Its ok to ask questions, so please dont feel the need to apologize. You are scared which is normal. Please try your best to stay calm about the situation. Its NOT cancer til the biopsy says it is.

Everybody is different and can have different symptoms. Tumor location also plays a part in feeling jaw or ear pain. My tumor was located inside my L cheek and I had another seperate tumor behind my top L molar. I had no ear pain or pressure at all.

A cancerous tumor will not grow and shrink like what you are describing. It sounds like smoking, eating and drinking irritate the area and it in turn reacts.

Anyone can quit smoking, its not easy but its something that can be accomplished. Its all mind over matter. I am a former smoker. I simply threw my cigs out the car window on my way to one of my oncologist appointments, never to smoke again. There are several products out there to assist you in quitting. Its all in your mind, IF you want to quit you will. Hope that you seriously consider quitting after this scare has opened your eyes.
