AACI's annual joint Hill Day with the American Association for Cancer Research (AACR) brings cancer center directors, researchers, physician-scientists, cancer survivors, and other advocates together to build support for a strong federal investment in biomedical research—and cancer research in particular—through the National Institutes of Health (NIH) and the National Cancer Institute (NCI). All faculty and staff of AACI cancer centers are invited to spend the day advocating for cancer research funding on Capitol Hill.
