When is mammogram recommended for ductal carcinoma in situ?

Ductal carcinoma in situ involves abnormal cells within a breast duct. It may be found as calcifications on a mammogram even when there is no palpable lump. Mammography can map the area and help the team consider whether further views, ultrasound, magnetic resonance imaging or a biopsy is needed. A biopsy examines tissue and is used to establish the diagnosis; an image alone cannot provide every detail needed for treatment.

Attend the requested imaging and bring details of prior breast investigations, procedures, implants and medicines. Ask whether the mammogram is diagnostic rather than routine screening and whether both breasts will be assessed. Keep the appointment where the images and pathology are reviewed together. The treatment plan may involve breast-conserving surgery, mastectomy, radiotherapy or monitoring decisions depending on the individual findings.

Tell the breast team promptly about a new lump, nipple discharge, skin change, persistent redness or worsening pain while DCIS is being assessed or treated. These symptoms do not identify the cause, but they should not wait for a routine discussion. Seek urgent care for severe breathing difficulty, fainting or sudden serious illness.

What did the mammogram show, and which area needs attention? Do I need additional views or a biopsy? How will the imaging findings affect surgery or radiotherapy? What follow-up imaging will be part of my plan?
