Throat cancer is a type of head and neck cancer. Throat cancer has different names, depending on which part of the throat is affected. The different parts of your throat are called the oropharynx, the hypopharynx, the nasopharynx, and the larynx, or voice box.

The main risk factors for throat cancer are using tobacco heavy drinking. Certain types of throat cancer also have other risk factors. For example, having HPV is a risk factor for oropharyngeal cancer.

Symptoms of throat cancer may include:

• A sore throat that does not go away
• A lump in the neck
• Pain or ringing in the ears
• Trouble swallowing
• Ear pain

To diagnose throat cancers, doctors may do a physical exam and history, imaging tests, and a biopsy. You may also need other tests, depending on the type of cancer. Treatments include surgery, radiation therapy, and chemotherapy. Treatment for some types of throat cancer may also include targeted therapy. Targeted therapy uses drugs or other substances that attack specific cancer cells with less harm to normal cells.

Oral cancer is cancer of the mouth. It is a type of head and neck cancer. Most oral cancers are squamous cell cancers. They begin in the flat cells that cover the surfaces of your mouth, tongue, and lips. The cancer cells may spread into deeper tissue as the cancer grows.

Most oral cancers are related to tobacco use, heavy alcohol use, or an HPV infection.

Anyone can get oral cancer, but you are more likely to develop it if you:

• Use tobacco or drink lots of alcohol. Your risk of developing oral cancer is even higher if you do both.
• Are male.
• Are over ago 40.
• Have HPV.
• Have a history of head or neck cancer.
• Get frequent sun exposure (for lip cancer).

The symptoms of oral cancer may include:

• A white or red patch in your mouth
• A lip or mouth sore that won't heal
• Bleeding, pain, or numbness in the lip or mouth
• Loose teeth or dentures that no longer fit well
• Problems or pain with swallowing
• A lump in your neck
• Ear pain
• Trouble moving your mouth or jaw
• Swelling of the jaw
• A sore throat or feeling that something is caught in the throat

If you have any of these symptoms for more than two weeks, see your health care provider or dentist. Oral cancer can spread quickly, so it's important to find it early.

To find out if you have oral cancer, your provider may use:

• A physical exam of the lips and mouth.
• An endoscopy.
• A biopsy or other procedure to collect cells from the lip or oral cavity. The cells are viewed under a microscope to find out if they are abnormal.
• Imaging tests.

The treatments for oral cancer include surgery, radiation therapy, or both. After surgery, some people also need chemotherapy to kill any cancer cells that are left.

There are steps you can take to help prevent oral cancer:

• Not smoking
• Limiting alcohol use or not drinking at all
• Getting regular dental exams
