What Are FES PET Scans and How Are They Used for Lobular Breast Cancer? - Metastatic Breast Cancer Trial Talk

Research News

Lobular breast cancer is most commonly estrogen receptor positive (ER+) and spreads to different parts of the body compared to ductal breast cancer. Lobular breast cancer is also more difficult to detect with imaging scans. A PET scan is an imaging scan that uses a radioactive substance called a tracer that can look for and attach to cancer cells. For lobular breast cancer, researchers are investigating a tracer called FES, or [18F]fluoroestradiol, that detects estrogen receptors and allows doctors to see the cancer on the PET scan. The goal is that using FES as a tracer during PET scans will improve the detection of lobular breast cancer when it spreads.
