Lobular carcinoma is a type of breast cancer that first occurs in the breast lobules (milk producing sacs). When this type of cancer spreads to other tissues, lymph nodes, or beyond the breast, it is called invasive lobular carcinoma (ILC).
Compared to other types of breast cancer, lobular carcinoma more often starts as many tumors in both breasts. However, lobular carcinoma in situ (LCIS) is a noninvasive form of lobular carcinoma. This precancerous finding is uncommon. LCIS has no symptoms, and it does not usually show up on a mammogram. In most cases, doctors find LCIS as a result of a biopsy for another breast condition.

Lobular carcinoma is the second most common type of breast cancer. There are many things that increase your risk for breast cancer, most of which are out of your control.
Common risk factors for lobular carcinoma include:
Unlike other forms of cancer, lobular carcinoma does not appear as a lump with well-defined borders. Instead, look for changes in the breast. Signs to look for include:
If you experience changes in your breast that seem suspicious, your doctor will likely recommend taking a sample of cells, known as a biopsy. Your biopsy results can tell your doctor if cancer is present, as well as the the type, grade, HER2 status, and hormone receptor status of any cancer cells. This information will guide your doctor in creating a treatment plan specifically for you.
The stage of your cancer will determine the extent of your treatment. The main treatment for ILC is surgery — either lumpectomy or mastectomy. A lumpectomy removes only the tumor while a mastectomy removes the entire breast. Following a lumpectomy your doctor will probably recommend radiation therapy. Other treatments for ICL include:
Because it is precancerous, LCIS is treated in a different way. Your doctor will most likely suggest watchful waiting. Depending on your case, hormone therapy or prophylactic (preventive) mastectomy may be necessary to prevent breast cancer.
