From here.
As of 2009, the overall death rate for
cancer in the United States had declined 20 percent from its peak in
1991, translating to the avoidance of approximately 1.2 million
deaths from cancer, 152,900 of these in 2009 alone.
The latest report finds that cancer
death rates decreased from their peak of 215.1 per 100,000 in 1991 to
173.1 per 100,000 in 2009. Death rates continue to decline for all
four major cancer sites: lung, colon and rectum (colorectum), breast,
and prostate. Over the past two decades, death rates have decreased
from their peak by more than 30% for cancers of the colorectum,
female breast, and male lung, and by more than 40% for prostate
cancer. These large drops are primarily due to reductions in smoking
for lung cancer and to improvements in early detection and treatment
for colorectal, breast, and prostate cancers.
The authors say as encouraging as those
drops are, further progress can be accelerated by applying existing
cancer control knowledge across all segments of the population, with
an emphasis on those groups in the lowest socioeconomic bracket and
other underserved populations.
According to the study, a total of
1,660,290 new cancer cases and 580,350 cancer deaths are projected to
occur in the United States in 2013. Among men, cancers of the
prostate, lung and bronchus, and colorectum will account for half of
all newly diagnosed cancers; prostate cancer alone will account for
28% (238,590) of incident cases in men. Among women, the three most
commonly diagnosed types of cancer in 2013 will be breast, lung and
bronchus, and colorectum, accounting for about half of all cases.
Breast cancer alone is expected to account for 29% (232,340) of all
new cancer cases among women.
While incidence rates are declining for
most cancer sites, they are increasing among both men and women for
melanoma of the skin and cancers of the liver, thyroid, and pancreas.
Overall cancer incidence rates decreased slightly in males (by 0.6%
per year) and were stable in females in the most recent five year
period for which there is data (2005-2009).
Cancers of the lung and bronchus,
prostate, and colorectum in men and cancers of the lung and bronchus,
breast, and colorectum in women continue to be the most common causes
of cancer death. These four cancers account for almost half of the
total cancer deaths among men and women. In 2013, lung cancer is
expected to account for 26% of all female cancer deaths and 28% of
all male cancer deaths.
Cancer death rates decreased by 1.8%
per year in males and by 1.5% per year in females during the most
recent five years of data (2005-2009). These declines have been
consistent since 2001 and 2002 in men and women, respectively, and
are larger in magnitude than those occurring in the previous decade.
Between 1990/1991 and 2009, cancer death rates decreased by 24% in
men, 16% in women, and 20% overall.
