27 July World Head and Neck Cancer Day: Watch Symptoms Lasting More Than 3 Weeks
In this article
Speaking, swallowing, tasting, breathing and expressing ourselves through our faces… The head and neck bring essential daily functions into a narrow anatomical space. Cancer here therefore affects more than survival; voice, nutrition, appearance, social life and psychological well-being are also part of the disease and treatment.
Each year, 27 Julyis observed as World Head and Neck Cancer Day. Its main message is not fear, but not normalizing changes that persist: a nonhealing mouth sore, persistent hoarseness or painless neck swelling lasting weeks should be assessed.
The message to remember is: One symptom, three weeks, one examination.
Published by IARC in July 2026, GLOBOCAN 2024 estimates report annually, across all cancers, 20.636.441 new diagnoses. Combining lip-oral cavity, oropharyngeal, nasopharyngeal, hypopharyngeal, laryngeal and salivary gland cancers yields 1.020.472 new diagnoses and 475.065 deaths . This accounts for %4,9of all new cancers, approximately one in every 20.
The International Federation of Head and Neck Oncologic Societies (IFHNOS) declared 27 July, in 2014 at its 5. World Congress held in New York, World Head and Neck Cancer Day. The aim was to explain symptoms and prevention, encourage early consultation and strengthen multidisciplinary professional cooperation.
It is an umbrella term covering neighboring cancers with different biology and treatment:
- Lip and oral cavity: Front of the tongue, floor of the mouth, gums, inner cheeks and hard palate
- Oropharynx: Tonsils, tongue base and soft palate
- Nasopharynx: The area behind the nose
- Hypopharynx: Lower pharynx
- Larynx: The voice box containing the vocal cords
- Nose and paranasal sinuses
- Salivary glands
Brain, eye, thyroid, esophageal and head-neck skin cancers are anatomically in this region but are not generally classified as classic head-neck cancers.
Most classic head-neck cancers develop from flat cells lining the mouth, throat and larynx and are squamous cell carcinomas. Salivary gland and sinus tumors can have very different cellular subtypes. The diagnosis “head and neck cancer” alone therefore does not suffice for treatment planning; the primary site, pathological subtype, stage and biomarkers must all be known.
The European Head and Neck Society's “One for Three” awareness approach is a practical reminder encouraging early consultation. It does not mean nothing should be done before three weeks. A rapidly growing mass, significant bleeding, breathing difficulty or inability even to swallow saliva means do not wait.
Symptoms depend on the primary site. The most important shared feature is persistence, progression or one-sidedness or association with a visible sore or mass.
- A mouth or lip sore not healing in three weeks
- A white or red patch that cannot be wiped away
- Hardness/mass on the tongue, gum or inner cheek
- Unexplained oral bleeding or pain
- Tongue numbness or restricted movement
- Unexplained loose teeth; dentures no longer fitting
- Persistent hoarseness or voice changes
- Persistent sore throat
- Pain or difficulty swallowing
- A stuck or foreign-body sensation in the throat
- Prolonged cough; blood in saliva or phlegm
- One-sided ear pain without visible ear disease
- Persistent neck swelling, painful or painless
- A progressively enlarging lymph node
- A mass below the jaw or at its angle
- New restriction in neck movement
Especially important: HPV-related oropharyngeal cancer may first appear, without an obvious mouth or throat sore, as a painless neck mass at presentation.
- Persistent one-sided nasal blockage
- Recurrent nosebleeds or bloody discharge
- Sinus complaints not improving despite treatment
- One-sided hearing loss, ear fullness or ringing
- Facial numbness, swelling or pain
- Double vision or swelling around the eye
- A mass in front of the ear, under the jaw or in the mouth floor
- New weakness on one side of the face
- Persistent facial, jaw or neck numbness
- Pain or restricted jaw movement
- Unexplained weight loss
- Reduced food intake and weakness
- Difficulty breathing or noisy breathing
- Persistent bad breath unexplained by oral hygiene
Mouth ulcers, infections, reflux, voice overuse, dental disease and benign nodules can cause the same complaints. A symptom list cannot distinguish them. Concern arises not from a symptom alone, but its persistence, progression or unexplained nature.
Cigarettes, cigars, pipes, hookah and smokeless tobacco are not safe. Tobacco is among the strongest preventable causes particularly of oral, hypopharyngeal and laryngeal cancers. Passive exposure is not risk-free either.
Ethanol in alcoholic drinks and its metabolite acetaldehyde are carcinogenic. Risk increases with consumption. When tobacco and alcohol are combined, harm may exceed a simple sum.
Persistent HPV-16 infection is particularly an important cause of oropharyngeal cancers involving the tonsils and tongue base. HPV's role differs across head-neck sites.
HPV is extremely common, and approximately of 10 infections, 9 are controlled within two years by the immune system. Cancer usually follows a high-risk type's persistent infection lasting years . An HPV-positive head-neck cancer diagnosis does not establish when or from whom infection was acquired; it is not evidence of recent transmission or infidelity.
HPV-related oropharyngeal cancer also occurs in never-smokers. These tumors generally respond better than HPV-negative tumors, but that does not mean the disease is trivial or treatment can be reduced. Treatment intensity changes only within a clinical trial or by an expert team's decision.
Other risk factors
| Risk or exposure | More commonly associated site | What you should know |
|---|---|---|
| Epstein–Barr virus (EBV) | Nasopharynx | May contribute alongside geography, genetic ancestry and environmental factors. |
| Areca nut/betel and smokeless tobacco | Lip and oral cavity | Create a major cancer burden particularly in South and Southeast Asia; “smokeless” does not mean safe. |
| Sun/UV exposure | Lip | May increase lower-lip cancer risk particularly in people working outdoors for long periods. |
| Wood and nickel dust, formaldehyde | Nose and paranasal sinuses | Appropriate workplace precautions matter in furniture, wood, leather and certain industries. |
| Previous radiation exposure | Particularly salivary glands | Risk depends on dose, area and time since exposure. |
| Immunosuppression and rare genetic syndromes | Various sites | Rare conditions such as Fanconi anemia may substantially increase risk at a young age. |
- Quit tobacco: Changing product form is not prevention. Quitting reduces cardiovascular and lung disease risk as well as head-neck cancer.
- Reduce or avoid alcohol: For cancer risk, “the less, the better” applies.
- Consider HPV vaccination for girls and boys: Vaccination protects most before viral exposure, but may also be considered in adults according to age and previous vaccination. Schedule and dose decisions should be made with a physician.
- Do not neglect regular oral and dental examinations: A dentist may detect visible oral lesions during routine examination. This alone is not a screening program for all head-neck cancers.
- Protect against occupational and sun exposure: Appropriate masks/ventilation, workplace precautions and sunscreen for lips matter.
Unlike cervical HPV testing or mammography, no standard head-neck cancer screening test is recommended for all asymptomatic people. Oral HPV swabs are also unsuitable for routine cancer screening. The most realistic approach is therefore; risk reduction, HPV vaccination, routine oral examination and prompt assessment of persistent symptoms.
A suspicious symptom prompts detailed history and examination of the mouth, tongue, tonsils, nose, throat and neck. If necessary, an ENT specialist uses a thin flexible camera to view the nose, nasopharynx, pharynx and larynx.
- Clinical examination: Mouth and neck examination; assessment of cranial nerves, voice and swallowing
- Endoscopy: Nasopharyngolaryngoscopy to examine difficult-to-see areas
- Imaging: Ultrasound, computed tomography, MR or PET-BT according to tumor site
- Biopsy: The fundamental procedure confirming diagnosis; needle biopsy is often preferred for a neck mass
- Biomarkers: p16/HPV assessment in oropharyngeal squamous cancer; EBV-related tests in selected nasopharyngeal cases
Normal blood values do not prove absence of head-neck cancer. Imaging can strengthen suspicion, but definitive diagnosis usually requires a tissue sample for pathological examination to be obtained.
Older awareness materials often used one figure, such as “five-year survival is %90 with early diagnosis”. This is misleading. Survival varies markedly with primary site, stage, HPV status, biological subtype, general health and treatment access. Lip and hypopharyngeal cancers, or HPV-positive oropharyngeal and tobacco-related laryngeal cancers, cannot be described by the same rate.
A smaller, localized tumor often means less extensive surgery or a smaller treatment field. This may improve not only disease control but also the chance of preserving speech, swallowing, chewing, taste, breathing and appearance for the patient.
Head-neck cancer treatment therefore brings together ENT/head-neck surgery, medical oncology, radiation oncology, pathology, radiology, nuclear medicine, dentistry, nutrition, speech-swallowing therapy, physiotherapy and psychosocial support in an experienced multidisciplinary team that should plan treatment.
HPV-related oropharyngeal, EBV-related nasopharyngeal and salivary gland cancers can occur in nonsmokers.
Even in nonsmokers, a neck mass or voice change lasting more than three weeks needs assessment.
Mouth ulcers, trauma, fungal infections and other benign conditions are much more common. Nonhealing, hardness, bleeding and growth raise suspicion.
Definitively classifying a lesion using only a photograph or symptoms is inappropriate.
HPV may remain silent for years. Positivity does not reveal infection timing or source.
Vaccination aims to reduce not only cervical cancer but other HPV-related cancers too.
Türkiye needs to continue fighting tobacco, explain alcohol's cancer risk clearly and view HPV vaccination as a cancer prevention strategy covering girls and boys while accelerating referrals among dentists, family physicians and ENT specialists.
Another critical goal is not observing painless neck masses for months as “a chill” or “a lymph node”. An unexplained, persistent adult neck mass, particularly one-sided, deserves specialist assessment.
Delay can allow not only tumor growth but fewer options preserving voice, swallowing and appearance.
Are tobacco cessation, reduced alcohol exposure and HPV vaccination. These also protect against many other cancers and chronic diseases.
No single symptom or statistic describes every head-neck cancer. Statements such as “%90 at early stage” or “every mouth sore is cancer” obscure scientific diversity.
Seek examination for mouth sores, hoarseness, swallowing problems, one-sided nasal symptoms or neck masses lasting more than three weeks. Do not wait three weeks for rapidly progressing or breathing-related symptoms.
Tests such as circulating tumor DNA in HPV-related cancers offer promise for early diagnosis and recurrence monitoring. They are not standard asymptomatic population screening today; technological promise does not yet replace examination and biopsy.

Editor's note: This content provides general information, not personal diagnosis, screening or treatment advice. Because head-neck cancers encompass different sites and histological subtypes, global case totals vary with definitions. The article's 1.020.472 new diagnoses, 475.065 deaths and %4,9 sharewere obtained by combining the lip-oral cavity, oropharyngeal, nasopharyngeal, hypopharyngeal, laryngeal, paranasal sinus and salivary gland cancers reported separately in IARC GLOBOCAN 2024; this is not a separate IARC “total head-neck cancer” category. “One symptom–three weeks” is an early-consultation rule, not a cancer diagnosis or reason to wait with urgent symptoms such as a rapidly growing mass, significant bleeding, breathing difficulty or inability to swallow saliva. Most symptoms have noncancer causes; definitive diagnosis requires appropriate clinical assessment and biopsy when needed. HPV vaccine age, dose and eligibility vary with national programs and personal medical circumstances. Consult your assessing physician for every health decision.
