Ductal Carcinoma in Situ
Ductal carcinoma in situ is the earliest stage of breast cancer. It is noninvasive and starts in the tubes (ducts) of the breast that carry milk. It doesn’t spread outside of these tubes, meaning the risk of the cancer spreading to lymph nodes and to other parts of the body is much lower.
Lobular Carcinoma in Situ
Lobular carcinoma in situ, also known as lobular neoplasia, is a rare condition in which abnormal cells develop in the milk glands (lobules) in the breast. These abnormal cells are not considered to be breast cancer but do require surgical removal. The condition may increase the risk of breast cancer.
Invasive Ductal Breast Cancer
Invasive ductal breast cancer, also known as infiltrating ductal carcinoma, is the most common form of invasive breast cancer and represents 80 percent of breast cancer cases. The condition begins with abnormal cells forming in the milk ducts of the breast (ductal) and spreading into the surrounding fatty breast tissue (invasive).
Invasive Lobular Breast Cancer
Invasive lobular breast cancer, also known as infiltrating lobular carcinoma, is the second most common form of invasive breast cancer. It makes up 10 to 15 percent of breast cancer cases. The condition begins when abnormal cells develop in the milk gland, known as lobules, in the breast. These cancer cells then spread to other parts of the body.
