Hi,

Thanks for your query.

Red spot which comes and goes is very less likely a cancer, because cancer will grow slowly and never regress automatically. So you need not worry about cancer.

It possibly could be an ulcerative patch or reaction to allergens (peanuts/environmental) or it may be side effect of the inhaler you are using.

There is usually a strong inducing factor like smoking or chewing tobacco, or family history for oral cancer, though it is not a pre-requisite. If you have any one of these predisposing factors, then it will be better to get evaluated from an ENT specialist.

You have a feature to upload images of your lesion by yourself, at the right side of the query page. Please utilize that, so that I can answer your query in a much better way.

Regards
