The main purpose of this legislation, known as the "Screen to Save Act," is to ensure that women can receive annual screening mammograms at no cost starting at the age of 30. The bill aims to improve access to early detection of breast cancer, which can lead to better health outcomes. Key provisions of the Act include changes to Medicare, Medicaid, and private health insurance plans. Under Medicare, women over 29 will be eligible for annual mammograms without any out-of-pocket costs, starting January 1, 2027.
