I had pap. cancer around 9/01. I was 25 and a mother of 2 small children. I had a TT, RAI, clean follow up scans, etc. I took care of myself. Had bloodwork done often enough and my TSH was under supression. Yet last year, I had a recurrence. I had a radical neck dissection and RAI in Apr. My scan came back clean.
It happens, I guess. I try hard to stay positive and pray that it never comes back.
