[|Human|] I am female, 28 years old, 5 feet 7 inches, no history of lumps or other health ailments, 24 weeks pregnant. Just noticed a few days ago a half dollar sized lump on my lower left back. Not painful to the touch and does not have any color. I have experienced back pain in this area on and off for the past few weeks but I am not sure if it is related seeing that I have an expanding stomach and have gained 17 pounds or so quite recently.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some soft tissue tumor like lipoma or neurofibroma or something else. 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. 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.
