Orangeman, hon, you're only 16. You don't have throat cancer. You have a strong tendency to worry that you have various medical conditions. But you don't have throat cancer. Even if you did, you wouldn't be able to tell it yourself, and chances are it'd start out with a growth or a tumor, not a sore throat. Some oral cancers start out with whitish patches, but then so do some types of infections, too. Oral and throat cancers tend to happen in older folks who've had a long history of tobacco chewing, snuff dipping, cigarette smoking, etc.

Chances are, you simply have a sort throat or soreness from drainage down the back of your throat. Summer is allergy season, you know, and sore throats are a classic symptom of allergies. If it worries you so much that it's stressing you out, you can go to the doctor. If your regular doctor thinks it's serious, he/she can send you to an ear-nose-throat doctor. In the impossibly unlikely event that someone did think it was an early malignancy, they'd have to take a sampling of tissue and send it off to a pathology lab to be biopsied.

Try to stop worrying and take some Benadryl (50 mg) and see if that clears up your drainage and stops the soreness. You can also try Aspergum, which is aspirin-containing gum, which is also good for a sore throat.
