I Am a Hypochondriac

The white patches from a few months ago on my gums that went away have reappeared. I am terrified this is oral cancer. It’s been a few days, and everything I read says that if no improvement within two weeks to go see the dentist/doctor. I am terrified to do so because I dont’ want the news that it’s cancer and I have to get my face cut open in order to remove it. I hope this just goes away....I have a regular check up scheduled end of next month and will bring this up...but I REALLY hope it’s gone by then ( or sooner).
