Welcome to the LEAN Study!

The LEAN lifestyle intervention is designed specifically for breast cancer survivors. Based upon your results and feedback, we hope to make our LEAN program available for all breast cancer survivors.


In honor and in memory of our mothers, sisters, daughters and girlfriends who have shown unbelievable strength and resilience through their survivorship journey. We thank you for inspiring us and reminding us of the beauty of today.

Medical Disclaimer

The LEAN program should not replace any breast cancer treatment or any advice received from clinicians. The goal of the LEAN program is to complement any therapies, and in turn, improve lifestyle behaviors associated with better quality of life and longevity after a breast cancer diagnosis.

Supported by the American Institute for Cancer Research, Connecticut Breast Health Initiative, the Yale Cancer Center and the Breast Cancer Research Foundation. HIC# 1410014716.
