I noticed a marble sized non movable hard lump on lower portion of sternum. I am currently on biological and immunosuppressant therapy for active psoriatic arthritis. The lump is tender to the touch. No chest pain or SOB. I am 47, female. Should I be concerned?
Hi, dairy have gone through your question. I can understand your concern. You may have some benign cyst or some soft tissue tumor like lipoma or neurofibroma.  No need to worry.  Excision biopsy should be done.  Consult your doctor and 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.
