Types of invasive breast cancers

Triple-negative breast cancer is an invasive breast cancer that is hard to treat. About 15 percent of all breast cancers are triple-negative breast cancer.

Inflammatory breast cancer is a rarer type of invasive breast cancer. Roughly 1 to 5 percent of all breast cancers are inflammatory breast cancer.

Rare breast cancers that affect other types of cells in the breast, which are more aggressive and more challenging to treat:

Paget’s disease of the breast accounts for about 1 to 3 percent of all breast cancers.

Angiosarcoma accounts for about 1 percent of all breast cancers.

Phyllodes tumors make up less than 1 percent of all breast tumors, and the majority of them aren’t cancerous. However, these tumors tend to fall into one of three categories: benign (non-cancerous), malignant (cancerous) or borderline .

When breast cancer spreads out of the breasts and beyond nearby lymph nodes into other parts of the body, like the bones, lungs, liver or brain, it’s called metastatic, the most advanced breast cancer stage.

Breast cancer types may also be differentiated by other factors, which help determine the treatments that are most likely to work. Your doctor will identify these factors to come up with the most appropriate treatment plan for you. These factors include:

Where in the breast the cancer begins: Breast cancer may start in the ducts, the lobules or elsewhere in the breast

Hormone receptor status: Hormone receptor status refers to whether breast cancer cells have specific proteins that act as “receptors” and attach to the hormones estrogen and progesterone. If a patient’s breast cancer cells have hormone receptors, then the cancer is hormone receptor-positive, which means the hormones estrogen and progesterone are responsible for fueling the cancer’s growth. If there are no receptors, the cancer is hormone receptor-negative. Hormone receptor status is determined by testing breast cancer cells that are removed during a biopsy or surgery. A cancer’s hormone receptor status will influence how it’s treated.
