What is Mouth Cancer?

Mouth cancer, or oral cancer, affects the lips, tongue, gums, floor/roof of mouth, inner cheeks, or tonsils, mostly squamous cell carcinoma (90%). Stages I-IV, with early often curable. In 2025, ~54,000 US cases, more in men, linked to tobacco/alcohol.

Symptoms

Symptoms include persistent mouth sores/lumps, white/red patches (leukoplakia/erythroplakia), pain/swallowing difficulty, ear pain, loose teeth, numb chin, voice changes, weight loss, swollen nodes. Advanced causes bleeding or neck masses.

Causes

Tobacco (smoking/chewing, 75% of cases), heavy alcohol, HPV (oropharyngeal, types 16/18), betel nut, poor oral hygiene, sun exposure (lip), and genetics. In 2025, HPV causes 70% oropharyngeal cancers.

Diagnosis

Diagnosis uses oral exam, biopsy, imaging (CT/MRI/PET), and HPV testing. Staging TNM. In 2025, AI oral scans improve detection.

Treatment

Surgery removes tumor/margins/nodes, with reconstruction. Radiation/chemotherapy adjuvant. Targeted (cetuximab) for EGFR+, immunotherapy for advanced. In 2025, de-escalation for HPV+ reduces toxicity.

Future Outlook

In 2025, 5-year survival 65% overall, 85% localized. HPV vaccination reduces incidence. By 2030, immunotherapies could achieve 75% survival.
