Breaking down AGEs: Insight into how lifestyle drives ER-positive breast cancer

Consumption of processed foods high in sugar and fat increase levels of advanced glycation end products (AGEs). Researchers report that AGE levels are higher in patients with estrogen receptor (ER)-positive than ER-negative breast cancer. Addition of AGEs caused breast cancer cells, whose growth had previously been controlled by tamoxifen, to begin to grow again. This suggests that patients with high AGEs may be less likely to respond to tamoxifen treatment.
