[|Human|] My father had his R finger removed at first joint approx 1.5 yrs ago (finger nail melanoma). He now has a number of lumps under his skin running up his R arm and on his chest, he also has a number of wart like cluster on his R shoulder. He has had  scans of organs and all look ok, what stag of melanoma would he be at?
[|AI|]  Hi! Thanks for sharing your fathers' health problem with Chat Doctor! After going through the history and present symptoms, I feel, if I were his treating physician, he should have gone for a needle biopsy or some diagnostic biopsy from the chest or lung lesions as positivity of melanoma cells in the lungs means stage 4. Therefore, the nodules in his body following surgery are likely to be metastatic in nature and I wonder if the scans are really negative in this case! Please see your surgeon ASAP for some biopsy test and confirmation, and also, please revert to us! Regards!
