Each year in the
US, approximately 30,000 people are diagnosed with
oral cancer. Worldwide the problem is far greater,
with new cases annually approaching 300,000. Mouth
cancer, tongue cancer, and throat cancer fall under
the category of Oral cancer. In the US alone, a
person dies from oral cancer every hour of every
day. When found early, oral cancers have an 80 to
90 % cure rate. Unfortunately, the majority are
found at late stage cancers, accounting for the
very high death rate. .Of those 30,000 newly diagnosed
individuals, only half will be alive in 5 years.
The death rate for oral cancer is higher than that
of cervical cancer, Hodgkins disease, cancer of
the brain, liver, testes, kidney, or skin cancer
(malignant melanoma).
Often it is only
discovered when the cancer has metastasized (spread)
to another location, most likely the lymph nodes
of the neck. Once the cancer has spread, the prognosis
is significantly worse than when it is caught in
a localized area. At these later stages, the primary
tumor has had time to invade deep into local structures.
Oral cancer is particularly dangerous because it
has a high risk of producing second, primary tumors.
This means that patients who survive a first encounter
with the disease, have up to a 20 times higher risk
of developing a second cancer.
90% of Oral cancer
are squamous cell carcinomas( the type of cancer)
occurring more commonly in men and those over the
age of 40. It is a cancer which occurs twice as
often in the black population as in whites.
