Yeah, like a lot. I think I have had three or four. The cancer was in remission for 5 years. Zero (or undetectable) PSA. But.... it came back. Now that it is back the doc wants a blood test once a month. Had a scan, they found the spot. They zapped it again (radiation). That spot went away. But now there is a new one. Sooooo, more scans. I'm a regular.
