What type of breast cancer is characterized by abnormal cells in the lining of the breast ducts?

• A. Invasive ductal carcinoma
• B. Ductal carcinoma in situ
• C. Invasive lobular carcinoma
• D. Paget's disease of the nipple

Answer: (B)

Ductal carcinoma in situ (DCIS) is characterized by the presence of abnormal cells confined to the lining of the breast ducts, which means the cells have not invaded surrounding breast tissue. DCIS is considered a non-invasive breast cancer because it does not have the potential to metastasize beyond the ducts where it originated. This stage of cancer is often detected through mammography and can appear as microcalcifications. The diagnosis of DCIS is significant because, while it is not life-threatening in itself, it can be a precursor to invasive breast cancer if left untreated. Understanding this condition is crucial for breast care nurses, as early detection and appropriate management can lead to improved outcomes for patients.
