Colorectal Cancer
in Singapore

Colorectal cancer is the cancer of the large intestine. It is currently the most common cancer in Singapore and the incidence is still increasing at alarming rate. There are approximately 1500 new cases of colon cancer and rectal cancer in Singapore every year, affecting mainly people more than 50 years of age. Screening for colorectal cancer is the most effective way of prevention of this disease. Though the exact cause of colon and rectal cancer is still unknown, it can be attributed to the appearance of small growths in the lining of the large intestine called polyps. These colon and rectal polyps take more than 3 to 5 years to become cancerous. Prevention of colon and rectal cancer can be achieved if these polyps are detected early and removed.
