Somewhere in the middle of your checkup, your hygienist or dentist asks you to stick out your tongue, moves it gently to one side with a piece of gauze, then feels along your jaw and under your chin. It takes about two minutes. Most patients assume it is part of getting a good look at the back teeth.
It is not. That is an oral cancer screening, and it is one of the quietest, most valuable things that happens at a routine visit.
Why it gets its own two minutes
More than fifty thousand people in the United States are diagnosed with oral or throat cancer each year, and the survival numbers for it are stubbornly worse than they should be. The reason is almost entirely about timing. When these cancers are found while they are still small and local, outcomes are generally very good. When they are found after they have spread to the lymph nodes in the neck, they are far harder to treat.
The catch is that early oral cancer is usually painless. There is no toothache to send you in. A sore spot that does not hurt is a sore spot most people never mention, and by the time it does hurt, it is no longer early.
That is the whole argument for screening at every visit rather than waiting for a symptom. You are already in the chair twice a year. It costs two minutes.
What we are actually looking at
The exam is visual and tactile, and it covers more than teeth and gums.
We look at the tongue, including the sides and the underside, which is where a surprising share of lesions turn up and which is exactly the area you cannot see in a bathroom mirror. We look at the floor of the mouth, the roof, the inside of the cheeks and lips, and the tissue at the back of the throat. Then we feel along the jawline, under the chin, and down the sides of the neck for lymph nodes that feel enlarged or firm.
The findings that get our attention are:
A sore that has not healed in two to three weeks. Ordinary mouth injuries heal quickly. Something that is still there a month later is worth investigating.
A white or red patch that will not wipe away. Red patches in particular deserve a closer look.
A lump, thickening, or rough patch in tissue that should feel soft and even, especially if it is on one side only.
A change in how things work. Persistent hoarseness, a feeling that something is caught in your throat, numbness in the lip or tongue, difficulty swallowing or moving the jaw, or a change in the way your teeth fit together that has no obvious cause.
Most of what we find turns out to be harmless. Cheek bites, irritation from a denture edge, a canker sore, a spot rubbed raw by a sharp filling. Finding those and fixing them is useful too. But we look at everything the same way, because the only way to catch the rare serious one is to take all of them seriously.
The risk factors, including one specific to Florida
Tobacco in any form remains the largest risk factor, and chewing tobacco and snuff carry particular risk for the gums and cheek where the product sits. Heavy alcohol use is an independent risk, and combining the two multiplies the risk rather than adding to it.
HPV has changed the picture over the last two decades. HPV-related cancers tend to appear at the back of the mouth and throat, often in people who never smoked, and they frequently show up in patients younger than the classic risk profile would suggest. This is a real part of why we screen every adult rather than only the ones with an obvious history.
And then there is the one that matters especially here. Lip cancer is strongly associated with cumulative sun exposure, and Lake County gives people plenty of it. If you golf, fish, boat, garden, or spend afternoons on the pickleball court, your lower lip has taken decades of direct sun that the rest of your face may have been shielded from by a hat brim. Lip balm with SPF is genuinely preventive care, and it is the easiest recommendation we give all week.
Age is a factor as well, which is one more reason consistent routine exams and cleanings matter more, not less, as you get older.
What happens if we see something
Usually the first step is simply to watch it. If a spot has a plausible innocent explanation, such as a rough denture edge or a habit of biting the same cheek, we address the cause and ask you back in two weeks to look again. Most things resolve, and that is the end of it.
If it is still there at the recheck, or if it looked concerning to begin with, we refer you to an oral surgeon or an ear, nose, and throat specialist for a biopsy. A biopsy is a small procedure, and it is the only thing that gives a definite answer. Getting referred is not a diagnosis, and we would much rather send ten people who turn out to be fine than talk one person out of going.
What to check on your own
Once a month, in good light, take a look. Pull your lower lip down and your upper lip up and look at the tissue inside. Pull each cheek out with a finger. Stick your tongue out, then lift it and look underneath. Run a finger along your jaw and neck. You are not diagnosing anything. You are just learning what your mouth normally looks like, so that a change registers as a change.
Then tell us about anything that has been there for more than two weeks, even if it does not hurt. Especially if it does not hurt.
We screen every adult patient at every exam, and we are always glad to take a proper look at something you noticed. We see patients from Leesburg, The Villages, Fruitland Park, Eustis, Tavares, and across Lake County. Schedule a visit or call us at (352) 326-4404.
