Only a very small number of prostate cancer cases are hereditary (about
5%, when a gene mutation is passed within a family from one generation to the next), but it frequently
seems like it is much more than that. And just because you have close relatives with PC doesn't mean that you are one of the rare cases...you probably aren't.
Prostate cancer is a ubiquitous disease where the most significant risk factor is age alone. Autopsy studies of men who died in accidents show that 50% of 50-year olds have it, 60% of 60-year olds have it, 70% of 70-year olds, etc. Many men here at this site are a product of our times—the “PSA-era”—where increased screening, increased rates of prostate biopsy, and increased sampling of the prostate during biopsy have created new levels of cancer “patients” with smaller-and-smaller amounts of PC found. Pre-PSA-era, the indolent prostate cancers were largely ignored as harmless (and they were).
Other studies have shown that if your brother or father were diagnosed with PC, you have a higher probability of increased diagnostic activity; the more rigorously one is screened/biopsied/etc, the more apt one is to be diagnosed.
Most prostate cancers, as with most organ cancers, are sporadic. Check out this Medscape article, if you want:
"Prostate Cancer in the Family: Risks Are Inflated". A Medscape subscript
ion is required, but it is free.
I wouldn't spend any energy thinking about
any family-tie...the relevance is very low, except what you can learn from their experiences.
