I have no idea what symptoms of jaw cancer are, but if you are not seeing a dentist regularly, that is the first step you need to take - see a dentist for x-rays. Better yet, see a dental oncologist for x-rays. Or, go to a cancer treatment specialty hospital for diagnosis. Be vigilant and PERSISTENT in your efforts. My daughter has tongue cancer that went undiagnosed for 6 months and she finishes her 30th day of radiation tomorrow, after 2 courses (4 rounds)) of chemo and surgery to remove part of her tongue and 9 lymph nodes. Radiation is the worst - and the effects of it will last 6 months to a year. If the cancer comes back, she only has a 10% chance of beating it. Oral cancer is nasty - because it is seen by everyone - it is not easy to hide the disfiguring scars and the radiation burns. Just be persistent - keep getting opinions until you are satisfied with the answer. And, if you smoke AND drink - quit now. Those are prime contributing factors to oral cavity cancer. Oral cancer is one of the fastest growing types of cancer now - especially among people 40 and younger. I suggest you go to SPOHNC.org for more information about this type of cancer.
