I am scared I won't be taken seriously when I go to my doctor (on Monday). I am an 18 year old female, I was a heavy smoker for 4 years (I am down to 1 cigarette a day from a whole pack). I am HPV negative.

I have been worrying myself endlessly researching oral cancer online. It is more common than Leukaemia which is frightening. It is in the rise amongst young women in my age group.

I am NOT a hypochondriac, I feel I do have good reason to be worried. Whenever my estrogen/progesterone levels "peak" (when I have my period in specific) I get a nagging ache in my tongue. Estrogen has been linked to the progression of oral cancer!! (article I read: http://www.medscape.com/viewarticle/735284

I have an endocrine disorder which stops me from menstruating. I can go months without having a period, and when I do, my tongue worries me to the nth degree.

Here are the areas of my tongue that are worrying me:

What steps do I need to take to get these things biopsied? Do I go to a dentist? A doctor? An ENT? I am clueless!! I cannot sleep because I am so damn worried
