The most cost-effective tool that we have today is the simple PSA blood test. However, I'd argue this is unnecessary at your age.

Agreed, prostate cancer is rare under age 40. 45 to 50 is a good age to get tested if there is no family history.

Other things:

- There is a very new multi-cancer blood test called Galleri that might catch it, but I think you have to be above age 50.

- You could potentially do genetic testing to look for markers but it's probably not worth the expense unless you have family history.

- There's also the old fashioned Digital Rectal Exam that feels for abnormally sized prostates, but chances are your PSA would already be elevated.
