At what age should you start prostate cancer screenings if you have a strong family history

At what age should you start prostate cancer screenings if you have a strong family history?
My husband will be 30 soon and I wonder when he should start psa screening for prostate cancer. His father, paternal grandfather, and paternal uncle all had/have prostate cancer. His father was diagnosed at age 43 but it appears to be out of remission now after 10 years.

I've read the recommended age is 45 or 50 yrs but if my father-in-law waited to 45 he'd be dead by now. So if you have a strong family history, what's the best time to start?

Hello Bargain Mom: If your husband has a strong family history of prostate cancer he should go in starting at age 25 for blood work also to learn from his doctor what to do to avoid getting it as well as a base line screening from his doctor. But since he is over 25 now would be a good time to get checked out they will do blood work as well as a yearly physical. The best way is to get a full check up every year if you have a family history of cancer.
