I have the two red bumps far back on the side of the tongue. I've been getting random white bumps in cheek. Now I have hard lump in tongue. I'm 16 cancer?

Lump in tongue. Very rarely a cancer. You may be biting your tongue and check during sleep, especially if you grind you teeth. Try a mouth guard. Use meditation, and yoga to relax.
Least Possibility. You are 16 only. Anyways, make a trip to your pediatrician/ family doc's office to have an exam and diagnosis.
