Breast cancer types

There are several different types of breast cancer. To determine an appropriate approach to treating the disease, your doctor will first evaluate the specifics of the breast tumor, including:

  • If the disease has spread beyond the breast
  • The type of tissue where the disease began

Lobular carcinoma

Lobular carcinoma begins in the lobes or lobules (glands that make breast milk). The lobules are connected to the ducts, which carry breast milk to the nipple.

Lobular carcinoma in situ (LCIS):

It begins in the lobules and does not typically spread through the wall of the lobules to the surrounding breast tissue or other parts of the body. While these abnormal cells seldom become invasive cancer, their presence indicates an increased risk of developing breast cancer later. About 25 percent of women with LCIS will develop breast cancer at some point in their lifetime. This subsequent breast cancer may occur in either breast, and may appear in the lobules or in the ducts.

  • Lobular carcinoma in situ treatment options: Because LCIS is not actually cancer, treatment may not be recommended. If you are diagnosed with lobular carcinoma, you may want to discuss more frequent breast cancer screening with your doctor. Increasing surveillance can help ensure that any subsequent breast cancer is detected in its earliest, most treatable stages.

Invasive lobular carcinoma (ILC):

It starts in the lobules, invades nearby tissue and can spread (metastasize) to distant parts of the body. This breast cancer type accounts for about 1 out of 10 invasive breast cancers.

  • Invasive lobular carcinoma treatment options: The treatment options for invasive lobular carcinoma include localized approaches such as surgery and radiation therapy that treat the tumor and the surrounding areas, as well as systemic treatments such as chemotherapy and hormonal or targeted therapies that travel throughout the body to destroy cancer cells that may have spread from the original tumor.
