We are an international, interdisciplinary organization dedicated to the practice, education, and research of supportive care in cancer.

When you join MASCC, you become eligible to join up to three study groups devoted to specific topic areas in supportive care in cancer.
Evidence-based resources to support your work in supportive care
The future of supportive care in cancer is shaped at the MASCC/ISOO Annual Meeting.
We’re proud to work together with our affiliates and partners to reduce the burden of cancer worldwide.
“Ask, understand: Supportive care in cancer” is an AI-powered digital platform providing accurate, reliable information on supportive care in cancer for patients, caregivers, and clinicians
The information on the platform is sourced exclusively from verified, evidence-based resources available through the MASCC website, making it a trusted source for both patients and providers.
This platform was developed by Make.org. The project was made possible through financial support from La Roche-Posay, which had no influence over the content.
This tool provides educational information only and is not a substitute for medical advice. Always consult your healthcare team for personal medical guidance.
