-dose lung CT scans, mammography combined with breast ultrasound, colonoscopy, and abdominal ultrasound with AFP and PSA blood tests. The most important factor remains a healthy diet and lifestyle. Eat well, exercise regularly, and protect and strengthen your immune system. Quit smoking and alcohol to safeguard your health.
