Breast Cancer

If you've been diagnosed with breast cancer, the first step your doctor may take is to find the specifics of the tumor to determine your breast cancer type. This information can help guide your treatment. Breast cancer can begin in different areas of the breast:

• The milk ducts (ductal carcinoma)
• The lobules (lobular carcinoma)
• The connective tissue within the breast

Nearly all breast cancers are either ductal carcinomas or lobular carcinomas.
