What is the most common Breast Cancer?
Ductal Carcinoma is the most common type of breast cancer. There are two types: Ductal Carcinoma In Situ (DCIS)which is considered a pre-malignancy of the breast and there is Invasive Ductal Carcinoma of the breast.
The ducts refer to milk ducts. This type of cancer comes from the lining of a milk duct within the breast. These ducts carry milk from the lobules where the milk is made.
