I like to do my fair share of running, and found his comment on "marathon runners" having a suspiciously high cancer rate. Curious and wanting to know more... Granted I have only skimmed over the following ( ie this stuff is hot off the internet press ) http://cebp.aacrjournals.org/content/17/1/183.full http://cebp.aacrjournals.org/content/17/1/183.full This is a full text article discussing how regular exercise whici I consider running and marathon training to be part of, is useful in the fight against colon cancer, yet they are not 100% sure why. http://jnci.oxfordjournals.org/cgi/content/full/96/24/1805 http://jnci.oxfordjournals.org/cgi/content/full/96/24/1805 Still getting my head around this article, yet it is a fascinating read. Marathon runners are at risk of skin cancer. http://www.ncbi.nlm.nih.gov/pubmed/17116838 http://www.ncbi.nlm.nih.gov/pubmed/17116838 http://archderm.highwire.org/cgi/content/abstract/142/11/1471 http://archderm.highwire.org/cgi/content/abstract/142/11/147... http://www.msnbc.msn.com/id/15817212/ http://www.msnbc.msn.com/id/15817212/ ( first found via msnbc, I wasn't happy with msnbc as my source ) If anyone else has more links on cancer linked to marathon running please add, as I would like to read more on it. As with anything on the internet, this article or the papers above, always read up from multiple sources and see what lies between the lines. My biggest problem with this essay, knowing it was part of a research paper, im saddened by his lack of citations.
