How are head and neck cancers diagnosed?

Dr. De Vizio of Colgate answered:A doctor diagnoses head and neck cancer by examining the patient, checking for symptoms, reviewing medical history, and conducting a series of diagnostic tests, including x-rays and laboratory analysis of skin and blood samples. Head and neck cancer usually begins in cells located where mucous naturally occurs, such as the mouth, nose, and throat.
Tests may vary depending on symptoms, such as a lump, sore, or pain in the throat that doesn’t go away; blocked sinuses that don’t clear; or a white or red patch on the tongue, gums, inside cheek, or elsewhere in the mouth.

Dr. Patrick Maguire answered:Most patients will be seen initially by a primary care physician and referred to an ear, nose and throat (ENT) specialist for diagnosis of head and neck cancer. This type of surgeon will generally perform a panendoscopy with the patient under sedation. This procedure involves placing a thin fiberoptic scope into the throat, in order to see the entire throat lining, including the larynx (voicebox). Biopsy may be performed during panendoscopy to confirm the presence or absence of cancer, as well as the type. For patients who have enlarged lymph nodes, biopsy may be performed under computerized tomography (CT) guidance.Most patients will be seen initially by a primary care physician and referred to an ear, nose and throat (ENT) specialist for diagnosis of head and neck cancer.

Riverside Cancer Care Center answered:To find the cause of symptoms, a doctor evaluates a person's medical history, performs a physical examination, and orders diagnostic tests. The exams and tests conducted may vary depending on the symptoms. Examination of a sample of tissue under the microscope is always necessary to confirm a diagnosis of cancer. Some exams and tests that may be useful are described below:
Physical examination may include visual inspection of the oral and nasal cavities, neck, throat, and tongue using a small mirror and/or lights. The doctor may also feel for lumps on the neck, lips, gums, and cheeks. Endoscopy is the use of a thin, lighted tube called an endoscope to examine areas inside the body. The type of endoscope the doctor uses depends on the area being examined. For example, a laryngoscope is inserted through the mouth to view the larynx; an esophagoscope is inserted through the mouth to examine the esophagus; and a nasopharyngoscope is inserted through the nose so the doctor can see the nasal cavity and nasopharynx. Laboratory tests examine samples of blood, urine, or other substances from the body. X-rays create images of areas inside the head and neck on film. CT (or CAT) scan is a series of detailed pictures of areas inside the head and neck created by a computer linked to an x-ray machine. Magnetic resonance imaging (or MRI) uses a powerful magnet linked to a computer to create detailed pictures of areas inside the head and neck. PET scan uses sugar that is modified in a specific way so it is absorbed by cancer cells and appears as dark areas on the scan. Biopsy is the removal of tissue. A pathologist studies the tissue under a microscope to make a diagnosis. A biopsy is the only sure way to tell whether a person has cancer. If the diagnosis is cancer, the doctor will want to learn the stage of disease. Staging is a careful attempt to find out whether the cancer has spread and, if so, to which parts of the body. Staging may involve an examination under anesthesia (in the operating room), x-rays and other imaging procedures, and laboratory tests. Knowing the stage of the disease helps the doctor plan treatment.
