This is Keratosis of tonsil. It's not cancer.
Tonsillar keratosis is characterized by appearance of multiple white projections from cryptal orifices of the tonsil, lymph follicles, the posterior and the lateral pharyngeal walls, posterior part of the tongue and glosso-epiglottic fold.
This condition usually affects the tonsils. During deglutition, the contraction of the muscles prevents food from coming with intimate contact with the surface. It thus permits these projections to grow. The horny projection breaks up into layers. Between these layers multiple organisms multiply and grow. The toxins released from these organisms are absorbed by the tonsillar tissue.
