Some of the most common oral cancer symptoms and signs include:
- Persistent mouth sore: A sore in the mouth that does not heal is the most common symptom of oral cancer
- Pain: Persistent mouth pain is another common oral cancer sign
- A lump or thickening in the cheek
- A white or red patch on the gums, tongue, tonsil, or lining of the mouth
- A sore throat or feeling that something is caught in the throat that does not go away
- Difficulty swallowing or chewing
- Difficulty moving the jaw or tongue
- Numbness of the tongue or elsewhere in the mouth
- Jaw swelling that makes dentures hurt or fit poorly
- Loosening of the teeth
- Pain in the teeth or jaw
- Voice changes
- A lump in the neck
- Weight loss
- Persistent bad breath
If you have symptoms of mouth cancer, your GP will carry out a physical examination and ask about your symptoms.
If mouth cancer is suspected, you will be referred to hospital for further tests or to speak to a specialist head and neck surgeon.
It may be necessary to remove a small sample of affected tissue to check for the presence of cancerous cells. This procedure is known as a biopsy.
There are three main methods used to carry out a biopsy in cases of suspected mouth cancer.
A punch biopsy may be used if the suspected affected area of tissue is in an easily accessible place, such as your tongue or the inside of your mouth.
The area is first injected with a local anaesthetic to numb it. The doctor will then cut away a small section of affected tissue and remove it with tweezers.
The procedure is not painful, but can feel a little uncomfortable.
Fine needle aspiration (FNA)
A fine needle aspiration (FNA) is a type of biopsy used if it is suspected a swelling in your neck is the result of mouth cancer.
Your neck is numbed and a needle is used to draw out a small sample of tissue and fluids from the lump. The sample is then checked for cancerous cells.
FNA is not painful but it can be uncomfortable and cause bruising.
A panendoscope is used if the suspected tissue is at the back of your throat or inside one of your nasal cavities.
This is a long thin tube with a camera and a light which is guided through the nose, then used to remove a small section of tissue for the biopsy.
The panendoscope can also check whether cancer has spread from your mouth to further down your throat, such as your larynx (voice box), oesophagus (gullet) or trachea (windpipe).
If the biopsy confirms cancer you will need further tests to check what stage it has reached.
If the cancer is diagnosed late it can have spread from your mouth into the lymphatic system – a series of glands throughout your body which produce many of the specialised cells needed by your immune system.
Once the cancer reaches the lymphatic system, it is capable of spreading to any other part of your body, including your bones, blood and organs.
However, it's uncommon for mouth cancer to spread further than the lymph nodes near your mouth, although in some cases it may also spread to surrounding bones, such as the jaw bone, and in some cases your lungs.
Therefore, the tests will examine your lymph nodes, bones and the tissue near the site of your initial tumour to check for the presence of other tumours.
These tests may include:
- An X-ray
- A magnetic resonance imaging (MRI) scan
- A computerised tomography (CT) scan
- A positron emission tomography (PET) scan
Further biopsies on nearby lymph nodes may also be carried out.
Staging and grading
Once these tests have been completed it should be possible to tell what stage and grade your cancer is:
Staging is a measure of how far the cancer has spread
The grade describes how aggressive the cancer is and how fast it is likely to spread in future
This will help determine whether you have:
Early mouth cancer (usually curable)
Intermediate mouth cancer (may be curable)
Or advanced mouth cancer (not usually curable, but it is usually possible to slow the spread of the cancer and extend lifespan)
There are three grades of mouth cancer: low-grade (the slowest), moderate-grade and high-grade (the most aggressive).
Grading your cancer helps the doctor decide how quickly you need to be treated – read more about treating mouth cancer.
Treatment for oral cancer includes:
- Radiation Therapy
- Targeted Therapy
Treatment of gum cancer begins with seeking regular medical care throughout your life, including regular dental care. Regular medical care allows a health care professional to provide early screening tests that can detect diseases at an early stage when they are most treatable. Regular medical care also provides an opportunity for your health care professional to promptly evaluate symptoms and your risks for developing gum cancer.
The goal of gum cancer treatment is to permanently cure the cancer or to bring about a complete remission of the disease. Remission means that there is no longer any sign of the disease in the body, although it may recur or relapse later.
Common treatments for gum cancer
Common treatments for gum cancer include:
- Chemotherapy to attack cancer cells
- Participation in a clinical trial that is testing promising new therapies and treatments for gum cancer
- Radiation therapy to attack cancer cells
- Surgery to remove the cancer and evaluate how far it has spread
Other treatments for gum cancer
Other therapies may be added to help with your general state of health and any side effects of cancer treatment:
- Antinausea medications if nausea occurs
- Blood cell growth factors to increase the number of white blood cells if levels of these get too low
- Blood transfusions to temporarily replace blood components (such as red blood cells) that have dropped to low levels
- Dietary counseling to help maintain strength and nutritional status
- Occupational and physical therapy to help with eating, swallowing or talking problems
- Pain medications as needed to increase comfort
- Reconstructive surgery to restore structures that have been removed
Some complementary treatments may help some people to better deal with gum cancer and its treatments. These treatments, sometimes referred to as alternative therapies, are used in conjunction with traditional medical treatments. Complementary treatments are not meant to substitute for traditional medical care. Be sure to notify your doctor if you are consuming nutritional supplements or homeopathic (nonprescription) remedies as they may interact with the prescribed medical therapy.
Complementary treatments may include:
- Massage therapy
- Nutritional dietary supplements, herbal remedies, tea beverages, and similar products
