Final answer:
The mortality rate from breast cancer in the U.S. is decreasing due to early detection through mammograms, medical advancements in treatments, preventive care initiatives, and lifestyle changes.
Step-by-step explanation:
The mortality rate from breast cancer is falling in the United States due to several key factors. Early detection through routine screening such as mammograms has significantly increased the chances of catching breast cancer at a curable stage. Figure 21.7.4 highlights the importance of annual mammograms for women aged 50 and older in catching cancer early. Advances in medical treatments and a deeper understanding of the disease have also played a crucial role. The adoption of healthier lifestyle choices, increased awareness, and access to preventive care have contributed to the decline in deaths attributed to breast cancer.
Impact of Early Detection and Medical Advances
Cancer death rates, including breast cancer-specific mortality, have continuously declined for two decades as reported by Siegel in 2014. The combination of early detection, better screening programs, advancements in treatment, and increased public health campaigns have been effective in reducing fatalities.
