i have a lump on my right side rib on the back side, it moves when i touch it and its not hard and i have no pain. im concerned because i noticed it a few months ago and its much bigger now. what could it be? im 24 years old im 55 and weigh 118 pounds.
Common lumps occurring in the back are lipoma(a benign Tumor of fat tissue), sebaceous cyst, neurofibromas. Since your lump moves on touch and is painless, it goes more in favor of lipoma. No need to get worried as it's a common condition. Look for other swellings similar to this, else where. Consult your surgeon and get it excised and send for biopsy.
