Ductal carcinoma in situ (DCIS)

Short summary: DCIS is a non-invasive breast condition in which abnormal cells are found in the milk ducts. It has not spread beyond the duct lining, but it still requires proper evaluation and treatment planning.

Basic information about ductal carcinoma in situ (DCIS)

DCIS is often found on mammography before it causes symptoms. Some people never notice a lump or visible change, which is why screening can be important. ^[1][2]

Diagnosis usually involves imaging and biopsy. Treatment may include surgery, and in some cases radiation therapy or hormone-related treatment depending on the characteristics of the lesion and the overall care plan. Follow-up matters because the goal is to reduce the risk of recurrence or progression. ^[1][2][3]

Short conclusion: DCIS is not the same as invasive breast cancer, but it should not be ignored. Individual treatment decisions depend on pathology, imaging findings, and patient factors. ^[1][2]
