PROSTRATE REMOVED 13 YEARS AGO. PSA READINGS STARTING TO INCREASE. LATEST .32 PSA. WILL BE GOING FOR BONE SCAN AND PET SCAN. I'M CONCERN ON RADIATION TREATMENTS. HISTORY I HAD A LARGE KIDNEY STONE 15 YEARS AGO AND HAD A BONE SCAN THAT HAS LOW LEVEL RADIATION IN THE FLUID INJECTION. THE NEXT YEAR MY PROSTRATE EXAM SHOWED A PROBLEM. HAD MY PROSTRATE REMOVED WITH SOME LYMP NODES REMOVED. STILL FULLY FUNCTIONAL. NO DETECTABLE PSA FOR 13 YEARS. HAD A BONE SCAN FOR NON RELATED ISSUE 2 YEARS AGO. AFTER THAT MY PSA BECAME DETECTABLE. NOW THEY WANT ANOTHER BONE SCAN AND A PET SCAN. MY CONCERN IS IT POSSIBLE THE LOW LEVEL RADIATION SCANS CREATING A CANCER PROBLEM. LOOKING FORWARD IT SEEMS THE COMMON SOLUTION WOULD BE RADIATION TREATMENT. MY GUT IS TELLING ME IT JUST DOESN'T SOUND RIGHT. IS THERE ANY OTHER SOLUTION. VERY CONCERN RADIATION WILL ALSO AFFECT MY CURRENT FULLY FUNCTIONAL SYSTEM. HOW MUCH SHOULD I EXPECT LIFE EXPECTANCY TREATMENT VS NO TREATMENT. THANK YOU IN ADVANCE FOR YOUR INPUT. HAVE A GREAT DAY.
