I have two mouth ulcers at the moment as I think I am quite low but I have now noticed two hard lumps that have appeared under my chin. One is under my chin and the other is in my throat and quite painful. Any ideas what they are? I also have a pea sized lump in my cheek which has been there since I was a child. It has never bothered me and the Dr said it could be just a small stone. My mother had breast cancer a while ago and I am in the dodgy area but my grandfather also died from cancer of the throat and i am not just curious.
