The American Cancer Society (ACS) provides free Online Continuing Medical Education (CME) for physicians and other health care professionals. Although developed to help professionals maintain and improve their knowledge of cancer prevention, detection, diagnosis, treatment, and palliative care, ACS CME material may be viewed by any Web user.

ACS CME consists of journal-based activities and quizzes from CA: A Cancer Journal for Clinicians, as well as multimedia activities based on ACS guidelines for prevention and early detection of cancer. Such features as online scoring of quizzes, automatic tracking of CME credit hours earned, and printable certificates make the ACS CME experience convenient and efficient.
