Colorectal Cancer

In Singapore, colorectal cancer is the top cancer in men and second in women, while breast cancer is the top cancer affecting women. This is followed by lung cancer – the second most common cancer in men and third most common in women. 

Colorectal Cancer 

This is also known as cancer of the colon and rectum – the last part of the gastrointestinal tract. When food enters the colon, water is absorbed and bacteria converts food residue into faeces. The rectum is where faeces are stored before being passed out through the anus. Polyps may form on the inner wall of the colon and rectum. However, some polyps may turn cancerous and should be removed if detected.
