Invasive lobular carcinoma (ILC) is an understudied subtype that occurs in about 10 to 15 percent of breast cancer patients and is known to be difficult to detect by imaging. So how do we approach diagnosing and treating this subtype? Dr. Pavani Chalasani is joined by Dr. Jason Mouabbi, Assistant Professor of Medicine at the University of Texas MD Anderson Cancer Center and Chair of the Lobular Breast Cancer Alliance, to discuss his session on ILC at the 2023 San Antonio Breast Cancer Symposium.
