Is prostate cancer genetically pre-disposed?

My father had prostate cancer at the age of 35 and two uncles on my father's side also had tumors quite young (before 50). I am currently 28 and my wife and I are considering having children. Is there any test I can take which will indicate whether I have a genetic pre-disposition to prostate cancer which I am likely to pass on to my children?

If there is also a strong family history of breast cancer in the female members of your family then the BRCA-2 gene test is worth taking. Otherwise, it would be sensible for you to have PSA screening from the age of 30 (a relaxed once two-yearly test throughout your 30's so long as the level remains low).
