Advocacy In Action

The Every Woman Study™

The World Ovarian Cancer Coalition is currently conducting the Every Woman Study Low- and Middle Income Edition to document the experiences of women with ovarian cancer in up to 30 low- and middle-income countries from pre-diagnosis through post-treatment. The IGCS and its members are assisting in the dissemination of the survey and results are expected in the second half of 2023. 

It is expected that the study will reveal data to better understand the landscape of ovarian cancer care and inform future strategies to close the care gap, driving earlier detection and enhancements in ovarian (and gynecologic) cancer care worldwide.

In 2022, IGCS embarked on an initiative — Project GEOCC (Global Equality in Ovarian Cancer Care) — to assess and address ovarian cancer care at a global level. Data collected from 1,509 specialists in 115 countries highlight the inequities in ovarian cancer care worldwide by helping us to understand current practices and the availability of treatment modalities worldwide. 

The workgroup manuscript is in progress, and we plan to share the findings and recommendations at the 2023 IGCS Annual Global Meeting in Seoul.
