This year, the U.S. will see nearly 1.7 million new cancer cases and
nearly 600,000 cancer deaths, according to American Cancer Society
projections published in CA: A Cancer Journal for Clinicians.
The report's authors point out that cancer continues to be a leading
cause of death in the U.S., however, and new diagnoses for some
cancers are increasing.
"It’s kind of a good news, bad news story," said ACS's Rebecca
Siegel, who is based in Atlanta.
Cancer deaths fell by 23 percent in the decade before 2012, the
latest period for which data are available. The decrease represents
about 1.7 million fewer deaths since rates peaked in 1991, says the
report.
The decrease is largely due to fewer deaths from breast, colon,
rectal and prostate cancers. Also, there are fewer lung cancer
deaths as a result of fewer people smoking.
Breast cancer remains the leading cause of cancer death for women
ages 20 to 59, and leukemia is the leading cause of cancer death
among men ages 20 to 39. Lung cancer is the leading cause of cancer
death for older men and women.
The number of new cancer diagnoses appears mostly stable in women.
Among men, the rate of new cases fell 3 percent per year between
2009 and 2012, with the drop largely due to a reduction in prostate
cancer screening.
Rates of some cancers are increasing, including those often
associated with obesity.
For example, incidence and mortality rates for endometrial cancer
are up, said Siegel, "likely due to the obesity epidemic."

The report says endometrial cancer risk climbs 5 percent with every
five-point gain in body mass index, which is a measure of weight in
relation to height.
Another area of concern are gaps between races, Siegel told Reuters
Health.
For example, black men have the highest rates of new cancer
diagnoses and deaths. In fact, black men have higher diagnosis and
death rates than non-Hispanic white men for every malignancy except
kidney cancer.
"The improvements in cancer prevention and early detection and
treatment aren’t disseminated equally among the population," said
Siegel.
"Extending these improvements to underserved populations would
accelerate a decline in death rates," she said.
The report too says existing tools to fight cancer need to be
applied to all segments of the population. Also, advancing the fight
will require more research and funding.
"A lot of progress has been made, but there is more work to do,"
said Siegel.
