Ductal carcinoma in situ (DCIS) is one of the most common non-invasive ductal breast cancers. The reason is classified as a non-invasive cancer because it does not spread from the milk duct to the surrounding breast tissues. Ductal carcinoma in situ is not life-threatening, but it will increase the risk of developing invasive breast cancers. The disease generally does not cause obvious symptoms and signs. Some patients may have breast lumps or nipple discharge. Common method of treatment is breast-conserving surgery combined with postoperative radiotherapy. In some cases, the entire breast tissue needs to be removed.
