<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a lump on front lower part of right leg. Its about the size of a quarter. Ive noticed it a long time ago put never payed attention to it because it was painless. But recently got some pain near that area while walking. I was wondering what it can be and if i should be worried?  <response>: Hello! Welcome to Chat Doctor. This swelling can be a lipoma or sebaceous cyst. Both are benign lumps. In my clinic, many patients with similar complaints come, to whom after clinical examination, I advise FNAC - fine needle aspiration cytology if in doubt clinically. Excision BIOS is usually done i.e. swelling is removed under local anesthesia sent for histopathological examination. Hope this information is useful. Wish you healthy life. Thanks. Regards.
