Skin Cancer – Facts and Statistics
The number of skin cancer cases has increased in the United
States. More than 1 million
cases of basal cell or squamous
cell cancer will be diagnosed annually. The most serious form
of skin cancer, malignant m
elanoma, is expected to be diagnosed in 55,100 persons in
2004.1 Since 1981, the
incidence of melanoma has increased a
little less than 3 percent per year. Melanoma is the most
common cancer among people 25 to 29 years old.
The three major types of skin cancer are basal cell carcinoma,
squamous cell carcinoma, and melanoma.
Basal cell and squamous cell carcinomas
can cause substantial illness and, if untreated, can cause
considerable damage and disfigurement. If detected and treated
early, however, these carcinomas have a cure rate of more
than 90%
Malignant melanoma causes more than 75% of all deaths from
skin cancer. This disease can spread to other organs, most
commonly the lungs and liver. Malignant melanoma diagnosed
at an early stage usually can be cured, but melanoma diagnosed
at a late stage is more likely to spread and cause death.
Exposure to the sun's ultraviolet (UV) rays appears to be
the most important environmental factor in developing skin
cancer. This makes skin cancer a largely preventable disease
when sun protective practices and behaviors are consistently
applied and utilized. UV radiation is also a factor in the
development of lip cancer, making sun protection even more
important. UV rays from artificial sources of light, such
as tanning beds and sun lamps are just as dangerous as those
from the sun, and should also be avoided. Unfortunately, despite
the fact that both tanning and burning can increase one's
risk of skin cancer, most Americans do not protect themselves
from UV rays.
