You’re at an increased chance of developing colon and rectal cancer if you’re over 60, eat a diet heavy on red and/or processed meats, and/or have other bowel diseases.
Colon cancer starts in glands in the lining of the colon and rectum, says the U.S. National Library of Medicine. Symptoms include abdominal pain or tenderness, blood in the stool, and diarrhea. The best test to detect colorectal cancer is a colonoscopy. There is a very good chance colorectal cancers can be cured if they are spotted early enough. Preventive measures include switching to a low-fat, high-fiber diet and getting a colonoscopy if you are 50 or older.
The Colon Cancer Alliance is committed to improving colon cancer awareness, education, and providing more life-saving screenings. Their biggest event is the traveling Undy 5000, a 5K run/race in which participants are encouraged to run in their boxers. As of January 2013, the race had raised almost $87,000 in support of the Alliance.
