Colorectal Cancer is the most common cancer in Singapore 

Colorectal cancer is a cancer that arises in the large intestine or rectum. It is the most common cancer among men and second most common cancer among women.

Colorectal cancer can be prevented or effectively treated if diagnosed early. Some of the common symptoms include a change in bowel habits, blood in the stools or persistent abdominal pain.

Besides symptoms, what are the possible causes and risk factors? Is regular screening recommended? What are the types of treatments available for colorectal cancer?
