that is very curious. My dad fathered 3 daughters.

Y Chromosome May Have Role in Prostate Cancer

Y Chromosome May Have Role in Prostate CancerNEW YORK JAN 02, 2007 (Reuters Health) - The Y chromosome may beinvolved in prostate cancer, suggest findings of an Israeli study inwhich fathers with only daughters had a higher risk of prostate cancerthan did fathers with at least one son."Overall, our findings are consistent with hypotheses that tie Ychromosome loci to prostate cancer, although other explanations cannotbe excluded," write Dr. Harlap of Columbia University, New York,and colleagues in the January 3rd issue of the Journal of the NationalCancer Institute.Among 38,934 fathers in a family-based research cohort who were followedfor up to 40 years after the birth of their children, 712 developedprostate cancer. Compared with men who had at least one son, men with only daughters hadan adjusted relative risk of prostate cancer of 1.40 (p < 0.0001).http://www.cancerpa ge.com/news/ article.asp? id=10462I do not understand why this happens. Feeling dense today. Can someoneexplain please.Kathy__________________________________________________

My dad supports this theory since he had 3 daughters, no sons.

But then my dad had three sons, one daughter last. Died at age 68 from

PCa. And I have two sons, diagnosed at age 57 with PCa. Some of these

studies are pretty inconclusive in some cases. Considering all the

prostate cancer there is, shouldn't be too difficult to come up with a

more in-depth study on this. I've always wondered myself about dairy

products? But then my dad didn't drink a whole lot of milk as I do.
