Well folks, the circus has come to town. Unfortunately, the subject of this spectacle is prostate cancer. If you haven’t been in a coma in the last few days you must have seen the headline:
SEX CAUSES CANCER!!
For me this is deja vu all over again. Some months ago I reported about a study which addressed this same issue and concluded that frequent “youthful” sex actually had a protective effect against prostate cancer. (See “Does Masturbation Cause Prostate Cancer?”, 4/23/08, http://prostatecancerblog.net/?s=promiscuity&x=16&y=10.) I expressed skepticism about those results and noted that I was aware of several older studies which had indeed found a positive correlation between *promiscuity* and prostate cancer.
I am not going to go into detail about the new study because I don’t find the results credible or useful. But I will give you a link to an excellent article in which a PC expert at the University of Chicago reviews the findings and puts them into perspective: “Link Between Sexual Activity and Increased Risk of Cancer Open to Question“, Medill Northwestern Report, Jan. 28, 2009.) https://web.archive.org/web/20090131121826/http://news.medill.northwestern.edu:80/chicago/news.aspx?id=113327. This is all you need to read.
Also, I came across an article about this in Salon magazine that was written by a doctor and is very good (and not surprisingly, the “Most Read” item on the page). http://open.salon.com/cover.php. Note: graphics are for adults only!
One problem with the data relied upon here is that it comes from men in their 60’s who were reporting on sexual behavior that occurred 30 years ago. I can tell you that memory does not get better with age, and I have a while to go before I reach 60.
Also, I am aware of a phenomenon that might be at work here which has eluded the researchers. I recently read that *some* men who’ve had PC and have been negatively affected sexually as a result have a tendency to aggrandize their pre-treatment sexual prowess (consciously or not), as a way of coping with the effects of ED or other bodily changes on self-esteem and identity. “Changed Men: The Embodied Impact of Prostate Cancer”, Qualitative Health Research, Vol. 19, No. 2, 151-163 (2009).
I must say it’s surprising how many men in the PC forums report having engaged in Olympic-level sexual athletics *before their surgery*. One man even says that he was a sexual “legend” in his own time!
My point is, I wouldn’t be surprised if some of the men with PC reported higher levels of youthful sexual activity than they actually engaged in, and of course this would bias the resu
