The Multinational Association of Supportive Care in Cancer (MASCC) is an international, interdisciplinary organization dedicated to the practice, education and research of supportive care in cancer. Our mission is to continually improve the supportive care of people with cancer – from diagnosis through to survival or end-of-life care.

MASCC 2026 – Save the date! The MASCC/ISOO Annual Meeting is the leading international, interdisciplinary event dedicated to supportive cancer care. Our 2026 theme—Coordinated and Individualized Supportive Cancer Care—reflects our commitment to advancing care that is both evidence-based and patient-centered.
