Hi again. Try not to worry a tongue lesion or tumor (to me a lesion is more of an open sore or damaged looking area) necessarily always being cancer. It's not the case. My concern is leaving something for too long then finding out far too late that it is cancer. That's why I always push people to get an answer.That said do be forthcoming with your next dr. basically say, I had a biopsy a while back. The problem persists, I would like another biopsy perhaps remove the lump period so there is no need for worry. If you go on about drs not listening they will tune you out and chalk it up to some paranoia. Its gone on long enough you need an answer. best of luck
