The American Association for Cancer Research (AACR) is the world's oldest and largest professional association related to cancer research. Based in Philadelphia, the AACR focuses on all aspects of cancer research, including basic, clinical, and translational research into the etiology, prevention, diagnosis, and treatment of cancer. Founded in 1907 by 11 physicians and scientists, the organization now has more than 58,000 members in 142 countries and territories. The mission of the AACR is to prevent and cure cancer through research, education, communication, collaboration, science policy and advocacy, and funding for cancer research.2

The story

History

The AACR was founded on May 7, 1907, in Washington, D.C., as the "Association for Cancer Research" by a group of scientists consisting of four surgeons, five pathologists, and two biochemists. The founding members were Silas P. Beebe, George H. A. Clowes, William Coley, James Ewing, Harvey R. Gaylord, Robert B. Greenough, J. Collins Warren, George W. Crile, Leo Loeb, Frank Burr Mallory, and Ernest E. Tyzzer. They organized annual meetings to coincide with the meetings for the much larger meetings of the American Association of Pathologists and Bacteriologists. At the first meeting in New York City in November 1907, nine papers were presented. For the first 30 years, the group functioned as a select group of scientists, but with the expansion of cancer research in the 1930s, membership and interest grew. The society was officially incorporated in 1940.

The AACR Foundation for the Prevention and Cure of Cancer

The AACR Foundation for the Prevention and Cure of Cancer is a 501(c)(3) public charity that provides financial support for scientific research, education, and communication. The foundation funds programs deemed by the AACR to be of the highest priority and impact in promoting research, supporting scientists, and raising awareness. Eighty-eight cents of every dollar raised by the AACR Foundation directly supports cancer research.

Cancer Research is the second most-frequently cited cancer journal in the world. Papers are peer-reviewed, and only those that meet high standards of scientific merit are accepted for publication. The journal publishes significant, original studies, reviews, and perspectives on all areas of basic, clinical, translational, epidemiological, and prevention research in cancer and the cancer-related biomedical sciences. Some of the topics include biochemistry; chemical, physical, and viral carcinogenesis and mutagenesis; clinical research including clinical trials; endocrinology; epidemiology and prevention; experimental therapeutics, molecular targets, and chemical biology; immunology and immunotherapy including biological therapy; molecular biology, pathobiology, and genetics; radiobiology and radiation oncology; cell and tumor biology; tumor microenvironment; systems biology and other emerging technologies.
