The United StatesEarlier this year, the American Cancer Society (ACS) released its document Cancer Facts & Figures 2008, and here are some findings from the document: • Cancer mortality rates
in the USA continue to decline, but the number of
actual cancer-related deaths has gone up. That is,
death rates have decreased by 18.4% among men and
10.5% among women since the early 1990s, but by 2005
(the last year stats were available), there were
559,312 cancer deaths, compared to 553,888 in 2004.
The explanation, according to a press
release: "ACS epidemiologists attribute the
rise in part to normal population changes. In 2005,
the decrease in death rate was simply not large enough
to offset the influence of aging in the population
… In addition, there was a smaller decline
in the death rate than in previous years. The cancer
death rate dropped 1% between 2004 and 2005, compared
with 2% between both 2002 to 2003 and 2003 to 2004."
• The ACS estimates that
there will be 437,180 new cancer cases (745,180 in
men and 692,000 in women) and 565,650 cancer deaths
(294,120 among men and 271,530 among women) in 2008.
(The estimate does not include basal and squamous
cell skin cancers and non-invasive carcinomas except
urinary bladder.)
• Leading sites for new
cancer cases in males: prostate, at 186,320, representing
25% of new cases. And the leading cause of death
in males: lung and bronchus cancer, at 90,810, representing
31% of cancer deaths.
• Leading sites for new
cancer cases in females: breast, at 182,460, representing
26% of new cases. And the leading cause of death
in females: lung and bronchus cancer, at 71,030,
representing 26% of cancer deaths.
• African American men
have a 19% higher incidence rate and 37% higher death
rate from all cancers combined compared to white
men. Compared to white women, African American women
are less likely to get cancer, but more likely to
die from it.
• An estimated 10,730 new
cases of cancer among children aged 0 to 14 years
are estimated for 2008. An estimated 1,490 deaths
are expected to occur. The most common childhood
cancer is leukemia, representing 32.6% of cases.
• The National
Cancer Institute estimates that approximately
10.8 million Americans with a history of cancer were
alive in January 2004. Some were cancer-free, and
others were undergoing treatment.
• The five-year relative
survival rate for all cancers diagnosed between 1996
and 2003 is 66%, up from 50% between 1975 and 1997.
• The National
Institutes of Health estimate overall costs
of cancer in 2007 at $219.2 billion, with $89.0 billion
for direct medical costs; $18.2 billion for indirect
morbidity costs (i.e., cost of lost productivity
due to illness); and $112.0 billion for indirect
mortality costs (i.e., cost of lost productivity
due to premature death). * * * * * CanadaThe Canadian Cancer Society (CSC) has the following highlights in its document Canadian Cancer Statistics 2007: • The CSC estimated 159,900
new cancer cases and 72,700 deaths for 2007, with
men outnumbering women for new cases by 7% and for
deaths by 12%.
• Lung cancer is the leading
cause of cancer deaths in both males (29%) and females
(26%).
• Three types of cancer
account for at least 55% of new cases in each sex.
In males, these are prostate, lung, and colorectal,
and in females, these are breast, lung, and colorectal.
• Incidence and mortality
rates are higher in Atlantic Canada and Quebec, and
lowest in British Columbia. Incidence and mortality
rates in Ontario are lower than the national average.
• Since 1994, mortality
rates have declined for all cancers combined, and
for most types of cancer in both sexes, with exceptions
being lung cancer in females and liver cancer in
males.
• 44% of new cancers and
60% of deaths due to cancer occur in those aged at
least 70 years, while 20% of new cancers and 18%
of cancer deaths will occur in young and middle-aged
adults in their most productive stage of life.
• Based on current mortality
rates, 24% of females and 28% of males will die from
cancer.
• Each year, about 1,300
children will develop cancer, and about 210 will
die. Leukemia was the most common cancer, accounting
for 25% of new cases.
