Types of Breast Cancer

Types of breast cancer include ductal carcinoma in situ, invasive ductal carcinoma, inflammatory breast cancer, and metastatic breast cancer.

Ductal Carcinoma In Situ (DCIS) DCIS is non-invasive, Stage 0 breast cancer that has not spread into other tissue or lymph nodes. DCIS is highly treatable.

Invasive Ductal Carcinoma (IDC) IDC is invasive breast cancer that began in the milk ducts and has spread into surrounding breast tissue or areas of the body.

Lobular Carcinoma In Situ (LCIS) LCIS is not breast cancer; it is a risk factor for developing breast cancer. It is a condition where abnormal cells are found in the breast lobules.

Invasive Lobular Carcinoma (ILC) ILC is invasive breast cancer that began in the milk glands (lobules) and has spread into surrounding breast tissue or areas of the body.

Triple Negative Breast Cancer TNBC is a rare but aggressive type of breast cancer that lacks the receptors commonly found in other types, impacting treatment options.

Male Breast Cancer While rare, men can also develop breast cancer. Male breast cancer is usually detected as a hard lump underneath the nipple or areola.

Inflammatory Breast Cancer (IBC) IBC is a rare but aggressive and fast-growing type of breast cancer that affects the skin of the breast, often causing a distinct rash.

Metastatic Breast Cancer MBC is Stage 4 breast cancer that has spread from the breast into other areas of the body, typically the bones, lungs, liver, and brain.

Breast Cancer During Pregnancy Pregnancy does not cause breast cancer, but treatment options may be different for women who are diagnosed during pregnancy.

Other Types Less common types of breast cancer include medullary carcinoma, tubular carcinoma, Paget’s disease of the breast, metaplastic breast cancer, and more.
