USA cancer death rates are dropping

Share

A study published Thursday by the American Cancer Society indicates rates dropped again between 2014 and 2015. That amounts to 4,700 new diagnoses each day.

That gap is narrowing, but, according to the report, the improvements apply mostly to older Americans, 'likely in part due to universal health care access for seniors through Medicare, ' the American Cancer Society said in its press release.

Women have a 37.6 percent percent chance of ever being diagnosed with cancer.

Researchers agree, however, that the reasons behind racial disparities in cancer deaths are multi-pronged and still not fully understood.

'Strikingly though, tobacco remains by far the leading cause of cancer deaths today, responsible for almost three in ten cancer deaths, ' he added.

Between 1991 and 2015, cancer deaths fell by 26 percent.


For women, breast cancer remains the most commonly diagnosed form, accounting for 30 percent of all new cancer cases.

Among men, prostate, lung, and colorectal cancers account for 42 percent of cases.

"The decline in cancer mortality over the past two decades is primarily the result of steady reductions in smoking and advances in early detection and treatment", the report reads. They are based on models that include trends through the most recent data year and can not anticipate abrupt fluctuations for changes in detection practices, like PSA testing and prostate cancer. A fall of 52 percent is noticed in relation to prostate cancer from 1993 to 2015. Mortality rates remain 31 percent higher in blacks than in whites under 65.

With the variation in cancer death rate, the lifetime probability is still higher in men than women. Men have a 39.7 percent chance.

Though the racial gap in cancer deaths continues to narrow as well, this mainly reflects progress for older age groups, which masks "stark persistent inequalities for young and middle-aged black Americans", the report says.

In 13 states, the death rates were not statistically significantly different between whites and blacks.
