Deaths by cancer on a steady 25-year decline in the United States, new report finds

But the trend is not reflected in all populations, American Cancer Society notes

The death rate from cancer in the United States has seen a steady decline in the past 25 years, according to annual statistics from the American Cancer Society (ACS). 

Between 1991 — the peak year for cancer deaths — and 2016, the cancer death rate for men and women combined had fallen 27 percent, according to a study by the American Cancer Society, published Tuesday in CA: A Cancer Journal for Clinicians. This downswing converts to an estimated 1.5 percent per year and more than 2.6 million deaths avoided over the 25-year study period, according to the ACS. 

The American Cancer Society credits the drop in cancer mortality to steady reductions in smoking and advances in early detection and treatment. But the organization notes the trend is not reflected in all populations — the racial gap in cancer deaths is slowly narrowing, but socioeconomic inequalities are widening.

For example, cancer rates are generally highest among African-Americans and lowest for Asian-Americans. The cancer death rate in 2016 was 14 percent higher in blacks than in whites, which narrowed from 33 percent in 1993. 

A total of 1.77 million new cancer cases and 606,880 deaths from cancer are expected to occur in the United States in 2019, according to the American Cancer Society. While that may seem like a lot, the rate of new cancer diagnoses have actually decreased by about 2 percent per year in men and women, according to data from 2006 to 2015, the ACS reports. Additionally, the cancer death rate declined by 1.4 percent per year in women and 1.8 percent per year in men.

While these cancers are on the decline, incidence rates of other cancers, including melanoma and cancers of the thyroid and pancreas, are on the rise, U.S. News reports.

The report states that 71 percent of U.S. cases "are potentially preventable because most risk factors are modifiable." U.S. News explains further:

 But residents living in poorer counties, with double the prevalence of smoking and obesity as well as lower cancer screening prevalence and later-stage diagnosis, experienced a 20 percent higher overall cancer mortality rate than those in the most affluent counties between 2012 and 2016.
