At what age is it usually common? Is it more in men or women? What are the symptoms?

Colorectal cancer (CRC) is a common and lethal disease. The risk of developing CRC is influenced by both environmental and genetic factors.

Approximately 145,290 new cases of large bowel cancer are diagnosed each year in the United States, of which 104,950 are colon and the remainder rectal cancers.

In 2005, more than 56,000 Americans will die of CRC, accounting for approximately 10% of all cancer deaths. In the United States, CRC ranks second to lung cancer as a cause of cancer death, and it is third both in frequency and cause of cancer death, in men and women separately.

Age is a major risk factor for sporadic CRC. It is a rare diagnosis before the age of 40, the incidence begins to increase significantly between the ages of 40 and 50, and age-specific incidence rates increase in each succeeding decade thereafter.

The lifetime incidence of CRC in patients at average risk is about 5%, with 90% of cases occurring after age 50. The incidence is higher in patients with specific inherited conditions that predispose them to the development of CRC.

Environmental and genetic factors can increase the likelihood of developing CRC. Although inherited susceptibility results in the most striking increases in risk, the majority of CRCs are sporadic rather than familial. At least some data supports the view that family history (as well as physical activity level) are stronger contributors to colon cancer as opposed to rectal cancer risk.

Associated risk factors:
1. Familial adenomatous polyposis
2. Hereditary nonpolyposis colorectal cancer
3. Personal or family history of sporadic cancers or adenomatous polyps
4. Inflammatory bowel disease
5. Diabetes mellitus and insulin resistance
6. Alcohol
7. Cigarette smoking

Hope this helped ;)
