The Multinational Association of Supportive Care in Cancer (MASCC) is a multidisciplinary organization dedicated to research and education of supportive care professionals worldwide. The mission of MASCC is to improve the supportive care of people with cancer, from diagnosis, through treatment and survival, to end of life. Founded in 1990, MASCC now includes members from more than 70 countries and 6 continents. 

Because supportive care encompasses all aspects of care, it involves a variety of disciplines and specialists. Membership is open to medical, surgical, and radiation oncologists, nurses, dentists, dental hygienists, pharmacists, social workers, dietitians, outcomes specialists, psychologists, statisticians, infectious disease specialists, educators, representatives from industry and nonprofit sectors, and others interested in supportive care. MASCC is a tax-exempt 501(c)(3) corporation.

In 1998, MASCC joined forces with the International Society of Oral Oncology (ISOO), an organization that addresses the management of complications arising in oral tissues secondary to cancer and its treatment.

What is Supportive Care?

Supportive care in cancer is the prevention and management of the adverse effects of cancer and its treatment. This includes management of physical and psychological symptoms and side effects across the continuum of the cancer experience: from diagnosis, through treatment, to post-treatment care. Enhancing rehabilitation, secondary cancer prevention, survivorship, and end-of-life care are integral to supportive care.

Benefits of Supportive Care

  • Alleviation of symptoms and complications of cancer
  • Prevention or reduction of treatment toxicities
  • Improved communication between patients and caregivers
  • Increased tolerance, and thus benefits, of active therapy
  • Easing of the emotional burden for patients and caregivers
  • Psychosocial support for cancer survivors
