What are the symptoms of DCIS?
DCIS cannot usually be felt as a breast lump or other breast change.
Most cases of DCIS are found following routine screening with mammograms. DCIS often appears as small flecks of calcium (called microcalcifications) on a mammogram or ultrasound.
Most women with DCIS are not aware of any symptoms at the time of diagnosis.
