Cancer starts when cells change (mutate) and 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. They can spread to other parts of the body, too. This is called metastasis.
Oral cancer is cancer that starts in cells that make up the inside of the mouth or the lips. Oral cancer is fairly common. It can be cured if found and treated at an early stage (when it's small and has not spread). A healthcare provider or dentist often finds oral cancer in its early stages because the mouth and lips are easy to exam.
The most common type of oral cancer is squamous cell carcinoma. There are other, much less common types.
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. Other factors that increase risk include:
Past or current use of any form of tobacco
Heavy alcohol use
A lot of sun exposure
Human papillomavirus (HPV) infection
Lack of fruits and vegetables in your diet
Chronic mouth irritation, such as from dentures that aren't fitted correctly
Using betel quid or gutka chewing tobacco products
Some inherited conditions, such as Fanconi anemia
Weakened immune system
Talk with your healthcare provider about your risk factors for oral cancer and what you can do about them.
There is no sure way to prevent all mouth 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 correctly
Take care of your mouth and teeth
Oral cancer is often found because a person notices 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
Abnormal bleeding, pain, or numbness in your mouth
A feeling of something caught in your throat
Numbness in your mouth or tongue
Trouble chewing or swallowing
Pain when you chew or swallow
Swelling around your jaw
Loose or painful teeth
A lump, swelling, or mass in your neck that doesn’t go away
Unexpected weight loss
A change in your voice
Pain in your ear or jaw
Many of these may be caused by other health problems. But it's important to see your healthcare provider if you have these symptoms. Only a healthcare provider can tell if you have cancer.
Oral cancer is often found during routine dental exams. Your healthcare provider may check for signs of oral cancer during your regular exams. You should tell your healthcare provider if you have any symptoms.
If your provider thinks you may have oral cancer, you'll need exams and tests to be sure. Your provider will ask you about your health history, your symptoms, risk factors, and family history of disease. An oral exam will be done. This includes looking at your head and neck, and checking inside your mouth. Your provider 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 need more tests. These help your healthcare providers learn more about your overall health and the cancer. They're used to find out the stage of the cancer. The stage is how much cancer there is and how far it has spread (metastasized) in your body. It's one of the most important things to know when deciding how to treat the cancer.
Once your cancer is staged, your provider will talk with you about what the stage means for your treatment. Ask your provider to explain the details of your cancer to you in a way you can understand.
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, 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, how your body will look and work after treatment, 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, immunotherapy, and targeted therapy are systemic treatments. 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.
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 linked with your treatment. There are often ways to manage them. There may be things you can do and medicines you can take to help prevent or control many treatment side effects.
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.
Many people feel worried, depressed, and stressed when dealing with cancer. Getting treatment for cancer can be hard on your mind and body. Keep talking with your healthcare team about any problems or concerns you have. Work together to ease the effect of cancer and its symptoms on your daily life.
