What stage is invasive carcinoma? Generally, the stage of invasive ductal carcinoma is described as a number on a scale of I through IV. Stages I, II, and III describe early-stage cancers, and stage IV describes cancers that have spread outside the breast to other parts of the body, such as the bones or liver.
What is the difference between breast cancer and invasive breast cancer? Breast cancer usually begins inside the milk ducts or lobules of the breast tissue. Invasive breast cancer has spread from these areas to nearby breast tissue. After invading other healthy parts of the breast, an invasive cancer can travel to nearby lymph nodes.
What does invasive carcinoma mean? Cancer that has spread beyond the layer of tissue in which it developed and is growing into surrounding, healthy tissues.

Invasive ductal carcinoma (also called infiltrating ductal carcinoma) begins in the milk ducts and is the most common invasive breast cancer. Invasive lobular carcinoma begins in the lobules and is the second most common invasive breast cancer.
