, occur more often in younger people.
Often, cancers of the mouth, nose, and throat are considered together by doctors because of certain similarities. Among the similarities are the type of cancer and the causes. More than 90% of cancers of the mouth, nose, and throat are squamous cell carcinomas, which means the cancer develops in the squamous cells that line the inside of the mouth, nose, or throat. Most people who have mouth, nose, or throat cancers use tobacco, drink alcohol, or both. Another cause of some types of these cancers is viral infection.

Symptoms of Mouth, Nose, and Throat Cancers
Symptoms vary depending on the location of the cancer. Common symptoms of mouth, nose, and throat cancers include
Hoarseness
A lump in the neck
A painful open sore or a growth in the mouth
Difficulty swallowing and resulting weight loss
Sometimes red or white patches (erythroplakia or leukoplakia) in the mouth may be early symptoms.
Diagnosis of Mouth, Nose, and Throat Cancers
Examination by a doctor or dentist
Endoscopy
Biopsy
Some cancers inside the mouth do not cause symptoms at first but can be seen or felt by a doctor or dentist during a routine mouth examination. If a person has symptoms, the doctor can use a flexible viewing tube, called an endoscope, to examine the deeper regions in the mouth, nose, and throat. The diagnosis is made by examining a sample of tissue, called a biopsy, from the suspected cancer. Doctors insert a needle into the growth to get a small amount of tissue or cut out a small piece using a scalpel.
Staging tests
Before they can select the best form of treatment for a person's mouth, nose, or throat cancer, doctors do staging Staging Cancer Cancer is suspected based on a person's symptoms, the results of a physical examination, and sometimes the results of screening tests. Occasionally, x-rays obtained for other reasons, such as... read more tests to determine how advanced the cancer has become, taking into account the cancer's size, invasion into nearby tissues, and distant spread (metastasis).

Prognosis for Mouth, Nose, and Throat Cancers
The outcome of mouth, nose, and throat cancers varies greatly depending on the type, location, cause, and stage of the cancer. In general, outcomes are better when the cancer is diagnosed and treated before it has spread. People with mouth and throat cancers caused by HPV have a better prognosis than a person whose tumors were caused by tobacco or alcohol.
Prevention of Mouth, Nose, and Throat Cancers
It is important for people to eliminate risk factors for mouth, nose, and throat cancers, so everyone should stop using tobacco (smoking and chewing tobacco) and limit how much alcohol they drink. Removing risk factors also helps prevent disease from coming back in people who have been treated for cancer.

Because so many factors are involved in choosing the right treatment, teams of specialists work together to plan a person's care.
Unless a cancer is easily treated, measures to manage a person's pain and quality of life (called palliative treatment) are essential. Pain and palliative care specialists develop plans to manage a person's pain, difficulty eating, choking on secretions, and other troublesome symptoms. Palliative treatment may also include surgery, radiation, or chemotherapy. For example, if a tumor is causing pain but cannot be removed surgically, radiation to the tumor may shrink it, temporarily reducing the person's pain.
