So those of us with unknown primary, how do you cope? Not knowing is the absolute worst for me personally. I just turned 59, had been in good health and this came out of the blue. When I was diagnosed, I thought, ok, I'll do everything they (Dr's) say and be done with it. Welp, I've done everything my 15 doctors have told me to do & there's no end in sight and no new news on the latest PET scan. It drives me crazy!
