We are your breast cancer movement.
Rethink Breast Cancer empowers younger women to take charge of their breast health and is revolutionizing what it means to live with and beyond breast cancer. Rethink fosters community, shares credible information, fills gaps in care, and helps drive meaningful systemic change.
Visit the Rethink House Pop-up this October
This pop-up is a month-long experiential space for our community and the public to experience Rethink’s future vision, shop the 25 for 25 Collection, attend educational and community events and help fundraise for the permanent House. The Rethink House Pop-Up is powered by TELUS.

Boobyball is back!
Boobyball is what happens when we decide breast cancer doesn’t have to be bleak, fundraising doesn’t have to be boring, and showing up is the most powerful thing we can do. For one night on October 16, we celebrate that, while supporting Rethink’s mission to champion those left out of the spotlight.
