The study as discussed in the above news report did not conclude there was a two-fold chance of melanoma caused by PCa or its treatment. There was a double hedge in the opposite conclusion: the increased incidence may not be entirely the result of greater medical scrutiny.
But yes, be vigilant and get a regular skin checks! Be aware that having a history of basal cell carcinoma does double your risk of melanoma.
Fair enough, I guess. I've been just as pedantic about
some studies before. Gratifying to pounce on overstated conclusions, isn't it? In any case, we agree on the advice to be vigilant about
I will say that in my case this was not
noticed due to any extra vigilance from my prostate cancer. In fact, that has never even been suggested by anyone
in any part of my cancer experience, ever, anywhere. I'm a sample of one, but I'll also add this has never
been brought up in any
support group I've ever been in.
Personally (and yes, anecdotally) I'm inclined to skepticism if one pooh-poohs this as just finding it more because they look for it. I really don't think that's happening to any significant degree. I think the study authors were being careful. I'll also agree that is appropriate since they really didn't find a proven causal factor, merely a correlation. And we do know correlation without causality proves very little.
And Hal, yeah, I have the spectrum of fair skin, blue eyes, reddish blonde hair. I also a severe blistering sunburn on my back when I was 19, from a day snorkeling in Cuba.
In any case, here is the full quote from the investigator's conclusion:Based on two large, well-established, long-term cohorts, we suggest an association between a diagnosis of [prostate cancer] and risk of subsequent melanoma in white men, which may not be entirely a result of greater medical scrutiny. We postulated a potential role for androgens in the etiology of melanoma, which might contribute to the observed association. Pending biologic investigation, further understanding of the mechanisms that mediate the associations could eventually lead to elucidation of new targets for interventions that may modulate their incidence or activity…. Our finding of [prostate cancer] diagnosis as a risk predictor for melanoma holds general public health significance, which may inform clinical practice to address the queries and aid the care of patients with [prostate cancer].
