PSA

Treatment
My husband has a new primary care doctor. He had an appointment yesterday and they did another blood test to check his PSA. It is now a 7? Is that possible? Just a few weeks ago before he started hormone treatments it was 45. He started hormone treatments two weeks ago and now it is a 7?

I know the cancer isn't gone. His doctor told him the bone scan showed cancer throughout his body but if that is the case how is the PSA down to 7? Is this logical?

I am also searching for nutritional ideas for my husband. The medical profession hasn't suggested this yet but I believe that if I can introduce a new diet it would help.
