What do mouth cancers look like?

Variable: Anything from a red, pink or white patch that stands out, to a usually-painless ulcer that persists for more than two weeks to a cauliflower-like bump. Mouth cancer often goes through a pre-invasive stage that a physician can spot, biopsy, and treat with expectation of a cure.

Ulcers.: Oral cavity cancers often present as nonhealing ulcers that can be painful.
