Cancer death rates in the United States have declined to 25 percent (2.1 million) between 1991 and 2014. This is due to steady reductions in smoking, advances in early detection and treatment, says a new report.
According to 'Cancer Statistics 2017' annual report of the American Cancer Society, the cancer death rate dropped from its peak of 215.1 (per 100,000 population) in 1991 to 161.2 (per 100,000 population) in 2014.
The death rates decreased for the four major cancer sites: lung (-43 percent between 1990 and 2014 among males and -17 percent between 2002 and 2014 among females), breast (-38 percent from 1989 to 2014), prostate (-51 percent from 1993 to 2014) and colorectal (-51 percent from 1976 to 2014).
While the overall cancer incidence rate was stable in women and declined by about two per cent per year in men, the cancer death rate decreased by about 1.5 percent annually in both men and women.
In addition, the report found significant gender disparities -- the cancer incidence rate is 20 percent higher in men than in women, while the cancer death rate is 40 percent higher in men.
Liver cancer -- a highly fatal cancer -- was found to be three times more common in men than in women.
While the incidence and death rates of cancers of the esophagus, larynx and bladder, were found to be about four-fold higher in men, the incidence rates of melanoma -- skin cancer -- were about 60 percent higher in men than in women and death rates were more than double in men compared with women, the researchers stated.
The report was published in CA: A Cancer Journal for Clinicians.
