Does mammogram treat ductal carcinoma in situ?

Ductal carcinoma in situ, or DCIS, is abnormal cell growth confined to a breast duct. It may appear on a mammogram as a cluster or pattern of calcifications, even when there is no lump. Imaging can help locate the area and support follow-up, but it cannot remove the abnormal cells. A biopsy is commonly used to confirm what the imaging finding represents.

Discuss the mammogram report with the breast team and complete any recommended diagnostic views or biopsy. If DCIS is confirmed, the team will consider factors such as the affected area and tissue findings when discussing surgery and any additional treatment. Keep copies of reports and ask when the next appointment or test is expected.

Contact the breast service promptly if you cannot attend a recommended follow-up or if a new breast change develops. After a biopsy or other procedure, seek urgent advice for fever, increasing redness, heavy bleeding, severe pain, or swelling that is getting worse.

Ask whether the finding needs a biopsy, what the report says about its location, and which treatment options apply if DCIS is confirmed. Ask how follow-up imaging will be scheduled and which post-procedure symptoms are expected.
