Instead of a biopsy, I'm trying a new prostate cancer test from the University of Michigan. I'd found it and asked my doctor about it; he looked into it and was impressed. So we're getting our Science® on.
Basically the test looks for DNA markers that are only present when there's a tumor. It's non-invasive and claims to be as accurate (or more) than a biopsy.
We'll see, but I expect I'm feeling much better today than if I'd had a biopsy.
