I just watched the Q and A on prostrate cancer from Mayo Clinic posted on Oct. 3. It has a lot of useful information about psa testing, biopsies, treatment options, side effects, and reoccurring cancer. I wish I had seen this video when I was diagnosed with cancer a year ago. I discovered that my local urologist didn't use the most current procedures in my diagnosis. It reinforced my decision to seek out a research hospital like Mayo to pursue my treatment. They followed some procedures in my diagnosis that my local doctor left out.
My Mayo radiation oncologist also used a treatment that included proton beam radiation with Antigen Deprivation Therapy that increased my survival chances by 20% over just radiation. By the way, you can go on the American Medical Association web site and register as a patient and access their reports on prostrate cancer. I used the site to verify my radiation oncologist's treatment choice. Unfortunately, the report indicates that many doctors don't use that treatment option for advanced forms of my cancer (Gleason score of 8+).
I think my anxiety level would've been a lot lower, if I had known that the medical staff were using the most recent knowledge to determine If I had cancer and it's extent. Also, what are the factors that determine the best treatment option.
The two main take aways I got from the Q and A were have an MRI before having a biopsy. It will not only tell if you have cancer, but also focus the biopsy. The second was the difference in the treatment based on age. My radiation treatment was appropriate for my age (73), but if I was younger, surgery would've been more appropriate.

Hope this is helpful.
