U.S. Cancer Death Rates Decreasing Steadily

U.S. Cancer Death Rates Decreasing Steadily

Largest decrease seen among black men aged 40 to 49 years; no drop for white women aged over 80

TUESDAY, Jan. 7, 2014 (HealthDay News) -- Cancer death rates have been decreasing steadily for the past two decades, with the magnitude of the decrease varying with age, race, and sex, according to a report published online Jan. 7 in CA: A Cancer Journal for Clinicians.

Rebecca Siegel, M.P.H., from the American Cancer Society in Atlanta, and colleagues collected data on cancer incidence and mortality to estimate the number of new cancer cases and deaths that will occur in the United States in the current year.

The researchers note that 1,665,540 new cancer cases and 585,720 cancer deaths are projected for the United States in 2014. The delay-adjusted cancer incidence rates decreased slightly in the past five years (2006 to 2010) in men (0.6 percent per year) and remained stable in women. For men and women, cancer death rates decreased by 1.8 and 1.4 percent per year, respectively. The combined cancer death rate has been decreasing steadily for two decades, with a 20 percent decrease noted from 1991 to 2010, representing approximately 1,340,400 cancer deaths avoided during this time period. Considerable differences were seen in the magnitude of the decline in cancer death rates with age, sex, and race, ranging from no decrease among white women aged 80 years and older to a 55 percent decrease among 40- to 49-year-old black men.

"Further progress can be accelerated by applying existing cancer control knowledge across all segments of the population," the authors write.

Review Quantifies Benefits, Harms of Mammography

Review Quantifies Benefits, Harms of Mammography

Among 1,000 U.S. women screened annually for 10 years, 0.3 to 3.2 will avoid breast cancer death

FRIDAY, Jan. 3, 2014 (HealthDay News) -- The benefits and harms of screening mammography have been quantified in a special communication published online Dec. 30 in JAMA Internal Medicine.

H. Gilbert Welch, M.D., M.P.H., and Honor J. Passow, Ph.D., from the Dartmouth Institute for Health Policy and Clinical Practice in Hanover, N.H., provide a range of estimates for the absolute frequency of breast cancer deaths avoided, false alarms, and overdiagnosis associated with screening mammography. Data were used from nine randomized trials and are specific to the United States.

The researchers found that, among 1,000 U.S. women aged 50 years who underwent annual screening for 10 years, 0.3 to 3.2 will avoid a breast cancer death; 490 to 670 will experience one or more false alarms; and overdiagnosis and needless treatment will affect three to 14.

"We hope that these data are sufficient for some women to make the decision about whether or not to be screened," the authors conclude. "Some may choose to pursue screening, valuing any potential for benefit as warranting the accompanying harms. Others may choose not to pursue screening, valuing the plausible range for the magnitude of the harms as being too great to justify pursuing the relatively small benefit."
