Hello I have a bump/ball starting to grow on the top of my mouth. on the roof. I am scared it’s a form of cancer as it is growing pretty fast. It was flat 2-3 days ago, and now it’s growing and I can see a ball forming. I would like to know how long would be alright to wait before seeing a doctor because I am in the United States now and need to go to France to see a doctor. My ears hurt a bit, and it’s making it a bit tough to eat as it does hurt.
