Colon Tumors

Causes of Colon Tumors

Colon cancer is the result of colorectal polyps that have become abnormal and grown out of control.  Some 90 percent of people with colon polyps or tumors are over the age of 50.

In addition to age and the presence of colorectal polyps, the following are risk factors for colon cancer:

  • Prior personal or family history of colorectal, breast or uterine cancer
  • Personal history of ulcerative colitis or Crohn’s disease
  • Smoking
  • Alcohol consumption
  • Obesity
  • Physical inactivity
