DDL - ask your URO you could be like me . I am posy surgery 5 years ago and 2.5 years ago wit 22 sessions of Salvage and NO ADT at 0.14 . My PSA hovers in the 0.061 to about 0.032 PSA right now . My GP and my URO say that very likely I have a very small amount of cells in the pelvic area that are NOT cancerous and did not die ... so they push out a small amount of PSA over time . They said that IF they were cancerous the PSA would have a different pattern . So , they are not too worried about me and I was discharged from the Victoria Hospital ! Maybe this is your case or ? You have some VERY LOW PSA numbers - so treatment did work well. We are here for you ! God Bless Sir . James on Vancouver Island .
