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 anticancer treatment to post-treatment care. Enhancing rehabilitation, secondary cancer prevention, survivorship and end of life care are integral to Supportive Care.

  • Alleviates symptoms and complications of cancer
  • Reduces or prevents toxicities of treatment
  • Supports communication with patients about their disease and prognosis
  • Allows patients to tolerate and benefit from active therapy more easily
  • Eases emotional burden of patients and care givers
  • Helps cancer survivors with psychological and social problems

The Multinational Association of Supportive Care in Cancer (MASCC) is an international, multidisciplinary organization with members representing over sixty (60) countries and five continents. MASCC is a tax-exempt 501(c) 3 corporation.
Founded in 1990, MASCC is dedicated to research and education in all areas of supportive care for patients with cancer, regardless of the stage of the disease. MASCC aims to promote professional expertise of supportive care through research and scientific exchange of ideas. Significant advances in cancer treatment have been made possible by the strides in supportive care.
Because supportive care encompasses all aspects of care, it involves a variety of disciplines and specialists. Thus membership is open to medical oncology, surgical oncology, radiation oncology physicians, nurses, dentists, dental hygienists, pharmacists, social workers, dietitians, outcomes specialists, psychologists, statisticians, infectious disease specialists, educators, representatives from industry and non-profit sectors, and others interested in supportive care.
Significant advances in cancer treatment in the last two decades have been made possible by the strides in supportive care.  MASCC/ISOO is dedicated to continuing this effort by providing a platform and resources for addressing the comprehensive, appropriate care to prevent, minimize, and treat side effects of cancer and its treatments.
