The ailment occurs when cells in a person’s throat develop genetic mutations. These mutations cause cells to grow wildly and continue living after healthy cells would normally die. The accumulating cells can form a tumor in a person’s throat.
It is a relatively rare type of cancer, and according to the National Cancer Institute, the lifetime risk of developing cancer in the mouth or throat is around 1.2%.
Throat cancer has also been linked to other types of cancers. In fact, some people diagnosed with throat cancer are diagnosed with esophageal, lung, or bladder cancer at the same time.
Throat cancer is often grouped into two categories: pharyngeal cancer and laryngeal cancer.
Pharyngeal cancer develops in the pharynx, which is the hollow tube that runs from behind the nose to the top of the windpipe.
Laryngeal cancer, on the other hand, forms in the larynx, which is the voice box.
The two primary types of throat cancer are (i.) Squamous cell carcinoma, which affects the flat cells lining the throat, and (ii.) Adenocarcinoma, which affects the glandular cells.
