<s>[INST] I have a bump on the inside of my lower lip, it just appeared this past Sat. no changes in diet or food. It looks similar to a small wart its solid, not a blister. I have, of course been running my tongue over it. it is not irritated just there. i just lost two of my pts to what started to oral cancer. At the end they did not even look human. So of course my mind has gone astray. any suggestions?? trying to see a dentist as i have had all my teeth break of in the last year due to a 27 year battle of dry mouth due to anti anxiety med and antidepressants. [/INST] Hi, happy to help you on your health concern on part of Chat Doctor! In the present case of LOWER LIP swelling or lump, if I were your consulting physician, I would just say you, nothing to worry! Just avoid rubbing or hitting over it; and avoid hot/spicy foods; it might go itself! As per your description, it is a benign harmless lesion like mucus retention cyst or common papilloma like some fibroepithelial polyp. In any case this could not be cancer... Take caution not to get injured there as this might invite infection. If you are still worried, please get examined by a surgeon or get some FNAC like cytological examination or revert to us. Hope you got your answer. Please feel free to write to us if any more queries. Wishing you the best health! </s>
