<s>[INST] I am 51 yrs old. I have an egg sized lump located in my lower back close to my spine. My doctor says it s a lipoma and nothing to worry about. Sometimes it hurts and cannot sit in a hard back chair as it puts pressure on it, otherwise it does not hurt. Should I be worried? [/INST] Hi, dairy have gone through your question. I can understand your concern. You may have soft tissue tumor like lipoma, neurofibroma, dermatofibroma or some other tumor. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Surgical excision is the treatment of choice for most of the soft tissue tumor. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health. </s>
