Stamp Out Breast Cancer Act

Stamp Out Breast Cancer Act - Requires the U.S. Postal Service to establish a special rate of postage for first-class mail that is one cent higher than the regular rate as an alternative that patrons may use voluntarily to contribute to funding for breast-cancer research. Authorizes the Service to design and sell special stamps. Requires the Service to pay 70 percent of the amounts attributable (additional revenues minus costs) to the one-cent differential to the National Institutes of Health and the remainder to the Department of Defense under arrangements as mutually agreed, provided payments are made at least twice a year.
