This video will give you more information about this type of cancer and how it affects the body. Head and neck cancer can develop in certain areas, such as: the sinuses, which are hollow spaces in the bones of the head around the nose; the nasal cavity; the mouth, also known as the oral cavity; the throat, also known as the pharynx; the voice box, also known as the larynx; and the salivary glands, which are organs that help you digest food. The cells that line most of these structures are called squamous cells. The most common type of head and neck cancer, called squamous cell carcinoma, begins in these cells; Here, normal cells transform into abnormal cells called cancer cells. Over time, these cells can grow out of control and clump together, forming a tumor. These tumors can grow and spread, destroying healthy tissue. Symptoms of head and neck cancer vary depending on the location of the cancer. In general, symptoms may include: a sore that doesn't heal, a lump that doesn't go away, a sore throat that doesn't go away, pain or difficulty swallowing, ear pain, a hoarse voice or change in voice, and difficulty breathing. Other health problems can cause these symptoms. It's important to see your doctor to be sure. If you have head and neck cancer, your doctor will try to find out the extent of the disease and if it has spread. This is called staging. Cancer stages range from 0 to 4. A lower stage means less cancer growth; a higher stage means more cancer growth. The two main risk factors for head and neck cancer are alcohol and tobacco use, including smokeless tobacco. Other risk factors include infection with certain viruses, such as human papillomavirus or Epstein-Barr virus, exposure to certain substances in the workplace, and prior radiation therapy to the head and neck. If you have been diagnosed with head and neck cancer, continue to talk with your doctor and cancer care team. ANH18213
