Hi, my seventeen year old son has had a hard white lump in the middle of his chest for a couple of years. I took him to see his local GP about a year ago and he said that he did not think it was cancer after looking through a little magnify glass. It is not painful, although has doubled in size. what could it be? Thanks, Angela
Hi, From history it seems that he might be having sebaceous cyst, increasing size gradually. Consult surgeon and get examined. If cyst is there and increasing the size, it required excision of cyst with removal of sac. Ok and take care.
