DCIS doesn't cause any signs or symptoms in most cases. However, DCIS can sometimes cause signs and symptoms, such as:
- A breast lump
- Bloody nipple discharge
DCIS is usually found on a mammogram.
When to see a doctor
Make an appointment with your doctor if you notice a change in your breasts, such as a lump, an area of puckered or otherwise unusual skin, a thickened region under the skin, or nipple discharge. Contact your doctor to have it evaluated.
Ask your doctor when you should consider breast cancer screening and how often it should be repeated. Most groups recommend routine breast cancer screening beginning in your 40s. Talk with your doctor about what's right for you.
