I have had this hard red lump on my palate for almost 2 years. At first, it was a bit smaller, but now I just realized that its size might have doubled. It is hard, reddish, not sore unless I press it quite hard.

I am worried that it might be a oral cancer. I cannot visit a dentist at a time since I am in a foreign country where no one speaks English, so I am a bit troubled. :(

Please help.
