World Ovarian Cancer Day 2026

World Ovarian Cancer Day is observed on May 8. The 2026 theme, “No Woman Left Behind,” highlights unequal access to diagnosis and treatment, especially in low-resource countries. Ovarian cancer caused over 3.13 lakh new cases globally (GLOBOCAN 2020) and remains difficult to detect early due to vague symptoms. The campaign stresses awareness, early diagnosis, and improved healthcare access. Experts call for greater investment in research and equitable treatment to reduce the rising burden of this “silent disease.”
