I'm hoping the research into prostate cancer will give us the equivalent of BRCA1 and BRCA2 alleles that are indicators of increased breast cancer risk so that only those with heightened risk for prostate cancer (like my family history of it) will have to get tested more frequently and younger. I think it was my human physiology professor (or maybe it was anatomy) that said it was something like 80-90% of men over the age of 75 have at the very least an englarged prostate, but at that point in their lives the treatment was more likely to kill them than the cancer.
