<s>[INST] Hi,  Ive been noticing for a while (perhaps around a year) that I have a small soft bump on the edge of my upper lip on the right side.  I havent bitten myself or hurt myself in any way that I can remember.  I thought it was just the shape of my lip on that side for a while, then it seems to have grown a little.  This morning I noticed it is coming to a small head (a little like a pimple), but it is not painful in any way and when I run my tongue along it, it just feels like a little bump.  Could it be anything serious like cancer or is it more likely to be a mucocele?? Please advise.  Thank you [/INST] Thanks for your query, I have gone through your query. The soft tissue lump over the upper lip could be a muscle or fibrous or a fibrosis muscle(since you are giving history of one year). The muscle will appear as a soft swelling with a bluish tinge. Usually it ruptures and again comes back. Consult an oral physician and get it ruled out. It is a benign lesion nothing to worry. You can get it excised under local anesthesia. I hope my answer will help you, take care. </s>
