My friend sent me an X-ray of his chest. There's s huge black spot in his upper right lung perhaps. It's located about the nipple seems to possibly be the size of a lemon. No bad... Just tenderness, his back hurts more than his chest. Had no pain and was thrown off by this X-ray. Doctors said to not see a chiropractor and that they will have test results in two days. It's really bugging me and I'd like to get an idea of what this possibly could be. Thank you so much
