The Jeanette Acosta Invest in Women's Health Act of 2026 aims to expand women's access to cancer screenings, particularly for breast, cervical, ovarian, uterine, vaginal, and vulvar cancers. The bill establishes three main programs: grants to women's health care providers and essential community providers to expand preventive screening services; a demonstration training program to educate physicians, nurse practitioners, and other providers in cancer screening and culturally competent care; and a pilot project testing coordinated human papillomavirus and cervical cancer screening among high-risk populations. The legislation authorizes $20 million annually for fiscal years 2027 through 2029 for the screening expansion grants. The bill requires the Secretary of Health and Human Services to study cancer screening access across the United States and report to Congress within two years and every five years thereafter, with analysis of screening rates by geography, race, income, and insurance status, particularly for women of color and underserved populations who experience disproportionately higher cancer mortality rates.
