Each May, the American Association for Cancer Research (AACR) celebrates National Cancer Research Month, which recognizes the importance of cancer research and the contributions of researchers, physician-scientists, survivors, and patient advocates across the United States who are dedicated to the conquest of cancer. 

​The AACR brings together more than 37​,000 of the world's top researchers, health care professionals, and advocates to untangle cancer's complexities. Learn how you can help us uncover the clues to tomorrow's cures, so millions more can live cancer-free.

You can call on Congress​ to make cancer research a top national priority. Robust, sustained, and predictable federal funding is crucial for researchers to plan and continue the cutting-edge projects that will lead to new, better treatments and cures for a variety of diseases, including the more than 200 diseases we collectively call cancer.
