Prostate cancer is increasingly looking like an infectious disease, and may be sexually transmitted Mounting evidence suggests that prostate cancer is an infectious disease caused by a recently identified virus. The latest report, published today (September 7) in the Proceedings of the National Academy of Sciences, found the virus was associated especially with aggressive prostate cancers [. . .] The suspect is xenotropic murine leukemia-related virus (XMRV), a gammaretrovirus similar to viruses known to cause cancer in animals.A few people have attempted to use black-white differences in prostate cancer risk as evidence in favor of black-white differences in androgen exposure. This was always a backward and circular argument (prostate cancer researchers were responsible for the attempts to demonstrate higher androgen levels in black males in the first place). Various factors may contribute to elevated black prostate cancer risk (e.g., higher estrogen levels and genetic differences unrelated to androgen pathways), but this is probably a big one. Promiscuity is associated with prostate cancer in African-American men.
