<s>[INST] There is a painless lump on the inside of my lower lip that feels hard when I press against it with my tongue. I can feel several tiny bumps all over my lower lip that have always been there, but I have never noticed this lump before. Should I be worried? [/INST] Hi, dairy have gone through your question. I can understand your concern.  You may have some benign cyst or tumor, or it may be squamous cell carcinoma of lip.  You should go for examination and if needed go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
