The Massachusetts Society of Clinical Oncologists is a statewide association of oncologists and physicians who treat cancer patients.  Since its establishment in 1985, MSCO has been dedicated to safeguarding and improving the quality of cancer care and treatment in Massachusetts through professional education, advocacy, and patient awareness and resources. As a state affiliate of the American Society of Clinical Oncology, MSCO comprises more than 1,000 hematologists and oncologists from a variety of specialties from over 70 Massachusetts practices. Today, the need for a recognized, credible, cohesive, local "Voice of Oncology" to fight for the progress of cancer therapy remains.
