I have noticed a lump, about the size of a marble, came up in about a week, just below the right jaw line, where the jaw turns upward towards the ear, right in front of the point. I am 68 years old, and never been diagnosed with any illnesses. I do not take medication of any kind, have no alergies, never catch the flu, colds,headaches or any other symptoms of illness. No cancer in family history. I hesitate to see a doctor, just to tell me it's nothing except a swollen lymph node or something, since I don't have medicare part B. What do you think? Thanks for your help.
