What to expect from a mammogram for ductal carcinoma in situ

Ductal carcinoma in situ begins in a milk duct and has not grown beyond the duct. It often has no obvious symptom, so mammography may draw attention to fine or clustered calcium deposits. The appearance can guide which additional images or biopsy approach is considered.

An imaging report may describe a finding as needing more assessment rather than giving a final diagnosis. The radiologist may request magnified views, an ultrasound, or comparison with earlier images. A biopsy provides tissue for laboratory examination.

Do not apply deodorant, powder, lotion, or talc to the chest or underarms before the scan. Wear clothing that is easy to remove from the waist up. Tell the team about implants, prior breast procedures, breastfeeding, pregnancy, or a painful area.

The radiographer will position each breast and take images from different angles. Compression can feel firm or uncomfortable for a short time. Tell the radiographer if you need a pause, and arrange how you will receive the report before leaving.

Keep the follow-up appointment even if you feel well, because ductal carcinoma in situ may not cause a noticeable change. Contact the team about a new lump, nipple discharge, skin change, or persistent focal pain. Urgent care is appropriate for severe breathing trouble or sudden collapse, not for ordinary post-imaging tenderness.

Ask what the calcium deposits look like, whether prior images were compared, whether a biopsy is advised, how the result will be communicated, and which treatment discussions follow a confirmed diagnosis.
