Lobular carcinoma in situ (LCIS) doesn't cause signs or symptoms. Rather, your doctor might discover incidentally that you have LCIS — for instance, after a biopsy to assess a breast lump or an abnormal area, such as microcalcifications, 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.
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.
