Hi, my boyfriend who is. 62 recently had a sarcoma removed on his forearm. Seven visible stitches plus dissolvable. Now over the last 10 days he has developed, only under his left arm pit, three swollen welts. The results of the biopsy said that he the carcinoma had not spread anywhere, as margins that were removed around it were clear. I have asked him to see the surgeon again, but he is ignoring my requests.
