I have a scab on my head that often starts bleeding and never heals. It has been there for almost 2 1/2 years. While it is very annoying, it is not at all painful. I thought nothing of it until recently a co worker told me of the same situation that happened to her brother and it was cancer, he actually passed away. So now I'm alarmed! PleSe give me some help as I do not have insurance anymore. So before I go in medical debt I want to be sure it is valid.
