•DCIS – Ductal Carcinoma In Situ
Ductal Carcinoma In Situ is 98 to 99 percent curable. It refers to breast cancer that’s in the breast’s milk ducts, the tiny tubes that bring milk from where it’s manufactured (in the lobules) to your nipple.
•LCIS – Lobular Carcinoma In Situ
Lobular Carcinoma In Situ is NOT cancer. But it’s a sign that the woman who has it is 6 to 7 more times likely to develop cancer, over the course of her lifetime, than a woman who doesn’t have LCIS: the same risk you’d be at if your mother and sister both had cancer.
Invasive Types of Breast Cancer
•IDC – Invasive/Infiltrating Ductal Carcinoma
Infiltrating Ductal Carcinoma is the most common type; 70% of women with breast cancer have this diagnosis. And 80% of women with invasive breast cancer have IDC.
•ILC – Invasive/Infiltrating Lobular Carcinoma
Infiltrating Lobular Carcinoma occurs in the milk-producing lobules. While most breast cancer (86% of all breast cancer) occurs in the ducts, just 12% occurs in the lobules. Lack of a palpable lump is one aspect of lobular cancer distinguishing it from ductal.
Other Types of Breast Cancer
•Recurrent Breast Cancer
Breast cancer recurrence is generally more serious than a new breast cancer, as it indicates the cancer wasn’t knocked out by the initial treatment, and thus is inherently a “tougher” cancer.
•Inflammatory Breast Cancer and Paget’s Disease
