One in
three people will contract cancer, and one in
four will die from the disease.
Within
five years, cancer will surpass heart disease
as the leading cause of death, according to the
American Hospital Association.
In 1994,
1.2 million new cancer cases were added to the
more than eight million people in the U.S. who
have already been diagnosed with cancer.
Since
1950, the overall cancer incidence has increased
by 44 percent; the incidence of breast cancer
and male colon cancer by about 60 percent; testis,
prostate and kidney by 100 percent; and other
cancers, such as malignant melanoma, multiple
myeloma and some lymphomas, by over 100 percent.
The estimated
annual cost of cancer to the United States, excluding
incalculable psychosocial costs, is $110 billion,
approximately 2 percent of the GNP.
An estimated
80 million people have health insurance insufficient
to cover the costs of a catastrophic illness such
as cancer.
Annual
production rates for synthetic, carcinogenic and
other industrial chemicals exploded from 1 billion
pounds in 1940 to more than 500 billion pounds
annually during the 1980s.
Recent
National Cancer Institute studies have linked:
non-Hodgkin's lymphoma and exposure to solvents,
oils, and greases; elevated risks for multiple
myelorna among men and women employed in the textile
and plastic industries; lymphoma among laboratory
workers at the U.S. Department of Agriculture;
and lung cancer among workers who developed silicosis.
The rates
of certain types of cancer among some industrial
workers are up to 10 times higher than in the
general population. Children of workers handling
chemical carcinogens have sharply increase cancer
rates. For example, the risks of childhood leukemia
are increased two-to-five-fold if, during their
mother's pregnancies, their fathers worked with
spray paints, dyes or pigments.
Some 75
percent of all cancers develop in those over 55,
but notable exceptions include childhood leukemia,
testicular and brain cancers - which mainly strike
young people and have been increasing at an alarming
rate, particularly among peak age groups For example,
there has been an approximate 300 percent increase
in testicular cancer among those aged 25-34 since
the 1950s.
During
the 1990s, nearly 2 million women will have been
diagnosed with breast cancer and 460,000 will
have died. Between 1950 and 1989, the incidence
of breast cancer increased by 53 percent.
There
has been an approximate doubling in. lung cancer
rates in recent decades among non- smokers. A
wide range of occupational exposures and urban
air pollution have been shown to cause lung cancer.
"Occupational
studies have played a major role in identifying
well-established environmental carcinogens, such
as asbestos, benzene, arsenic, aromatic amines,
coal tars, vinyl chloride, chromium, and wood
dust." Measures of Progress Against Cancer - Cancer
Prevention, Significant Accomplishments 1982-1992,
The National Cancer Institute.
"It is
well established that primary prevention is the
most effective means of disease control. This
is particularly true of cancer." Measures of Progress
Against Cancer - Cancer Prevention.
"Lack
of appreciation of the potential hazards of environmental
and food source contaminants, and laws, policies,
and regulations protecting and promoting tobacco
use worsen the cancer problem and drive up health
care costs." Cancer At a Crossroads: A Report
to Congress for the Nation, National Cancer Advisory
Board, September 1994.
"While
individuals have a responsibility to change high-risk
behavior, government and society have responsibilities
to identify and prevent workplace and environmental
hazards, restrict advertising of unsafe products,
require accurate product labeling, and provide
culturally targeted education about cancer risk
and prevention." Cancer At a Crossroads
"The elimination
or reduction of exposure to carcinogenic agents
is a priority in the prevention of cancer. We
are just beginning to understand the full range
of health effects resulting from the exposure
to occupational and environmental agents and factors."
Cancer at a Crossroads
"We spend
close to $100 billion a year on cancer treatment
in this country. If we are going to get on top
of this problem, we absolutely have to focus more
on prevention." Dr Devra Lee Davis, senior adviser
to the assistant secretary for health and human
services
