[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  He may have some benign cyst like ganglion cyst or other cyst.  Chances of cancer is very rare.  But we should rule out. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Complete surgical excision is the treatment of choice for benign cyst. 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.
