More than half a million deaths from breast cancer averted in the United States in three decades

The latest US estimates indicate that since 1989, hundreds of thousands of women have been saved through mammography and improved bad cancer treatment. Posted online early in Cancer, a peer-reviewed journal of the American Cancer Society, the findings highlight advances in the early detection and management of bad cancer.

Screening mammography for bad cancer detection became widely available in the mid-1980s and various effective treatments have been developed since then. To estimate the number of bad cancer deaths averted since 1989 due to the collective effects of screening mammography and improved treatment, R. Edward Hendrick, Ph.D., of the Faculty of Medicine at the University of Toronto University of Colorado, Jay Baker, MD, of Duke University Medical Center and Mark Helvie, MD, of the University of Michigan Health System, badyzed data on bad cancer mortality and population in American women aged 40 to 84 over the last three decades.

The total number of bad cancer deaths averted between 1990 and 2015 ranged from 305,000 women to more than 483,000 women, according to different mortality badumptions. Extrapolating results to 2018, the cumulative number of bad cancer deaths averted since 1989 ranged from 384,000 to 614,500. In 2018 alone, 27,083 to 45,726 bad cancer deaths were averted. The investigators calculated that mammography and improved treatment reduced the expected bad cancer mortality rate in 2018 from 45.3% to 58.3%.

"Recent mammography screening exams have drawn media attention to some of the risks of mammography screening, such as additional imaging reminders and bad biopsies, thus minimizing the most important aspect of mammography screening. screening shows that early detection of bad cancer saves women's lives.Our study demonstrates how the combination of early detection and modern bad cancer treatment has helped prevent cancer deaths in Canada. bad, "said Dr. Hendrick.

He noted that currently, only about half of American women over 40 are undergoing regular screening mammography. "The best possible long-term effect of our findings would be to help women recognize that early detection and modern personalized bad cancer treatment save lives and encourage more women." to be screened every year from the age of 40. "

Mr. Helvie added that research would likely continue. "As we anticipate new scientific breakthroughs that will further reduce bad cancer mortality and morbidity, it is important that women continue to adhere to existing screening and treatment recommendations," he said.
