My 14 year old son has a hard lump on top of his shoulder. It s about the size of a grape and we just noticed it, he s not sure how long it s been there. . He says it s painless and it seems to be stationary. I made a dr appt for next Monday. I m very worried it could be some sort of cancer. What could it be?
Thanks for your question on Chat Doctor. In my opinion you should not worry much about this swelling. By your description of swelling, I think your son is having either Desmond or lipoma. Both are soft tissue swelling commonly occurring. Both are painless, non-itchy and non-tender. Almost 100% benign. Dermoid contains fibrous tissue while lipoma contains fatty tissue. So no need to worry much. Get done excision biopsy from the swelling. This will give you correct diagnosis.  It seems Desmond mostly.
