(CTN News) – As a result of breast cancer screening and treatment, the death ratebreast cancer in the United States has fallen by 58% between 1975 and 2019,
According to a study published in the Journal of the American Medical Association on Januaryoverall reduction in mortality by 58% since 1975.
As a result of aggregated observational and clinical trial data on the dissemination and effects of cancer screening and treatment, Jennifer L. Caswell-Jin, M.D., from Stanford University School of Medicine in California, and colleagues were able to simulate the relative association of cancer screening, treatment of stage I to III breast cancer, and treatment of metastatic breast cancer with improved mortality.
A study conducted by researchers in the United States found that age-adjusted mortality rates for cancer in the United States were 48 per 100,000 women in 1975 and 27 per 100,000 women in 2019.
It has been shown that the combination of screening, stage I-III treatment, and metastatic treatment reduced breast cancer mortality by 58% in 2019.
The reductions were associated with treatments of metastatic cancer, treatment of stage I to III breast cancer, and mammography screening, respectively; 29, 47, and 25% of those reductions were associated with treatment for metastatic cancer, treatment for stage I to III cancer, and mammography screening.
In terms of the change in survival over the period from 2000 to 2019 based on simulations, the most significant increase was from 1.9 to 3.2 years after a metastatic recurrence.
Based on the findings of this study, the authors write that advances in the treatment of metastatic cancer have been associated with a decrease in breast cancer mortality in the United States.
