Oral Cancer Screening & Biopsy
There is a particular kind of worry that comes with noticing something in your mouth that has not gone away, and then quietly deciding not to look at it again. Here is the reassuring part: most ulcers and patches turn out to be harmless, the check itself takes a few minutes and does not hurt, and knowing is very much easier than wondering.

What an oral screening actually is
An oral cancer screening is a careful look at the lining of your mouth. Under a good light, the surgeon examines the lips, the tongue including its underside and its edges, the floor of the mouth, the inside of both cheeks, the gums, the palate and the back of the throat, then gently feels the tongue and cheeks and checks the glands in the neck.
That is genuinely all it is. No needle, no dye, no scan, no discomfort. It takes a few minutes, and you are told what was seen before you leave the room.
The mouth is unusual in that it can be examined directly, with nothing more than a light and trained eyes. That is also why the two-week rule exists: an ulcer or patch that has not healed within about two weeks is worth examining, because ordinary causes have usually settled by then.
Screenings here are done by Dr. Nainik Mehta, MDS, Oral & Maxillofacial Surgery, the specialty trained in the surgical assessment of the mouth, jaws and face.
What is worth getting looked at
Please read this list the way it is meant: as a short set of prompts to book an examination, not as a checklist of frightening possibilities. Nothing on this list means you have cancer. Each item simply has ordinary causes that are easy to confirm and worth confirming.
Book a check if…
✓ An ulcer or sore in the mouth has not healed in about two weeks
✓ There is a white, red or mixed patch that you cannot wipe away
✓ A rough, thickened or raised area has appeared in the cheek, gum or tongue
✓ There is a lump in the mouth, lip or neck that stays
✓ Swallowing feels caught, or your voice has changed for more than a few weeks
✓ A numb patch or persistent burning has appeared without an obvious cause
✓ You use tobacco in any form and would simply like a baseline check, even with no symptoms
What usually turns out to be the cause
✓ A cheek or tongue bitten while eating or sleeping
✓ A sharp tooth edge, a broken filling, or a denture rubbing the same spot
✓ A common viral or aphthous ulcer, which comes and goes
✓ A fungal or bacterial infection, which settles with treatment
✓ A harmless anatomical variation someone has simply noticed for the first time
✓ Irritation from a very hot or spicy diet, a medicine, or a mouthwash
The purpose of a screening is not to find something. It is to be able to tell you, with reasons, that there is nothing that needs treating, or, in the small number of cases where there is, to have found it while it is still small and straightforward to deal with.
What happens at the clinic, step by step
A short conversation
How long the ulcer or patch has been there, whether it is changing, whether anything nearby could be rubbing it, your general health and medicines, and any tobacco or alcohol use. This is asked without judgement; it simply changes what the examination looks for.
The examination, a few minutes
A visual and hands-on check of the whole mouth and the glands of the neck under good light, as described above. It does not hurt and needs no preparation from you.
A plain explanation on the same visit
In most cases you are told there and then that what you have is a common, harmless problem, and given its likely cause. If an obvious irritant is present, such as a sharp tooth edge or an ill-fitting denture, it is smoothed or adjusted so the irritation stops, and you return in about two weeks so healing can be confirmed.
A biopsy, only where a closer look is genuinely needed
If an area has not healed as expected, or should be identified rather than watched, a small tissue sample is taken. The area is fully numbed with local anaesthesia, a small piece of tissue is removed, a stitch or two may be placed, and you go home the same day, normally within half an hour. Being advised a biopsy is not a diagnosis; it is how uncertainty is removed.
The result, explained face to face
The sample goes to a laboratory and the report generally takes a few days to about a week. Dr. Nainik Mehta explains it to you in person, plainly, whatever it says. A normal report is stated clearly. Something that needs watching comes with a review schedule. Anything needing treatment comes with an explanation of what and where, plus help arranging onward care, including referral to an oncology team where that is the right step.
The honest answers
Why bother, if most of it is harmless?
Because the mouth is easy to look at, and changes found early are generally far simpler to deal with than changes found late. That is the whole logic of screening: a few minutes of your day against months of quiet worry, with the most likely outcome being that you go home reassured.
How much does it hurt?
The screening does not hurt at all; there is nothing to feel. A biopsy is done fully numbed, so the injection is the only sharp moment. Afterwards the site is tender for a few days, similar to having bitten your cheek, eased by soft food and prescribed medicines. Most people carry on with their day normally.
Should I wait a bit longer and see?
Two weeks is the sensible dividing line. Before that, most ordinary ulcers heal by themselves and waiting is reasonable. After that, an unhealed area deserves a look, and putting it off usually creates far more worry than the appointment takes minutes. If you are unsure which side of the line you are on, message us and ask.
After a biopsy, and looking after your mouth
The first week. Some oozing on day one is normal. Eat soft, cool food, avoid hot, spicy or crunchy items, and do not poke the area with your tongue. Rinse gently as instructed, keep brushing your other teeth normally, and expect tenderness that fades steadily. Stitches either dissolve or come out at a short review visit. Avoid tobacco and alcohol while the site heals; it makes a real difference to how quickly it settles.
Reducing risk in general. The most useful thing anyone can do for the lining of their mouth is to stop tobacco in every form, including gutkha, khaini and pan masala with tobacco, and to keep alcohol modest. Protecting the lips from long sun exposure helps too. If you want help stopping, say so; it is a conversation we are happy to have, without lectures.
Checking your own mouth. Once a month, in good light, look at your tongue including its edges and underside, lift it to see the floor of the mouth, pull each cheek out gently, and look at your gums and palate. You are not trying to diagnose anything, just becoming familiar enough with your own mouth to notice if something new stays for two weeks.

Screening questions, answered straight
Does a mouth ulcer mean cancer?
What actually happens during a screening?
Is a biopsy painful?
How long does the report take, and who explains it?
I chew tobacco or pan masala. Should I get checked even with no symptoms?
The report says my lesion is not cancer. Is that the end of it?
Something in your mouth that has not gone away?
Tell us where it is and roughly how long it has been there. If it sounds like something that will settle on its own, you will be told that too. Either way, a few minutes of checking is better than months of wondering.
