[|Human|] Hello, my son had a stage 3 brain tumor on the left side 8 years ago....removed successfully except for losses in his abilities,however, he had surgery on his lip a few months ago and now this lump ( size of a tennis ball) under his R arm they are calling possible Melanoma. They are ( considering) taking it out........he is so worried that they might even take his arm off. His wife tries to console him ( and herself) that it is just the lump. His appointment is for next Thursday. Please help me understand......
[|AI|]  Hi, Thank you for posting your query. I can understand the personal and physical disabilities your son is going through at this stage. He needs all possible care and compassion to deal with this. The exact nature of the lump in the arm can only be ascertained after the surgery, when we receive the biopsy report. If it comes as melanoma, then, it would be considered as a more advanced stage disease than stage 3. However, if it is something unrelated to the melanoma, then, it would be good news. Best wishes, Chat Doctor.
