How do i tell if i have mouth cancer?

Check your mouth.: Mouth cancers can present as nonhealing ulcers that can be painful. Orophayngeal cancers may present late with sore throat and earache. Patients can have painless lymph node enlargement. Staging depends on the size of tumor and lymph node involvement.

See a doctor: Cancer of the mouth requires a biopsy. You should see your doctor.

Changes in mucosa: White patches, ulcer, indurated/hard area, bleeding, may suggest cancer. Diagnosis may require biopsy and examination of tissue by a pathologist.
