Oral Cancer

There are two distinct pathways by which most people come to oral cancer. One is through the use of tobacco and alcohol, a long term historic problem and cause, and the other is through exposure to the HPV-16 virus (human papilloma virus version 16), a newly identified etiology, and the same one which is responsible for the vast majority of cervical cancer in women. A small percentage of people (under 7%)  do get oral cancers from no currently identified cause. It is currently believed that these are likely related to some genetic predisposition.

While some think this is a rare cancer, mouth cancers will be newly diagnosed in about 115 new individuals each day in the US alone, and a person dies from oral cancer every hour of every day. If you add the sub category of laryngeal throat cancers, the rates of occurrence (about 12,000 additional new cases per year) and death are significantly higher. When found at early stages of development, oral cancers have an 80 to 90% survival rate. Unfortunately at this time, the majority are found as late stage cancers, and this accounts for the very high death rate of about 43% at five years from diagnosis (for all stages and etiologies combined at the time of diagnosis), and high treatment related morbidity in survivors. Late stage diagnosis is not occurring because most of these cancers are hard to discover, Though some like HPV origin disease have unique discovery issues), it is because of a lack of public awareness coupled with the lack of a national program for opportunistic screenings which would yield early discovery by medical and dental professionals. worldwide the problem is far greater, with new cases annually exceeding 450,000.
