Understanding your Pathology Report: 1. Non-Invasive or Invasive
[Slide 2] - Normal cells.
Non-invasive [Slide 3] - cancers that stay within the milk ducts or lobules in the breast, where they started. They do not grow into or invade normal tissues within or beyond the breast. Non-invasive cancers are sometimes called carcinoma in situ (“in the same place”) or pre-cancers.
Invasive [slide 4] - cancers that do grow into normal, healthy tissues, turning them cancerous. Most breast cancers are invasive.
Ductal - affecting cells in the passages between the milk producing centers and the nipples.
Lobular - affecting cells in the milk-producing centers of the breast.
In Situ - Non-invasive.
