A member asked:

Is there a connection between colon cancer and prostate cancer?

A doctor has provided 1 answer

None: Colon cancer grows within the lumen of the bowel until a population of invasive cells spread to serosa and then nodes. It is probably secondary to a polyoma virus. Prostate Ca which is hormonally controlled probably arises from the MMTV virus entering the Wnt-1 gene to induce transformation. This same virus effects breast Ca and men married to women with Br Ca get more prostate Ca.
