Alan I'm glad your OK, thank God it was not cancer. My dad fought prostate cancer for 14 years and it finally killed him back in '05. I've seen all the gory details.
Plumbing problems are frightening. On a more humorous note, I had a wreck diving buddy a few years back. We did some real dangerous crazy stuff together. Deep, dark, real spooky penetrations in Atlantic wrecks like the Andrea Doria. Guys would get killed doing this every year. He went on to become famous and has had a show on the History Channel for a few years now. He was also a combat medic in Vietnam, so a fearless guy, big balls. I asked him once what he fears most. He said "When I get old and something goes wrong with my blow hole."
