As a non-profit organization, American Society of Clinical Oncology (ASCO) is dedicated to achieving its charitable mission outlined by the organization’s founders in 1964. ASCO strongly supports all types of cancer research, but in particular, patient-oriented clinical research.

More than 28,000 oncology practitioners belong to ASCO, representing all oncology disciplines (medical, radiological, and surgical oncology) and subspecialties. Members include physicians and health-care professionals participating in approved oncology training programs, oncology nurses, and other practitioners with a predominant interest in oncology.

As the world’s leading professional organization representing physicians who treat people with cancer, ASCO is committed to advancing the education of oncologists and other oncology professionals, and advocating for policies that provide access to high-quality cancer care.

In 2002, UICC accepted ASCO as a full member.
