Question: what is the difference between invasive lobular carcinoma and invasive ductal carcinoma?
Answer: Invasive lobular carcinoma (ILC) ILC starts in the milk-producing glands (lobules). Like IDC, it can spread (metastasize) to other parts of the body. Invasive lobular carcinoma may be harder to detect on physical exam and imaging, like mammograms, than invasive ductal carcinoma.
