Oral cancer screening is a quick examination your dentist performs to look for early changes in your mouth, lips, tongue and throat. It usually takes fewer than five minutes and needs no special preparation. At Ethos Dental Studio in Langley, it is part of routine dental examinations. Screening identifies areas that may need further investigation; it does not diagnose cancer.
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 tissue that looks or feels different from the surrounding area.
The examination happens as part of your regular check-up, so you generally do not need a separate screening appointment. Tell your dentist about any symptoms or changes before the examination begins.
- The inner lining of the cheeks
- The roof and floor of the mouth
- The gums and lips
- The top, sides and underside of the tongue
- The tonsils and back of the throat
- The jaw and neck, felt externally for lumps
Why early detection matters
The original guide cites the Canadian Cancer Society’s five-year net survival figure of 64% for head and neck cancers, a broad category that includes oral cancers. Outcomes vary with the cancer’s site and stage; this figure is not an individual prognosis.
Oral cancer is often diagnosed after it has advanced. Finding a concerning tissue change earlier can improve treatment options and may allow less extensive treatment. That is the purpose of routine screening: to notice changes before they become harder to manage.
Many people do not realise that a dental visit includes an oral cancer check. Others wait until something hurts or becomes visibly troublesome. Because a clinician can examine many oral tissues directly, routine visits offer an important opportunity to notice a change. Screening still cannot find or rule out every cancer.
Warning signs of oral cancer
Early changes can cause little or no pain. Signs worth having checked include the following. Many have non-cancerous causes, but symptoms alone cannot establish what is happening. Arrange an assessment for a change that persists for more than two weeks, and sooner if it is concerning.
- A white patch that cannot be wiped away, sometimes called leukoplakia
- A red patch, sometimes called erythroplakia; persistent red patches need particular attention
- A sore or ulcer that has not healed within two weeks
- A lump, thickening or rough spot on the lips, gums or inside the cheek
- A 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 the mouth, face or neck
- Unexplained bleeding in the mouth
- Loose teeth without an obvious dental cause
- A new or persistent lump in the neck
Who is at highest risk?
Oral cancer can occur in anyone. The following factors increase risk, but having none of them does not make screening unnecessary.
Tobacco use
Smoking cigarettes, cigars or pipes and using smokeless tobacco expose the tissues of the mouth to carcinogens. Tobacco is an important risk factor for oral cancer.
Heavy alcohol use
Alcohol increases risk, and using tobacco together with heavy alcohol consumption raises it further. Tell your clinician about both so your advice reflects your circumstances.
HPV infection
Human papillomavirus, particularly HPV-16, is associated with oropharyngeal cancers of the tonsils and base of the tongue. These cancers can develop in people who have never smoked.
Sun exposure
Cumulative ultraviolet exposure increases the risk of lip cancer, especially on the lower lip. Sun protection belongs in your oral-health conversation too.
Age and sex
Risk increases with age and is greater after 50. Men are diagnosed more often than women, but anyone can be affected. Routine assessment remains relevant even without an obvious risk factor.
What happens during the screening?
The process is non-invasive. Your dentist combines a visual examination with gentle palpation, using gloved hands to feel tissues. It is usually brief and does not require special preparation. Tell the team if an area is tender.
Visual examination
Under good lighting, your dentist checks for lesions, patches and differences in the colour, texture or size of oral tissues.
Palpation
Your dentist feels the jaw, floor of the mouth, tongue and sides of the neck for lumps, thickening, swelling or unusual firmness.
What happens if something looks suspicious?
A screening is not a diagnosis. Your dentist explains what was found and whether monitoring, additional testing or specialist referral is appropriate.
- A follow-up in one to two weeks may be appropriate for selected changes expected to heal, such as an apparently benign ulcer. A suspicious lesion may need prompt referral rather than observation.
- Cytology uses a brush or swab to collect cells for laboratory assessment. It does not replace a biopsy when one is indicated.
- A biopsy removes a small tissue sample for pathological examination. Tissue analysis may be needed to confirm or rule out cancer.
Referral and results
The size and location of the lesion help determine who should assess it and perform any biopsy. Your dentist may refer you to an oral surgeon or another specialist. Ask who will contact you with the results and when; laboratory turnaround varies, so do not assume a fixed three-to-five-day result.
How often should you get screened?
Screening is part of routine dental examinations. Many adults attend about every six months, but your recall schedule should reflect your oral health and individual risk rather than a fixed interval for everyone.
Tobacco use, heavy alcohol consumption, a relevant HPV history or a previous concerning finding may affect monitoring. Discuss a schedule with your dentist, and do not wait for a recall appointment if a new change concerns you.
Can you check your mouth at home?
A regular self-check can help you notice changes between appointments. Some healthcare providers suggest doing it monthly. It is not a substitute for professional screening and cannot diagnose or rule out cancer.
- Face and neck: in a mirror, look for new swelling, lumps or asymmetry. Gently feel along the jaw and sides of the neck.
- Lips: pull each lip away from the teeth. Look for sores, discolouration or unusual patches and gently feel for lumps.
- Cheeks: gently pull each cheek outward and look at its inner surface for red or white areas, thickening or tenderness.
- Gums: look along the gumline on the cheek and tongue sides for a change in appearance.
- Tongue: check the top, tip and sides, then lift the tip towards the roof of the mouth to see the underside.
- Roof of the mouth: tilt your head back and look for discolouration or ulcers.
- Floor of the mouth: lift your tongue and notice any new swelling, tenderness or lump.
When to call
If something looks or feels different, or a sore has not healed after two weeks, call your dentist. You do not need to wait for the next scheduled visit, and a change does not need to hurt before it deserves attention.
