Risk rises with age: Risk of colon cancer starts to rise significantly around age 45, and the risk continues to rise with every passing decade of life, though there is a hint that the rate of rise slows down in the ninth decade of life. If you have symptoms of colon cancer, though, you need medical attention no matter how young you are.

Unknown: Uncertain as to what exactly causes any cancer, which is non-stop cell growth. Some risks are genetic, some are related to obesity, eating too much fatty foods, eating too much meat and not enough fruits and fibers, cigarette smoking, etc.
