Larynx cancer is a Head and Neck Cancer

 

What is cancer?

Cancer is a group of many related diseases that begin in cells, the body's basic unit of life. Normally, cells grow and divide to form new cells in an orderly way. They perform their functions for a while, and then they die. Sometimes, however, cells do not die. Instead, they continue to divide and create new cells that the body does not need. The extra cells form a mass of tissue, called a growth or tumor. There are two types of tumors: benign and malignant. Benign tumors are not cancer. They do not invade nearby tissue or spread to other parts of the body. Malignant tumors are cancer. Their growth invades normal structures near the tumor and spreads to other parts of the body. Metastasis is the spread of cancer beyond one location in the body.

What kinds of cancers are considered cancers of the head and neck?

Most head and neck cancers begin in the cells that line the mucosal surfaces in the head and neck area, e.g., mouth, nose, and throat. Mucosal surfaces are moist tissues lining hollow organs and cavities of the body open to the environment. Normal mucosal cells look like scales (squamous) under the microscope, so head and neck cancers are often referred to as squamous cell carcinomas. Some head and neck cancers begin in other types of cells. For example, cancers that begin in glandular cells are called adenocarcinomas.

Cancers of the head and neck are further identified by the area in which they begin:

Oral cavity. The oral cavity includes the lips, the front two-thirds of the tongue, the gingiva (gums), the buccal mucosa (lining inside the cheeks and lips), the floor (bottom) of the mouth under the tongue, the hard palate (bony top of the mouth), and the small area behind the wisdom teeth.

Salivary glands. The salivary glands produce saliva, the fluid that keeps mucosal surfaces in the mouth and throat moist. There are many salivary glands; the major ones are in the floor of the mouth, and near the jawbone.

Paranasal sinuses and nasal cavity. The paranasal sinuses are small hollow spaces in the bones of the head surrounding the nose. The nasal cavity is the hollow space inside the nose.

Pharynx. The pharynx is a hollow tube about 5 inches long that starts behind the nose and leads to the esophagus (the tube that goes to the stomach) and the trachea (the tube that goes to the lungs). The pharynx has three parts:

 Nasopharynx. The nasopharynx, the upper part of the pharynx, is behind the nose.

 Oropharynx. The oropharynx is the middle part of the pharynx. The oropharynx includes the  soft palate (the back of the mouth), the base of the tongue, and the tonsils.

 Hypopharynx. The hypopharynx is the lower part of the pharynx.

Larynx. The larynx, also called the voicebox, is a short passageway formed by cartilage just below the pharynx in the neck. The larynx contains the vocal cords. It also has a small piece of tissue, called the epiglottis, which moves to cover the larynx to prevent food from entering the air passages.

Lymph nodes in the upper part of the neck. Sometimes, squamous cancer cells are found in the lymph nodes of the upper neck when there is no evidence of cancer in other parts of the head and neck. When this happens, the cancer is called metastatic squamous neck cancer with unknown (occult) primary.

Cancers of the brain, eye, and thyroid as well as those of the scalp, skin, muscles, and bones of the head and neck are not usually grouped with cancers of the head and neck.
