A mouth ulcer that is not healing. A small lump in the neck. A change in your voice. Difficulty swallowing. Blood coming from the mouth or nose.
It is easy to think:
“It is probably nothing. I will wait for a few more days.”
Most of the time, these symptoms are caused by conditions other than cancer. But when a symptom does not go away, repeatedly returns or gradually becomes worse , I would rather have you get it checked than continue waiting.
Head and neck cancers can develop in the mouth, tongue, gums, throat, tonsils, voice box, nose, sinuses and salivary glands .
The important message is simple:
Do not panic about every symptom—but do not ignore a persistent one either.
1. Doctor, I have a mouth ulcer. Could it be cancer?
Most mouth ulcers are not cancer and heal normally.
However, please consult a doctor or dentist if you have:
An ulcer or sore that does not heal
An ulcer that is gradually becoming larger
Repeated bleeding from the area
Persistent pain or burning
A growth, lump or thickened area inside the mouth
Do not wait for an ulcer to become very large or painful before showing it to someone.
Cancer does not always cause pain in its early stages.
2. I have a white or red patch inside my mouth. Should I worry?
A persistent white, red or mixed red-and-white patch inside the mouth deserves examination, particularly if you use tobacco or areca-nut products.
Occasionally look at your:
Tongue
Gums
Inner cheeks
Floor of the mouth
Other visible areas inside your mouth
Do not try to decide whether a patch is harmless or cancerous by comparing it with photographs on the internet.
Let a doctor or dentist examine it.
3. My mouth is opening less than before. Is that important?
Yes, particularly if the reduction is gradually increasing .
You may first notice difficulty while:
Eating
Brushing your teeth
Taking a large bite
Trying to place your fingers between your teeth
This is particularly important if you regularly use gutkha, mawa, tobacco or supari/areca nut .
Burning while eating spicy food, stiffness inside the mouth and progressively decreasing mouth opening can occur with conditions associated with areca-nut and tobacco use.
Do not simply accept decreasing mouth opening as a normal consequence of chewing these products. Get examined.
4. I have noticed a lump in my neck. Could it be cancer?
There are many causes of neck swellings, including infections, and not every neck lump is cancer.
However, a persistent or enlarging neck lump—particularly in an adult—needs medical evaluation.
Sometimes cancers arising in areas such as the tonsil or base of the tongue may first become noticeable because of a lump in the neck.
Importantly, the lump may be painless .
Painless does not automatically mean harmless.
5. Food feels stuck when I swallow. When should I get checked?
Persistent or progressively worsening swallowing problems should be investigated.
Please pay attention if:
Food seems to get stuck
Swallowing is becoming progressively difficult
Swallowing is painful
You repeatedly cough or choke while eating
You constantly feel as though something is stuck in your throat
Do not wait until swallowing becomes extremely difficult before seeking medical attention.
6. My voice has become hoarse. How long should I wait?
Temporary hoarseness during a cold or throat infection is common.
However, if your voice remains persistently hoarse or noticeably different for weeks , it should be examined—particularly if you smoke or use tobacco.
The larynx, or voice box , is one of the areas where head and neck cancer can develop.
7. Why does unexplained ear pain matter?
Sometimes a problem originating in the throat can be experienced as pain in the ear.
Please consult a doctor if you develop:
Persistent throat pain
Persistent pain while swallowing
Unexplained pain in one ear
Ear pain together with swallowing difficulty
Ear pain associated with a neck swelling
These symptoms do not automatically mean cancer , but persistent unexplained symptoms deserve evaluation.
8. Is bleeding from the mouth or nose a warning sign?
Occasional bleeding can have many non-cancerous causes.
However, repeated or unexplained bleeding should not simply be ignored.
This includes:
Bleeding from the mouth
Blood in saliva
Recurrent nosebleeds
Bleeding from a mouth ulcer or growth
It becomes particularly important when bleeding occurs together with another persistent symptom.
Significant or continuing bleeding requires prompt medical attention.
9. Can persistent nasal or sinus problems be related to cancer?
Most nasal and sinus symptoms are not caused by cancer .
Cancers of the nose and sinuses are much less common than many other head and neck cancers.
However, warning symptoms can include:
Persistent nasal blockage, particularly on one side
Repeated nosebleeds
Sinus symptoms that do not improve despite appropriate treatment
Facial pain or swelling
Swelling around the eye
Persistent unexplained upper-tooth pain
Persistent or unusual symptoms should be examined rather than repeatedly self-treated.
10. Is unexplained weight loss important?
Weight loss has many possible causes and does not automatically indicate cancer.
However, unintentional weight loss deserves attention, particularly when it occurs together with:
Difficulty swallowing
Persistent mouth or throat symptoms
A neck lump
Reduced ability to eat normally
Discuss unexplained weight loss with your doctor.
11. Who is at higher risk of head and neck cancer?
Having a risk factor does not mean that you will definitely develop cancer.
Similarly, people without obvious risk factors can still develop head and neck cancers.
However, several factors clearly increase risk.
Tobacco
This includes:
Cigarettes
Bidis
Cigars
Hookah
Chewing tobacco
Gutkha
Mawa
Khaini
Other smokeless tobacco products
Both smoked and smokeless tobacco can increase the risk of head and neck cancers.
There is no safe tobacco product for your mouth and throat.
Alcohol
Alcohol increases the risk of several cancers of the mouth, throat and voice box.
Using both tobacco and alcohol increases the risk further.
Changing from one type of alcoholic beverage to another does not eliminate the cancer risk associated with alcohol.
Supari/areca nut
Do not assume something is harmless simply because it is chewed rather than smoked.
If you regularly use supari, gutkha, mawa or similar products and develop burning while eating spicy food, stiffness inside your mouth or progressively reduced mouth opening, please get examined.
HPV
Human papillomavirus, or HPV , is associated with some cancers arising in the tonsils and base of the tongue .
This is important because HPV-associated throat cancers can occur even in people without the traditional history of tobacco use.
Other risk factors
Depending on the particular cancer, risk may also be influenced by:
Increasing age
Ultraviolet exposure, particularly for lip cancer
Certain occupational exposures
Epstein-Barr virus infection in particular cancers
12. How long should I wait before seeing a doctor?
You do not need to assume cancer every time you develop a mouth ulcer, sore throat or temporary change in your voice.
As a practical rule, arrange an examination if a suspicious symptom:
Persists for around 2–3 weeks
Repeatedly returns
Progressively worsens
Has no satisfactory explanation
But do not wait 2–3 weeks when something is clearly concerning.
Seek earlier medical attention for:
An enlarging neck lump
Significant or persistent bleeding
Increasing difficulty swallowing
Difficulty breathing
Rapidly increasing swelling
Severe or rapidly worsening symptoms
Depending on the problem, you may need evaluation by a dentist, ENT specialist, oral surgeon, head-and-neck surgeon or oncologist .
13. If it does not hurt, can I safely ignore it?
No.
Pain is not required for cancer to be present.
A painless neck lump, painless mouth lesion or painless persistent patch may still require investigation.
Do not use absence of pain as your test for whether something is serious.
14. I use tobacco, but I find it very difficult to stop. What should I do?
Tell your doctor.
Do not hide tobacco use because you are worried that you will be judged.
Nicotine dependence is an addiction, and treatment is available. You do not necessarily have to quit through willpower alone.
Treatment can include:
Behavioural counselling: identifying triggers, planning how to quit and developing strategies for managing cravings.
Nicotine-replacement therapy: options such as nicotine gum may be appropriate for some people.
Tobacco-cessation services: dedicated centres can provide counselling and, where appropriate, medication to help with cessation.
If you have tried to stop before and restarted, you can try again. Tobacco dependence frequently requires repeated attempts and continued support .
15. What is the one message I should remember?
Do not wait for a suspicious symptom to become severe before showing it to a doctor.
Do not wait for a mouth lesion to become very large or painful.
Do not wait until swallowing becomes extremely difficult.
Do not wait until a small neck swelling becomes a large one.
And do not avoid consultation because you are frightened that it might be cancer.
Many of these symptoms will ultimately have a non-cancerous explanation .
But if cancer is present, earlier diagnosis generally gives us more treatment options and a better opportunity to treat it effectively .
So, if something in your mouth, throat, neck, voice, nose or swallowing does not feel right and is not going away, get it examined.
Getting it checked does not mean that you have cancer.
It means that you are taking the symptom seriously.
