Oral Cancer: Overview
What is oral cancer?
Cancer is made of changed cells that grow out of control. The changed (abnormal) cells
often grow to form a lump or mass called a tumor. Cancer cells can also grow into
(invade) nearby areas. And they can spread to other parts of the body. This is called
Oral cancer is cancer that starts in the mouth or throat. Oral cancer is fairly common
and very curable if found and treated at an early stage. A healthcare provider or
dentist usually finds oral cancer in its early stages because the mouth can be easily
The types of oral cancer are:
Who is at risk for oral cancer?
A risk factor is anything that may increase your chance of having a disease. The exact
cause of someone’s cancer may not be known. But risk factors can make it more likely
for a person to have cancer. Some risk factors may not be in your control. But others
may be things you can change.
Oral cancer is twice as common in men as it is in women. You’re also more at risk
for it if you have:
Used tobacco in the past
Heavily drink alcohol use
A lot of sun exposure
Human papillomaviruses (HPV) infection
Lack of fruits and vegetables in your diet
Chronic mouth irritation, such as from poorly-fitted dentures
Betel nut use
Certain inherited conditions, such as Fanconi anemia
Talk with your healthcare provider about your risk factors for oral cancer and what
you can do about them.
Can oral cancer be prevented?
There is no sure way to prevent all oral and throat cancers. But you can control some
risk factors to help reduce your risk:
Quit using all types of tobacco
Stay away from other people’s tobacco smoke (secondhand smoke)
Limit or don’t drink alcohol
Protect yourself from ultraviolet light exposure
Prevent HPV infection
Eat lots of fruits and vegetables
Have dentures fitted properly
What are the symptoms of oral cancer?
Oral cancer is often found because a person notices unusual changes in their mouth.
The symptoms of oral cancer include:
A sore on your lip or in your mouth that won’t heal
A lump on your lip, in your mouth, or in your throat
A white or red patch on the gums, tongue, or lining of your mouth
Unusual bleeding, pain, or numbness in your mouth
A feeling of something caught in your throat
Trouble chewing or swallowing
Pain when you chew or swallow
A sore throat that doesn’t go away
Swelling around your jaw
Loose or painful teeth
A lump, swelling, or mass in your neck that doesn’t go away
Weight loss that is unexpected
A change in your voice
A pain in your ear
Many of these may be caused by other health problems. But it is important to see your
healthcare provider if you have these symptoms. Only a healthcare provider can tell
if you have cancer.
How is oral cancer diagnosed?
Oral cancer is often found during routine dental or medical exams. Your healthcare
provider may check for signs of oral cancer during your regular exams. And you should
tell your healthcare provider if you have any symptoms.
If your healthcare provider thinks you may have oral cancer, you will need exams and
tests to be sure. Your healthcare provider will ask you about your health history,
your symptoms, risk factors, and family history of disease. He or she will also give
you an oral exam. This involves looking at your head and neck and checking inside
your mouth. He or she may also look at the back of your mouth and throat with small
mirrors or with a thin, flexible, lighted tube. This tube is called a laryngoscope
or a pharyngoscope. Based on the results, your healthcare provider may decide you
need a biopsy to check for cancer.
A biopsy is the only way to confirm cancer. Small pieces of tissue are taken out and
checked for cancer cells. Your results will come back in about 1 week.
After a diagnosis of oral cancer, you’ll likely have other tests. These help your
healthcare providers learn more about your cancer. They can help determine the stage
of the cancer. The stage is how much and how far the cancer has spread (metastasized)
in your body. It is one of the most important things to know when deciding how to
treat the cancer.
Once your cancer is staged, your healthcare provider will talk with you about what
the stage means for your treatment. Ask your healthcare provider to explain the stage
of your cancer to you in a way you can understand.
How is oral cancer treated?
Your treatment choices depend on the type of oral cancer you have, test results, and
the stage of the cancer. The goal of treatment may be to cure you, or control the
cancer, or help ease problems caused by the cancer. Talk with your healthcare team
about your treatment choices, the goals of treatment, and what the risks and side
effects may be. Other things to think about are if the cancer can be removed with
surgery and your overall health.
Types of treatment for cancer are either local or systemic. Local treatments remove,
destroy, or control cancer cells in one area. Surgery and radiation are local treatments.
Surgery is a common treatment for oral cancer. Systemic treatment is used to destroy
or control cancer cells that may have traveled around your body. When taken by pill
or injection, chemotherapy is a systemic treatment. You may have just one treatment
or a combination of treatments.
Oral cancer may be treated with:
Talk with your healthcare providers about your treatment options. Make a list of questions.
Think about the benefits and possible side effects of each option. Talk about your
concerns with your healthcare provider before making a decision.
What are treatment side effects?
Cancer treatment such as chemotherapy and radiation can damage normal cells. This
can cause side effects such as hair loss, mouth sore, and vomiting. Talk with your
healthcare provider about side effects you might have and ways to manage them. There
may be things you can do and medicines you can take to help prevent or control side
After surgery for oral cancer, you may need extra care to adjust to new ways of eating,
drinking, speaking, and breathing. The types of changes you have depend on the type
of surgery that was done.
Coping with oral cancer
Many people feel worried, depressed, and stressed when dealing with cancer. Getting
