Signs and Symptoms of Head and Neck Cancer
A sore throat that lingers past three weeks isn't something most people think twice about. It's the lingering part that changes things. The signs and symptoms of head and neck cancer often hide inside everyday complaints, a hoarse voice, a lump you assume is a swollen gland, a mouth sore that won't close up, which is exactly why they're missed until later than they should be. This page walks through what to watch for, broken down by where in the head and neck it shows up, so you know what's worth a same-week appointment.

The most common signs and symptoms of head and neck cancer include a persistent sore throat, hoarseness lasting more than three weeks, a lump in the neck, mouth sores that don't heal, and difficulty swallowing. Symptoms vary by the exact site affected, throat, mouth, sinuses, salivary glands, or neck, and any that persist beyond two to three weeks warrant an ENT evaluation, typically starting with a physical exam and endoscopy.
What Is Head and Neck Cancer?
Head and neck cancer is an umbrella term for cancers that start in the mouth, throat, voice box, sinuses, salivary glands, or the lymph nodes of the neck. In India, oral cavity cancers alone rank among the most commonly diagnosed cancers in men, driven largely by tobacco and betel nut use.
What makes these cancers tricky to catch early is overlap. A sore throat, hoarse voice, or mouth ulcer is common and usually nothing. It's the pattern, how long it lasts and whether it's getting worse, that separates a cancer worth investigating from a cold that will pass on its own.
Early Signs of Head and Neck Cancer: What to Watch For
No single symptom confirms anything on its own. It's persistence past two to three weeks that turns an ordinary complaint into one worth checking.
Pain & Physical Symptoms
- A sore throat that doesn't improve after three weeks, with or without a cold
- Persistent ear pain on one side, without any sign of an ear infection
- A hoarse or raspy voice that lasts longer than three weeks
- Pain or difficulty swallowing that keeps returning at meals
- Numbness or persistent pain in the face, jaw, or upper teeth for no clear reason
Visible & Functional Changes
- A lump or swelling in the neck that doesn't go down after a couple of weeks
- A mouth or tongue sore that hasn't healed within two weeks
- White or red patches on the gums, tongue, or lining of the mouth
- Unexplained bleeding or blood-tinged saliva without an obvious cause
- Unintended weight loss alongside any of the symptoms above
Symptoms of Head and Neck Cancer by Site
Head and neck cancer isn't one condition in one place. Where it starts decides which symptoms show up first, and how easy they are to dismiss.
Throat & Larynx (Voice Box)
Hoarseness that outlasts three weeks is the earliest and most reliable clue here. As it progresses, swallowing pain, a persistent cough, or a sensation of something stuck in the throat can follow.
Oral Cavity (Mouth & Tongue)
A mouth sore or ulcer that hasn't healed in two weeks is the classic warning sign, often alongside white or red patches, loose teeth with no dental cause, or pain when chewing.
Nasal Cavity & Sinuses
Symptoms mimic chronic sinusitis: one-sided nasal blockage, frequent nosebleeds, or facial pain and numbness that doesn't respond to the usual sinus treatments.
Salivary Glands
A firm, painless swelling near the jaw, cheek, or under the tongue is the most common sign. Facial weakness on one side can appear if a nearby nerve is affected.
Neck & Lymph Nodes
A painless lump in the neck that persists beyond two to three weeks, especially in someone over 40 with a smoking or tobacco history, is one of the most common ways head and neck cancer first gets noticed.
Seek Care Immediately If
Breathing or swallowing becomes suddenly difficult
A neck lump grows rapidly over days rather than weeks
Bleeding from the mouth, nose, or throat is heavy or won't stop
Sudden facial weakness or numbness develops on one side
Severe, unrelenting pain appears alongside any of the symptoms above
These signs need prompt medical attention, the same day if possible, not a wait-and-see approach. Most causes turn out to be infection or inflammation, but only an exam and imaging can confirm that safely.
How Head and Neck Cancer Symptoms Are Diagnosed
- 01
Clinical & ENT Examination
A doctor examines the mouth, throat, and neck directly, checking for lumps, sores, or asymmetry that point toward where the problem sits.
- 02
Endoscopy & Imaging
A thin, flexible scope lets the doctor see areas not visible from the outside, like the voice box or throat. CT, MRI, or PET scans then map the extent of any abnormal tissue.
- 03
Biopsy & Confirmation
A tissue sample confirms whether cells are cancerous and, if so, whether HPV is involved, a result that shapes every treatment decision that follows.
What Increases the Risk of Head and Neck Cancer Symptoms?
A handful of exposures account for the large majority of cases, which is what makes this cancer group unusually preventable.
Tobacco & Betel Nut Use
Smoking, chewing tobacco, and betel nut (gutkha, paan) use together account for the majority of head and neck cancers diagnosed in India, and the risk climbs sharply when combined with alcohol.
Alcohol Consumption
Heavy, regular alcohol use raises risk on its own and multiplies the risk from tobacco when both are present, rather than simply adding to it.
HPV Infection
Human papillomavirus, particularly HPV-16, is now a leading cause of oropharyngeal (throat) cancers in people with no tobacco or alcohol history, especially younger adults.
Age, Sex & Prior Radiation
Risk rises after age 40 and is higher in men. Prior radiation exposure to the head or neck, even years earlier, also raises long-term risk.
Types of Head and Neck Cancer
Classification comes down to where the cancer starts and, increasingly, whether HPV is involved.
By Site
- Oral cavity cancers start in the lips, tongue, gums, or lining of the mouth and are the most common type in India.
- Pharyngeal cancers arise in the throat and are named by section: nasopharyngeal (the nasopharynx, the area behind the nose), oropharyngeal (the oropharynx, the area behind the mouth), and hypopharyngeal (the hypopharynx, the lower throat used for swallowing).
- Laryngeal cancers begin in the voice box and often announce themselves early through hoarseness, since the vocal cords are affected quickly.
- Salivary gland and nasal or paranasal sinus cancers are less common but follow the same principle: symptoms trace back to whatever structure the tumor started in.
By Cause
- HPV-positive oropharyngeal cancers tend to occur in younger, otherwise healthy people and generally respond better to treatment than HPV-negative disease.
- HPV-negative cancers are more closely tied to tobacco and alcohol use and are more common in older adults with a heavy smoking history.
What Happens After a Head and Neck Cancer Diagnosis?
Treatment depends on the exact site, stage, and HPV status, not a single fixed protocol.
Surgery
Removing the tumor and, when needed, nearby lymph nodes, often the first step for cancers that are accessible and localized.
Radiation Therapy
Targets the tumor site with precise beams, used alone for smaller cancers or combined with surgery and chemotherapy for larger ones.
Chemotherapy & Targeted Therapy
Used alongside radiation for more advanced disease, or to shrink a tumor before surgery becomes an option.
This is a starting map, not a treatment plan. The right combination depends on details only an in-person consultation and imaging review can settle.
Questions Patients Ask Us
The earliest signs are often a sore throat or hoarse voice lasting more than three weeks, a mouth sore that hasn't healed in two weeks, or a painless lump in the neck.
A sore throat that hasn't improved after three weeks, especially without other cold symptoms, is worth an ENT evaluation. Most sore throats clear up well before that point.
It can be, particularly if it's painless, firm, and persists beyond two to three weeks. Most neck lumps turn out to be reactive lymph nodes from infection, but persistence is what warrants a check.
No, most hoarseness comes from a cold, overuse, or acid reflux and clears within days. Hoarseness lasting more than three weeks, without an obvious cause, is what needs an ENT look.
A mouth ulcer that hasn't healed within two weeks is one of the more reliable early signs of oral cancer, especially in someone with a tobacco or betel nut history.
Yes, persistent one-sided ear pain with no sign of an ear infection can be referred pain from a tumor in the throat or voice box, since these areas share nerve pathways with the ear.
Recurrence often shows up as the same symptoms that led to the original diagnosis, a new lump, worsening pain, or difficulty swallowing, at or near the original treatment site.
Yes, especially with cancers of the throat or voice box, where it usually builds gradually and gets worse with solid foods before it affects liquids.
Yes, HPV-related oropharyngeal cancer often shows up first as a painless lump in the neck, sometimes with no other symptoms, in people with no smoking or drinking history.
Not Sure If Your Symptoms Need a Specialist?
A second opinion doesn't require a referral or a firm diagnosis, just your existing scans or a description of what you're experiencing. Dr. P. Vijay Karan Reddy reviews cases directly and can tell you within one consultation whether further imaging or a specialist workup makes sense.
