Information About Lobular Breast Cancer

Lobular Breast Cancer, or invasive lobular carcinoma (ILC), is the 2nd most common type of breast cancer after invasive ductal carcinoma (IDC). 

  • About 15% of all breast cancers diagnosed in the U.S. each year are lobular.
  • One of the most unique features of most ILC tumors is the fact that they often do not form a lump, making ILC harder to detect with screening, advanced imaging, and self-exams.
  • Despite a generally good prognosis, some studies suggest there is an increased risk of late recurrence (after 5 years).
