Solid DCIS

DCIS is confined to the lining of a milk duct. The word solid describes how the cells are arranged under the microscope; it does not by itself describe tumour size or severity. DCIS may be found on a mammogram before a lump or other symptom appears. A breast biopsy provides tissue for the pathologist to examine, and the report may also describe cell grade, hormone receptors, necrosis, and the area involved.

Your breast team will review the mammogram, examination, and biopsy findings together. Treatment commonly involves removing the area with a lumpectomy or removing more breast tissue with a mastectomy, depending on the extent and location. Radiotherapy may follow breast-conserving surgery. Hormone therapy for cancer may be discussed when the cells have hormone receptors. The choice depends on the pathology report, breast size, personal preferences, and whether clear margins can be achieved.

Arrange follow-up with the breast team so the biopsy result and treatment choices are reviewed without unnecessary delay. Seek urgent medical help for heavy bleeding, rapidly increasing breast swelling, severe pain, fever after a procedure, or trouble breathing. A new breast change should be assessed even when a previous scan was reassuring.

Ask whether the biopsy confirms solid DCIS, what grade and hormone-receptor findings were reported, and whether the margins or imaging show a wider area. Ask why lumpectomy, mastectomy, radiotherapy, or hormone therapy is being recommended and what follow-up will involve.
