I m a 46 yo female. I have a lump below my left tricep, it s not visible to the eye, but it s palpable. My mother had a melanoma in this spot. I asked my dermatologist to look at it. She said she could feel a mass and is sending me to a plastic surgeon for a biopsy. What could it be?
HI, Good Evening. Thanks for your query. I studied the query in-depth.It's the sheer fear of mothers melanoma, which has made you panicky. I understand your concerns. I need to have more info-which I can get after clinical exam only. With whatever facts told in your query, I would try to give most probable causes to help you to reduce your worry and to plan treatment with your plastic surgeon before biopsy.-Your dermatologist has asked for a biopsy, means there is no melanoma factor / or the skin factor -involved in your lump and its mostly of subcutaneous lump, and you should relax on that positive grounds.-Mostly in my opinion-Lipoma/ fibromyoma-as lump is painless.-Excision Biopsy-would fix the differentiation of the causes of the tricep lump.-You need not worry of the outcome as both these tumors are benign.-Hope this would help in discussing with your plastic surgeon.-Wishing you early recovery and good health.
