I was wondering if it's a good idea to start discussing with my doctor the checking of my PSA count now that I'm 35.

I suppose it can't hurt, although your doctor may say no and your insurance will probably not pay for the tests at your age. Usually, unless there is something in your history to suggest a higher risk of prostate cancer (for example, family history of prostate cancer, persistent urinary symptoms, being African American or partaking of a high fat diet), testing isn't necessary until you're older. Absent any higher risk factors, the Cleveland Clinic recommends screening with the digital rectal exam starting at age 45, with PSA blood tests to accompany the digital rectal exam starting at age 50. Unless you have a reason to have the tests, you would be better served to practice good prostate health by following a low fat diet, keeping in good physical shape, and enjoying lots of sex. There will be plenty of time to worry about all of that other stuff later. No one in a right state of mind would ask for needles and probing gloved fingers without a good reason.

There was an a study published in the Nov 1 issue of Journal of National Cancer Institute which suggests that men should have their PSA levels tested around 40 to use as comparison for future changes. They have found that rate at which man's PSA rises may be more important than setting an absolute level (such as 4.0) to identify men while disease is still curable.
