Can Colon and Rectal Cancers be Prevented?

Prevention and early detection are the key to controlling and curing these cancers. Colorectal cancer begins as polyps, which are small, benign (non-cancerous) growths of cells that form on the inner lining of the colon. These polyps may grow larger over time and become cancerous, which is why if any polyps are found, it is usually advisable to have them removed before they can become cancerous. Lifestyle changes can also reduce a person's chances of developing colon cancer. To reduce the risk of colon cancer, it is best to follow a diet that is low in fat and high in fruits, vegetables and fibre. It is also advisable to exercise regularly, to drink alcohol in moderation and for smokers to give up smoking.Oestrogen replacement therapy may reduce the risk of colon cancer in postmenopausal women. Use of contraceptives is also thought to protect against the development of colon and rectal cancer.
