Patient Information

Information for Patients with Lobular Breast Cancer

Also known as Lobular Breast Cancer, ILC is the 2nd most common subtype 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 due to the absence of the protein E-cadherin, making ILC much harder to detect with screening, advanced imaging, and self-exams.
  • Despite a generally good prognosis, some studies suggest an increased risk of late recurrence (after 5 years). Read more ILC Facts here.
The materials provided here were compiled for use by individuals with invasive lobular carcinoma (ILC) and their loved ones.

LBCA does not attempt to duplicate current information about general breast cancer available on other websites. LBCA provides specific information, including graphics and downloadable pdfs, about ILC and  treatment, and sample questions specific to lobular breast cancer that patients may wish to discuss with their care teams.  LBCA strives to keep this site current as new information and research findings become available.
