How effective is lumpectomy for ductal carcinoma in situ?

Ductal carcinoma in situ is abnormal cell growth contained within a milk duct. Lumpectomy removes the area identified on imaging and examination, together with a surrounding tissue margin. The laboratory report confirms the diagnosis, measures the extent and checks the edges of the specimen.

The result is shaped by the size and distribution of the DCIS, its cell features, the margin, breast anatomy and whether radiation or hormone treatment is advised. If abnormal cells are close to an edge, the team may discuss another excision or a different operation.

Review the mammogram or other imaging with the breast surgeon and ask how much tissue is likely to be removed. Confirm whether a marker will guide the operation and when the final pathology discussion will occur.

Ask how radiation or hormone treatment could reduce the chance of DCIS returning in the treated breast, and whether these options fit your diagnosis. Keep follow-up imaging appointments because new breast changes can require assessment even after successful treatment.

After surgery, report fever, spreading redness, worsening swelling, increasing pain, unusual drainage, persistent bleeding or a wound that separates. Get urgent medical help for severe breathing difficulty, chest pain, fainting or heavy bleeding.

How extensive is my DCIS on imaging? Are the expected margins clear? Could I need another operation? Is radiation or hormone treatment advised, and what follow-up imaging schedule will I use?
