The Know Your Lemons Foundation is an internationally-recognized breast health charity, dedicated to empowering individuals around the world with life-saving breast cancer education. Through innovative and approachable resources, we seek to demystify breast health, eliminate fear and ensure that breast cancer awareness and early detection knowledge is available to everyone, no matter their gender, language or educational background.

Dr. Corrine Ellsworth-Beaumont, PhD MFA is a designer turned health educator, and the visionary behind the Know Your Lemons Foundation. After losing her grandmothers and a close friend to breast cancer, Dr. Beaumont wanted to do something that could save the lives of others. So she put her design skills to work, pursued her PhD in visual information design, and developed the iconic Know Your Lemons campaign. Today, she leads the Foundation with the goal of making breast cancer education clear, accessible and universal. Her work has been featured in the media globally and she has been recognized for her innovative approach to breast cancer awareness, including designing the KnoYour Lemons app which was named the best health and fitness app in the world by the Webby Awards in 2025.
