Oral cancer most commonly occurs in middle-aged and older
individuals, although a disturbing number of these malignancies is
also being documented in younger adults in recent years. From an
epidemiological and clinicopathological perspective, "oral cancer"
can be divided into three categories: carcinomas of the oral cavity
proper, carcinomas of the lip vermilion, and carcinomas arising in
the oropharynx. Intraoral and oropharyngeal tumors are more common
among men than women, with a male: female ratio of over 2:1.2.
However, the disparity in the male: female ratio has become less
pronounced over the past half century, probably because women have
been more equally exposing themselves to known oral carcinogens
such as tobacco and alcohol.
