I'm 19, female, non smoker and I drink only occasionally.

For the past few months (but more strongly in May and June) I have been feeling a lump in throat. I have visited my doctor who did blood tests for thyroid problems, but the tests came back fine and she said to visit her again if the problem persists (I will do so next week when she comes back from vacation) but I have really started to panick in the last few days as I have found a few lumps in the left and right side of my mouth behind the tonsils and tongue. I don't know if it's serious or not and I'm really afraid it's cancerous. I don't have sore throat or any other symptoms of throat cancer, but I'm really afraid it could be cancer. The lumps are about 6mm wide and the same color as flesh.
