Komen for the Cure "to expand breast cancer awareness and prevention among the same target population of women receiving care at PEPFAR-funded HIV service sites" has allowed "the wonderfully robust PEPFAR prevention and treatment platform, considered one of the great global health achievements in recent times, to be made available to a whole new type of prevention - in this case for a non-communicable disease (NCD)."
