Improve Your Odds Against Oral Cancer
Oral cancer can strike anyone, but the leading risk factors include smoking, chewing tobacco and drinking alcohol. In recent years, human papillomavirus (HPV) is thought to be an additional risk factor, leading to more cases in women and younger patients.
Warning signs of oral cancer:
- Red and/or white spots in your mouth or on your lips
- Sores in your mouth or on your lip that don't heal
- Unusual changes to the surface of your mouth or lip tissue
- Bleeding in the mouth
- Loose teeth
- Difficulty swallowing
- Ear pain
- Numbness of the tongue or other mouth parts
- Jaw swelling
New Tests Detect Cancer Sooner
New screening tools may help to find oral cancer sooner. Light contrast screening allows oral cancer to be detected and treated earlier than in the past. Called fluorescence visualization, this test uses light to distinguish between healthy tissue and tissue that is potentially abnormal.
A brush biopsy is often done as a follow-up to light contrast or if there is an obvious area of suspicious tissue. A dentist uses a brush to take a tissue sample from the suspicious area and then sends it to a laboratory. If the results are positive, a full-scalpel (also called surgical or incisional) biopsy is performed.
Both screening tests are performed in addition to traditional manual screenings. If abnormal tissue is detected, the dentist will refer the patient for a full-scalpel biopsy to determine a definite diagnosis and possible treatment.
