Cancer is a disease in which cells in the body grow out of control. When cancer starts in the colon or rectum, it’s called Colon Rectal, or colon, cancer. Colon cancer and rectal cancer have many features in common. They are discussed together here except for the section about treatment, where they are discussed separately.
Colon Rectal cancer affects men and women of all racial and ethnic groups, and is most often found in people aged 50 years or older. In the United States, it is the third most common cancer for men and women.
Risk Factors For Colon Rectal Cancer –
A family history of colon cancer
Smoking and alcohol
Lack of physical activity
Diseases such as diabetes, inflammatory bowel diseases (Crohn’s and ulcerative colitis as examples), and obesity
Poor diet, including excessive amounts of red, processed meat
While some inherited genetic disorders can cause Colon Rectal cancer – including familial adenomatous polyposis and hereditary non-polyposis colon cancer – these represent less than 5% of all cases. These cases typically start as a benign tumor, often in the form of a polyp, which becomes cancerous over time.
