IMHO, might be a good idea to get a second, or even third, opinion on whether or not to get other treatments T.C.. A year ago from last September my oncologist wanted to put me on radiation treatments in order to drop my PSA count from a consistent 1.5 to below 1. Told him I'd get back to him in a couple of weeks with my answer. Talked to a GP with a lot of years practice and a nurse with 30 years, and both told me in no uncertain terms NOT to have the treatment.The tumour in my testicle has been confirmed as a seminoma, which is a type of malignant cancer. Specialists at a hospital in another city close to me will look at my case to determine whether they think I need other treatments or, in light of the negative CT scans, whether the removal of the testicle followed by regular monitoring will be enough.
A few months later, due to my PSA increasing from a consistent 1.5 to a one-time 2.7 he wanted to put me on a chemo regimen of two fairly strong pills, one of which was prednizone, can't remember the other but it was very strong. I refused this treatment as well because I felt just fine, and the PSA dropped back to the familiar 1.5, which it's been for the past five years, since I started the Eligarde treatments, which are very benign, require only day surgery every three months. In fact, I often forget I have prostate cancer.
Well, hope this helps T,C. and all the best, whatever you decide and I'm praying for the best possible outcome.
FWIW

Some of the cancer was still there, a little had grown. He then had radiation on a small tumor. Because he has some sort of gene mutation, not all chemo drugs will be effective. He is taking a pill now and we have a scan sometime this month to see what's going on.
