De Know Your Lemons Foundation is een internationaal erkende liefdadigheidsinstelling op het gebied van borstgezondheid, toegewijd aan het geven van levensreddende voorlichting over borstkanker aan mensen over de hele wereld. Door middel van innovatieve en toegankelijke middelen proberen we borstgezondheid te demystificeren, angst weg te nemen en ervoor te zorgen dat kennis over borstkankerbewustzijn en vroegtijdige opsporing voor iedereen beschikbaar is, ongeacht geslacht, taal of opleiding.

Dr. Corrine Ellsworth-Beaumont, PhD MFA is a designer turned health educator, and the visionary behind the Know Your Lemons Foundation.

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 Know Your Lemons app which was named the best health and fitness app in the world by the Webby Awards in 2025.
