Tests and diagnosis
By Mayo Clinic staffLobular carcinoma in situ (LCIS) may be present in one or both breasts, but 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 lump. 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 from the breast mass. 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 removes either a portion of the breast lump (incisional biopsy) or the entire breast lump (excisional biopsy, wide local excision or lumpectomy) for examination.
