==Overview==
Many times, doctors do not know what the direct cause of colon cancer is. The cancer develops as it does with many other forms of cancer.  Healthy, normally dividing cells of colon begin to continue dividing even when new cells are not needed.  These growths from the new cells can become cancerous over time.
The cause of colorectal cancer has not been identified. To review risk factors for the development of colorectal cancer, [[Colorectal cancer risk factors|click here]].

*[[Polyps]]
The cause of colorectal cancer has not been identified. However, there are certain risk factors that predisposes to risk of CRC.
**These are [[pre-cancerous]] cells that can appear mushroom shaped. It is important to have polyps removed before they have a chance to become [[cancerous]]


*[[Hereditary nonpolyposis colorectal cancer]] ([[HNPCC]])
To review risk factors for the development of colorectal cancer, [[Colorectal cancer risk factors|click here]].
**HNPCC can cause the development of colon cancer before the age of 50.
**Increases risk of other [[cancers]] not just colon cancer.
**It can be detected by [[genetic testing]].
 
*[[Familial adenomatous polyposis]] ([[FAP]])
**It is rare.
**It causes there to be many [[polyps]] growing on the lining of the [[colon]] and [[rectum]].
**[[Polyps]] can develop into [[cancers]].
 
*[[Smoking]]
**There is a controversial link between smoking and colon cancer.
**Studies have shown that smoking does cause the likelihood of the development of [[colorectal]] polyps doubles. <ref name="pmid19088354">{{cite journal |author=Botteri E, Iodice S, Bagnardi V, Raimondi S, Lowenfels AB, Maisonneuve P |title=Smoking and colorectal cancer: a meta-analysis |journal=[[JAMA : the Journal of the American Medical Association]] |volume=300 |issue=23 |pages=2765–78 |year=2008 |month=December |pmid=19088354 |doi=10.1001/jama.2008.839 |url=http://jama.ama-assn.org/cgi/pmidlookup?view=long&pmid=19088354 |accessdate=2011-12-12}}</ref>

***In 100,000 smokers,there were 65.5 cases of colon cancer
***In 100,000 non smokers, there were 54.7 cases.
