Cancer Burden
The American Cancer Society (ACS) estimates that, in 2003, more
than 556,500 Americans will die of cancermore than 1,500 people
every dayand that about 1,334,100 new cases of cancer will
be diagnosed.1 These estimates
do not include carcinoma in situ (except urinary bladder) or basal
and squamous cell skin cancers. Cancer is the second leading cause
of death in the United States, accounting for one of four deaths.
From 1950 to 1991, cancer death rates increased steadily. Rates
began to decline in 1991, largely because of a decline in rates
of lung cancer deaths.2
However, the aging and increasing size of the U.S. population will
cause the total number of cancer cases to double by 2050 if current
incidence rates remain steady.3
The National Cancer Institute (NCI) of the National Institutes
of Health (NIH) estimates that almost nine million Americans with
a history of cancer were living in 1997; some were under treatment
and some were considered cured.4 The combined 5-year survival rate
for Americans with any type of cancer is 62%.1
The ACS estimates that cancers that can be detected by screening
account for about half of all new cancer cases. If all these cancers
were detected at a localized stage through appropriate screening,
the 5-year survival rate would approach 95%.1
For these reasons, the bulk of cancer prevention and control research
dollars are dedicated to the prevention and early detection of these
cancers.

African Americans have higher rates of many cancers than other
racial or ethnic groups. During 19921999, the overall cancer
incidence rate per 100,000 persons was 526.6 among African Americans,
480.4 among whites, 329.6 among Hispanics, 348.6 among Asian/Pacific
Islanders, and 244.6 among American Indians/Alaska Natives. Racial
disparities in outcomes are often even more pronounced than disparities
in incidence rates. For example, although breast cancer is diagnosed
more often in white women, African American women are more likely
to die of the disease. The overall cancer mortality rate is also
about one-third higher among African Americans than among whites.1
Mortality rates also vary by gender. The most recent age-adjusted
annual cancer death rates were 259.1 for U.S. men and 171.4 for
U.S. women.3
Cancers financial costs are significant. NCI estimates that
cancers cost the nation more than $171.6 billion in 2002: $60.9
billion in direct medical costs (i.e., expenditures for medical
procedures and services associated with treatment and care for cancer),
$15.5 billion in indirect morbidity costs (such as the value of
work disability and absenteeism associated with cancer), and $95.2
billion for indirect mortality costs (such as the cost of lost productivity
due to premature death). More than half of all medical costs for
cancer are estimated to be for the treatment of breast, lung, prostate,
and colorectal cancers,4
again underscoring the importance of directing prevention and early
detection activities toward these cancers.
The nonmonetary costs of cancer are also substantial but cannot
be adequately quantified. Cancer pain, though usually manageable,
can be a significant problem, as can the discomfort of treatment
and damage to the cancer patients self-image. After treatment
for cancer, many people can continue an active, vital lifebut
they must live with the fear and uncertainty that the cancer might
return. As one cancer survivor commented, the fear for me
now, eight and a half years out from my diagnosis, is generally
background noise. Most of the time I am not aware of it, yet it
waits ready to pounce at the slightest provocation. 5
Because between eight and nine million Americans have a history
of cancer, the toll of the disease is enormous no matter how the
burden is calculated.
