Cancer of the mouth and oropharynx can cause the following symptoms, but they can also be due to other medical conditions.
It is important to see your GP If you have any of these symptoms.
Ulcers that do not heal
A broken area in the lining of the mouth (ulcer) that will not heal is a common symptom of mouth cancer.
Pain in your mouth
Pain, discomfort or swelling in your mouth that doesn't go away is the other most common symptom of mouth cancer.
Red or white patches in the mouth or throat
An abnormal looking patch could be a sign of cancer or pre cancerous changes:
- White patches are called leukoplakia.
- Red patches are called erythroplakia.
These patches are not cancer, but if left untreated they may lead to cancer.
Red and white patches in the mouth can also be caused by a fungal infection called thrush. The white patches usually rub off, leaving a sore red patch underneath. If you have anti fungal treatment, and the patches go away, they are not related to cancer.
Mouth cancer can cause pain or a burning sensation when chewing and swallowing food. Or you might feel like your food is sticking in your throat. Difficulty swallowing can also be caused by a narrowing of the food pipe (oesophagus).
Cancer in your mouth or throat can affect your voice. Your voice might sound different. It may be quieter, husky, or sound as if you have a cold all the time. Or you might slur some of your words, or have trouble with pronouncing some sounds.
A lump in your neck
You may have a lump in your neck caused by an enlarged lymph node. Swelling in one or more lymph nodes in the neck is a common symptom of mouth and oropharyngeal cancer.
A hot red painful lump usually means an infection, rather than a cancer. Lumps that come and go are not usually due to cancer. Cancer usually forms a lump that slowly gets bigger.
Weight loss is a common symptom of many different types of cancer. Mouth and oropharyngeal cancer can make it painful to eat and difficult to swallow. This might cause weight loss.
Extreme weight loss (when you are not dieting) can be a sign of advanced cancer.
Most people have bad breath at some point in their life and it is not cancer. But if you have cancer, bad breath might be worse and happen more often.
These can include one or more of the following:
- a lump or thickening of your lip
- a lump in your mouth or throat
- unusual bleeding or numbness in your mouth
- loose teeth for no clear reason
- difficulty moving your jaw
- a sore throat that does not get better after a few days
- pain in your ear that does not get better in a few days
When to see your doctor
- an ulcer in your mouth that will not heal
- pain or discomfort in the mouth that will not go away
- symptoms that are unusual for you
- symptoms that don't go away
Your symptoms are unlikely to be cancer but it is important to get them checked by a doctor.
