What should you know about focal ductal carcinoma in situ?

Focal means the abnormal area is limited to a defined region. DCIS is found within the lining of a duct and has not grown through the duct wall at the time it is diagnosed. It is often detected on a Mammogram as tiny areas of calcium, although some people notice a lump, nipple change, or discharge. A symptom does not establish DCIS, and many breast changes are benign.

A Breast Biopsy examines cells or tissue from the area. The report may describe the grade, extent, and hormone-receptor features. Those details, together with breast imaging and personal priorities, shape the treatment discussion.

Your breast team may discuss Lumpectomy to remove the affected area, sometimes followed by Radiotherapy. Mastectomy may be considered when the area is extensive, involves more than one region, or cannot be removed while preserving a suitable breast shape. Hormone Therapy for Cancer can be discussed when the cells have relevant hormone receptors. Ask how the recommended option affects recurrence risk, breast appearance, recovery, and future imaging.

Contact the breast clinic if a new lump, nipple inversion, bloody discharge, skin dimpling, or a rapidly changing breast area appears. After a biopsy or operation, seek prompt advice for persistent bleeding, worsening swelling, fever, increasing redness, or drainage. Sudden breathlessness or chest pain needs emergency care.

Ask how large and localised the DCIS is, what the grade and receptor findings mean, which operation is suitable, whether radiotherapy is advised, and how follow-up imaging will be arranged.
