Oral cancer: It is the type of cancer which affects the lips, tongue, gums, inside of the cheeks and mouth. The common symptoms of oral cancer include red/white patches inside the mouth, swelling in the jaw, bleeding, and pain in the mouth.

Throat cancer: Also known as the cancer of the pharynx, this type of cancer affects the pharynx, a tube that originates from the nose and connects to the esophagus (food pipe). It includes the tonsils, back of the tongue and soft palate in the mouth. Throat cancer may show symptoms such as pain during swallowing, neck or throat pain, earache, difficulty in hearing and troubled breathing.

Larynx cancer: As the name suggests, it is the cancer of the larynx, also known as the voice box. It is the structure that holds the vocal cords and epiglottis (a structure that hangs at the back of the throat). Some of the common signs and symptoms of larynx cancer are ear pain, voice changes, and pain when swallowing.

Nasal cavity cancer: It is the type of head and neck cancer in which the nasal cavity, space inside the nose, is affected. It also affects the paranasal sinuses, which are the spaces present inside the bones around the nose. The symptoms to watch out for include headaches, nosebleeds, toothache, blocked sinuses, chronic sinus infections, and swelling around the eyes.

Salivary gland cancer: Salivary glands, glands which produce saliva, are present in the floor of the mouth and near the jawbone. The symptoms that indicate cancer of the salivary glands include swelling under the chin or jawline, pain in the face and chin that fails to subside and numbness of the facial muscles.

After obtaining a diagnosis, doctors assign a disease stage (cancers are staged I to IV) to cancer basis outcome of investigations. The treatment options are discussed among the surgical, radiation and medical oncologists, pathologists and radiologists. Usually, head and neck cancer treatments are classified as early-stage cancer and advanced stage cancer treatment.

Early stage cancer (I and II) is generally treated with single modality treatment which is surgery or radiation therapy. However, this depends upon the clinical presentation and your doctor makes an informed decision based on various parameters. The choice of treatment is dictated by the site and type of cancer, and also the number of risk factors a patient has.
