After
cardiovascular disorders, cancer is the second leading cause of death in the
world. It affects both genders, and its economic impact is greater than any
other cause of death in the world. The total economic impact of premature death
and disability from cancer worldwide was $895 billion in 2008. This data
represents 1.5% of the world’s gross domestic product.
Among the risk factors
for cancer, age is one of the most important; cancer incidence and
cancer-related mortality rises exponentially after 50 years of age. Due
to increases in birth rate and life expectancy, the number of older individuals
is currently increasing around the world. With this trend, the prevalence of
cancer is likely to rise. This fact has important implications for the
implementation of preventive strategies and treatment for cancer in older age
groups. In older individuals, some cancers may be more aggressive or more
indolent than in younger adult age groups. Read more..............
A
lead series of cohorts has been run by the American Cancer Society (ACS) which
has led U.S. prospective studies documenting the link between smoking
cigarettes and lung cancer from the first study of over 188,000 men, to the
Cancer Prevention Study 1, follow-up of 1 million men and women and also documenting
the benefits of stopping smoking where after more than one year the risk waslower than current smokers and took more than 10 years to return to the risk of
never smokers. Subsequent follow-up data informed the estimates of tobacco
smoking to cancer mortality in the USA providing essential input to the report
by Doll and Peto on the potential to prevent cancer.
Further updates of the ACS
cohorts refined our understanding of the burden of tobacco across decades . The
Cancer Prevention Study cohorts have also contributed leadership to documenting
the burden due to overweight and obesity setting the stage for the
International Agency for Research on Cancer report on this topic and global estimates . Like other cohorts studying
lifestyle and diet data , the ACS also contributed major data on mortality due
to alcohol. Read more...............
