<s>[INST] Hi, I'm a 36 year old women with a history of melanoma on my right breast and abdomen. I've had 4 shwanomma tumors taken out of my spine L5,S1 area. I recently got out of the hospital after having a staph infection in my kidneys, that had gone on four 3 months with fever. While I was there they found many nodules on my lungs. I have a big lump on my left shoulder, near my clavicle, next to my neck. My physician gave me an MRI of the soft tissue and nothing was found. Now this mass is getting bigger and giving me chest pain and constant shoulder pain and arm pain. What kind of doctor should I see for this shoulder mass? An oncologist of an orthopedic surgeon? Thanks [/INST] Hi, dearI have gone through your question. I can understand your concern.You have history of melanoma and schwanomma. SO you may have metastatic melanoma, schwanomma, lipoma or lymphnode enlargement due to infection or other lesion. You should consult general surgeon first. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. If it is benign then no need to worry. If it is cancerous then you should consult oncologist and take treatment accordingly.Hope I have answered your question, if you have any doubts then contact me at bit.ly/Drsanghvihardik, I will be happy to answer you.Thanks for using health care magic.Wish you a very good health. </s>
