U.S. research team: “Annual screening significantly reduces breast cancer mortality compared to biennial screening.”

(Seoul = Larose.VIP) Reporter Lee Joo-young = Research has shown that annual breast cancer screening from the age of 40 to at least 79 is the best way to minimize the risk of breast cancer and reduce mortality.

Professor Debra Monticciolo’s team at Dartmouth Geisel School of Medicine in Hanover, New Hampshire, USA, came to this conclusion in a comparative study of four breast cancer screening recommendations used in the United States in the Radiology Society of North America (RSNA) journal Radiology on the 21st. He said.

Breast cancer is the second most common cause of cancer death among American women. Although research shows that breast cancer screening can reduce mortality by up to 40%, it is known that less than 50% of women eligible for screening receive screening every year.

Professor Monticiolo said, “After the United States Special Task Force on Preventive Diseases (USPSTF) recommended screening every other year starting at age 50 in 2009, participation in screening has decreased.” He added, “There has been a decline in breast cancer screening recommendations, especially when to start screening and how often it should be done. “The debate continues,” he explained the background of the research.

Last year, the USPSTF issued a new recommendation requiring people between the ages of 40 and 74 to get screened every other year. In contrast, the American College of Radiology (ACR), the Society of Breast Imaging (SBI), and the National Comprehensive Cancer Network (NCCN) recommend that women at average risk for breast cancer undergo annual screening starting at age 40.

Using the ‘Cancer Intervention-Surveillance Modeling Network’ (CISNET) statistical model, the research team came up with four screening recommendations: ▲ biennial screening for ages 50 to 74 ▲ biennial screening for ages 40 to 74 ▲ annual screening for ages 40 to 74 ▲ annual screening for ages 40 to 79 The effects were compared and analyzed.

As a result, annual screening using digital mammography or tomosynthesis from the age of 40 to 79 resulted in a 41.7% reduction in mortality due to breast cancer, which was the largest among the four recommendations.

In comparison, the biennial examination for those aged 50 to 74 and the biennial examination for those aged 40 to 74 were analyzed to reduce mortality by 25.4% and 30%, respectively.

In addition, the ‘annual screening for ages 40 to 79’ had a false positive rate of 6.5%, in which non-breast cancer cases were diagnosed as cancer in mammography, and the rate of biopsies performed when it was not malignant was 0.9%. It was lower than the false positive rate (6.5-8.5%) of annual screening for ages ~74 years and the rate of biopsy for non-malignant cases (0.9-1.3%).

Professor Monticciolo said, “The biggest implication of this study is that breast cancer can be prevented and mortality rate reduced the most if you get screened every year starting from the age of 40 and until at least 79 years old.” He added, “If you continue to get screened after the age of 79, the benefits will be greater.” “It is,” he said.

“I hope primary care doctors recognize that the risks of screening are manageable and the benefits are enormous,” she said. “The literature adds that the best way to detect breast cancer early is to get screened every year starting at age 40.” “I hope so,” he added.
