I'm six years out from double mastectomy for IDC and recently had an ultrasound for a pain on the cancer side which turned out to be benign, actually they couldn't find anything and think its muscular. Now it still hurts and went back to the dr. and he wants me to have a PET scan. I am terrified! Should i have just accepted that its muscular or go through a PET scan. Would a recurrence show up and where would it be. I was node negative at the time of my diagnoisis. Having a breakdown and going down the rabbit hole with this one rather quickly! I still take letrozole. Thanks for any advice on navigating the first PET.
