Smokers Have Increased Risk of Colon Cancer

Feb. 7, 2011

When stratified for tumor location, the risk of proximal colon cancer was increased for former and current smokers, but the risks for cancers in the distal colon or rectum were not.

There has been consistent evidence for a relationship between smoking and colorectal cancer. However, it is not clear whether the colon or rectum is more sensitive to the effects of smoking. According to a study in Clinical Gastroenterology and Hepatology, current and former smokers have an increased risk of colon cancer, which appeared to be more pronounced in the proximal than the distal colon location.
