Re: What are the causes of colon cancer?
There are known and unknown causes of colon cancer. "There is a hereditary condition called FAP where a person develops hundreds of polyps in the colon at a young age. If a total colectomy (removal of entire colon) is not done, this condition leads to colon cancer.
Another source of colon cancer is a genetic condition called HNPCC - Hereditary Non-polyposal colon cancer; also called Lynch Syndrome. This is a genetic mutation that makes a person very likely (80% chance over a lifetime) of developing colon cancer, endometrial cancer (60%), ovarian cancer (12%) and other cancers associated with this syndrome. Not all of the mutations have been identified at this time, but since it is a dominant hereditary trait, there is a 50% chance of the person's parents, siblings or children will have the condition too.
Certain dietary habits, such as eating a lot of red or processed meats research studies have shown, may increase the risk of developing colon cancer. However, there are many people that develop colon cancer and follow a healthy diet, exercise, have no family history of cancer, but they get it anyway. We don't know the cause in those situations. Also, colon cancer is being diagnosed in younger people (20's, 30's) in increasing numbers. Again, no one knows why.
HNPCC (Lynch Syndrome)
2003 Stage 3 colon cancer
1995 Stage 1 endometrial cancer
