Invasive breast cancer, or infiltrating breast cancer, has spread from where it started into nearby tissue. In later stages of breast cancer, this can include lymph nodes and other areas of the body.
Invasive ductal carcinoma (IDC) is the most common type of breast cancer. It starts in the milk ducts. Invasive lobular carcinoma (ILC) begins in the breast lobules and is the second most common type.
