The sampling included women ages 20 to 44 years who were diagnosed from 2004 to 2010 in the Seattle-Puget Sound metropolitan area:
• 779 with estrogen receptor-positive breast cancer
•182 triple-negative breast cancer
• 60 with ER-negative/HER2-overexpressing, invasive breast cancer
• 939 cancer-free controls.
This supports a fairly large body of research that has associated weight gain with TNBC risk.
Read more about BMI and TNBC, plus a roadmap for a healthy lifestyle, in my book, Surviving Triple-Negative Breast Cancer.
