The reality is this... Most drs don't like to admit it... but an oncologist i know here actually said... there is no such thing as a recurrence - all it means is - they didn't get it all in the first place.

and often the second time around it usually rears it's head within the first 18 months - at the outside 3 years. Anything after that could mean its a super slow growing cancer or it's a new cancer.

I too would push to have the spots biopsied asap. Think about it - you wait for the thrush to go away and then have to wait up to two weeks for results... that's easily two months before dx if it is a recurrence.
