Infiltrating Lobular Carcinoma

This type of cancer starts in the milk passage, or duct, of the breast, then the cancerous cells break through the wall of the duct and spread into the surrounding breast tissue. The cancer cells can then spread into lymphatic channels or blood vessels of the breast and to other parts of the body (known as “to metastasize”). IDC is considered to be the most common type of invasive breast cancers, making up about 80% of all breast cancers.
