A persistent sore, lump, red or white patch, or unexplained change in your mouth deserves professional attention. These symptoms can have several causes; they do not establish a cancer diagnosis.
Changes to have checked
See a dentist or physician if a mouth or throat symptom persists for more than two weeks. Examples include a sore that does not heal, a neck lump, numbness, ongoing hoarseness, or difficulty chewing or swallowing. Seek help sooner for worsening symptoms.
Risk factors
Tobacco and heavy alcohol use increase risk. HPV is associated with many cancers in the back of the throat, and sun exposure can contribute to lip cancer. Poor brushing alone should not be described as the main cause.
What a dental examination can tell you
Your dentist can examine your mouth and neck and arrange further evaluation if something looks unusual. A screening examination does not replace a biopsy or other diagnostic testing when needed. Early detection matters, but a cure cannot be guaranteed.
