The Saudi Charitable Association for Cancer, known as Sudun, is a nonprofit organization dedicated to supporting people affected by cancer and advancing awareness and prevention in Saudi Arabia. Its work combines patient and family support with public education and access to early detection services. The association offers social services, psychological support, volunteer opportunities, and guidance through its patient-care system. Its early detection programs include the Abdulatif Early Detection Center, mobile clinics, and appointment booking for screening. Awareness campaigns, including breast cancer education during October, encourage people to learn about cancer and seek appropriate examinations.

Sudun also organizes activities for patients, survivors, and their families, such as educational events, psychosocial sessions, and celebrations recognizing patients’ treatment progress. It shares news, translated books, media materials, and financial reports through its website. The association works with health and media organizations; a reported partnership with the Eve One intravenous infusion center aims to strengthen treatment-related care for cancer patients.
