Invasive breast cancer means the tumor cells have grown from its initial site into nearby breast tissue. It can also spread to lymph nodes and other distant areas of the body. Another name for this type of cancer is infiltrating breast cancer.
There are two types of invasive breast cancer. The first is invasive ductal carcinoma (IDC), which starts in the milk ducts. It is the most common form of breast cancer. The other is invasive lobular carcinoma (ILC), which starts in the breast lobules. Breast lobules are sacs that produce milk. ILC is the second most common form of breast cancer.
