Oral cancer belongs to a larger group of cancers called head and neck cancers.
It is a cancer that develops in the tissues of the mouth or throat — in the mouth, oral cancer can be found on the lip, nasal cavity, floor of the mouth, roof of the mouth, cheek lining, gingiva, palate or on the tongue; in the throat area, it is found at the back of the mouth (known as the oropharynx).
Globally, oral cancer is listed as the sixth most common type of cancer, with India being the second country having the highest number of oral cancer cases. In India, around 77,000 new cases and 52,000 deaths are reported annually due to mouth cancer. (Source: NCBI – Data as of September 2020).
As the cancer progresses, it can involve the bones of the upper or lower jaw, it can spread to lymph nodes in the neck, or can spread elsewhere in the body. Most oral cancers come from the lining on the inside of the mouth.
