Colorectal cancer is the third leading cause of cancer-related deaths in Malaysia, despite being highly treatable, especially when caught early. It is the most common cancer after breast cancer, affecting around 19 out of 100,000 Malaysian men and 14 per 100,000 women. The disease begins as benign polyps in the colon or rectum, which can become cancerous over time. Early detection is key, but symptoms often appear in advanced stages, making diagnosis challenging. Risk factors include age, diet, smoking, obesity, and genetic mutations. Screening methods like colonoscopy are crucial for early identification, and treatment options range from surgery to chemotherapy. Preventative measures include a healthy diet, regular exercise, and avoiding tobacco and excessive alcohol.
