Extends the authority of the U.S. Postal Service to issue a breast cancer research stamp until 2037.

The Breast Cancer Research Stamp Reauthorization Act of 2026 amends title 39 of the United States Code to extend the authority of the U.S. Postal Service to issue a semipostal stamp for breast cancer research. This extension allows the Postal Service to continue raising funds for breast cancer research through the sale of these special stamps. The current authorization was set to expire in 2027, but this bill extends it by an additional ten years, until 2037.
