When is radiotherapy recommended for ductal carcinoma in situ?

Ductal carcinoma in situ is abnormal cells confined to a milk duct. After surgery, radiotherapy treats the remaining breast tissue around the surgical site. The breast team reviews the operation report and pathology, including the lesion’s extent and whether the edges removed with it are clear. Some people may discuss surgery alone or another local plan, depending on their findings and preferences.

Ask for a clear explanation of the pathology and how it affects the recommendation. Tell the team about previous breast procedures, medicines and any implanted device. Before starting, ask how the breast will be positioned, how the skin may react, how to protect it, and whether the schedule can be coordinated with any further surgery or medicines.

Seek prompt medical advice for new breast redness with fever, rapidly increasing swelling, wound separation, drainage, severe pain, or a new lump after surgery. While receiving radiotherapy, contact the team if the skin becomes open, weeps, or becomes difficult to keep comfortable.

Ask why radiotherapy is advised in your case, which part of the breast will be treated, how the surgical margins affect the plan, and what alternatives are reasonable. Ask when follow-up imaging is due and which breast changes should be reported.
