Ductal carcinoma is a type of breast cancer which starts in the ducts of the breast which move the milk from the breast to the nipple. DCIS or ductal carcinoma in situ is a cancer where the lining of the milk ducts have not invaded the nearby tissues. However, they may progress if left untreated.Usually, DCIS does not show any symptom in the beginning. However, as the cancer grows, some symptoms may be observed such as:
- Lump in the breast or arm pit that is hard with uneven edges and painless.
- Change in the shape, size, and color of the nipple
- Watery fluid coming out from the nipple
