Ductal carcinoma in situ (DCIS) breast cancer

Ductal carcinoma in situ (DCIS) is the earliest form of breast cancer.
It is also called precancerous, intraductal or non-invasive. This means that cancer cells have formed inside the milk ducts but not spread outside them. Most people have no symptoms at all and are usually diagnosed from a mammogram (breast X-ray).

For more information on Invasive ductal breast cancer, see our Ductal carcinoma in situ booklet.
