Oral cancer screening is a quick, painless exam your dentist performs to look for early signs of cancer in your mouth, lips, tongue, and throat. Most oral cancers are caught late — which is why the five-year survival rate for head and neck cancers in Canada sits at 64%, and outcomes drop sharply when diagnosed at an advanced stage. Early detection changes that significantly. Risk factors include tobacco use, heavy alcohol consumption, HPV infection, and prolonged sun exposure. The exam takes fewer than five minutes and requires no preparation. If anything looks suspicious, your dentist refers you for further testing. A screening alone does not diagnose cancer. At Ethos Dental Studio in Langley, oral cancer screening is part of every routine dental exam. What Is Oral Cancer Screening? Oral cancer screening is a visual and physical examination of your mouth, lips, tongue, gums, throat, and jaw. Your dentist looks and feels for lesions, unusual patches, lumps, or any tissue that doesn't look or feel the way it should. The areas examined include: Inner lining of the cheeks Roof and floor of the mouth Gums Lips Tongue (top, sides, and underside) Tonsils and the back of the throat Jaw and neck (felt externally for lumps) The exam is quick — typically under five minutes — and requires no preparation on your part. It happens as part of your regular dental checkup, so there is no need to book a separate appointment. Why Early Detection Matters In Canada, the five-year net survival rate for head and neck cancers — the category that includes oral cancer — sits at 64%, according to the Canadian Cancer Society. That number drops sharply when cancer is found at an advanced stage, and more than half of oral cancer patients receive their diagnosis at exactly that point. When oral cancer is caught early, it is far more treatable and often requires less invasive intervention. That is the entire purpose of routine screening — catching tissue changes before they become harder to treat. The cruel irony of oral cancer is that it is not especially difficult to detect. It sits in a part of the body a trained clinician can see and touch directly. The reason outcomes are poor comes down to awareness — many people don't know that a routine dental visit includes an oral cancer check, and others put off care until something is visibly wrong. Warning Signs of Oral Cancer Most early-stage oral cancers cause little to no pain. That is what makes them so easy to miss without a professional exam. Still, there are warning signs worth knowing: White patches (leukoplakia) — thick white areas inside the mouth that cannot be wiped away Red patches (erythroplakia) — flat or raised red areas, which carry a higher malignancy risk than white patches Sores or ulcers that do not heal within two weeks A lump, thickening, or rough spot on the lips, gums, or inside the cheek Persistent sore throat or a feeling that something is caught in the throat Difficulty chewing, swallowing, or moving the jaw or tongue Numbness or pain in any area of the mouth, face, or neck Unexplained bleeding in the mouth Loose teeth with no obvious dental cause A swollen lump in the neck — which can signal that cancer has spread to lymph nodes None of these symptoms confirm cancer on their own. Many have benign causes. But any of them lasting more than two weeks warrants a professional evaluation. Who Is at Highest Risk? Oral cancer can occur in anyone, but several factors raise the risk meaningfully: Tobacco Use Smoking cigarettes, cigars, or pipes — and using smokeless tobacco such as chewing tobacco or snuff — are among the strongest risk factors for oral cancer. The carcinogens in tobacco damage the cells lining the mouth over time. Heavy Alcohol Use Alcohol alone increases oral cancer risk, but the combination of tobacco and heavy alcohol consumption multiplies risk dramatically. The two together are responsible for the majority of oral cancer cases. HPV Infection Human papillomavirus (HPV), particularly HPV-16, is a growing cause of oropharyngeal cancers (cancers of the tonsils and base of the tongue). HPV-related oral cancers are rising in people who have never smoked. Sun Exposure Significant cumulative sun exposure raises the risk of lip cancer, particularly on the lower lip, which receives more direct UV radiation. Age and Gender The risk of oral cancer increases with age and is greatest after 50, according to the Canadian Cancer Society. Men are also diagnosed more often than women, though that gap is narrowing as HPV-related cases rise across all demographics. Even without any known risk factors, routine screening makes sense. A meaningful portion of oral cancer patients have no obvious risk factors at diagnosis. What Happens During the Screening? Your dentist will use a combination of the following methods. The process is entirely non-invasive. Visual Exam Your dentist examines the inside of your mouth under good lighting, looking for lesions, patches, or any tissue that appears abnormal in colour, texture, or size. Palpation Your dentist uses gloved hands to feel along your jaw, the floor of your mouth, your tongue, and the sides of your neck. They are checking for lumps, thickening, swelling, or any area of unusual firmness. The entire exam takes fewer than five minutes. There is nothing to prepare, and there is no discomfort. What Happens If Something Looks Suspicious? A screening does not diagnose cancer. It identifies areas that need further investigation. If your dentist notices something concerning, the next steps typically include one or more of the following: Watch and wait: Your dentist may schedule a follow-up visit in one to two weeks to see if the area has changed, grown, or resolved on its own. Many benign lesions — canker sores, for example — heal within that window. Cytology : A provider brushes or swabs cells from the suspicious area and sends them to a lab. A pathologist examines the cells under a microscope for abnormalities. Biopsy : A small sample of tissue is removed and sent for pathological analysis. This is the only definitive way to confirm or rule out cancer. Depending on the size and location of the lesion, your dentist may perform the biopsy in-chair or refer you to an oral surgeon or specialist. Results typically return within three to five days. How Often Should You Get Screened? For most adults, oral cancer screening at every routine dental checkup — typically every six months — is sufficient. Twice-yearly visits also give your dentist a consistent baseline, making it easier to spot changes in tissue over time. If you have elevated risk factors (tobacco use, heavy alcohol consumption, or HPV history), more frequent monitoring may be appropriate. Talk to your dentist about a schedule that reflects your individual risk profile. Can You Screen Yourself at Home? A monthly self-check at home is a useful habit and one that some healthcare providers recommend. It is not a substitute for professional screening, but it can help you catch changes between appointments. Here is a simple routine: Face and neck : Stand in front of a mirror. Look for any new swelling, lumps, or asymmetry on your face. Run your fingers along your jaw and down the sides of your neck. Lips : Pull each lip away from your teeth. Check for discoloration, sores, or unusual patches. Feel for any lumps. Cheeks : Gently pull each cheek outward. Look for red or white patches. Feel along the inner surface for thickening or tenderness. Gums : Use your thumb and index finger to feel along the gum line on both the outer and tongue-side surfaces. Tongue : Pull your tongue out gently and check the top surface, tip, and both sides for swelling or discoloration. Then touch the tip to the roof of your mouth and examine the underside. Roof of mouth : Tilt your head back and look at the palate for discoloration or ulcers. Floor of mouth : Lift your tongue and feel the floor of your mouth for any tenderness, swelling, or unusual lumps. If anything looks or feels different from last month, or if a sore hasn't healed after two weeks, call your dentist. Don't wait for your next scheduled appointment.
