Lobular carcinoma in situ (LCIS) may be present in one or both breasts, but it usually isn't visible on a mammogram. The condition is most often diagnosed as an incidental finding when you have a biopsy done to evaluate some other area of concern in your breast.
Types of breast biopsy that may be used include:
- Fine-needle aspiration biopsy. Your doctor directs a very fine needle into the breast. Next, your doctor uses a syringe attached to the needle to collect a sample of cells or fluid for examination.
- Core needle biopsy. A radiologist or surgeon uses a thin, hollow needle to remove several tiny tissue samples. Imaging techniques, such as mammography, ultrasound or MRI, are often used to help guide the needle used in a core needle biopsy.
- Surgical biopsy. A surgeon may perform an operation to remove a portion of the breast for examination.
