Breast Cancer

How Breast Cancer Spreads

The first place cancer is found in the body is called the primary site or primary tumor. Breast cancer, like all cancers, can spread to other parts of the body. This is called metastatic cancer, or metastasis. When a cancer spreads, it is said to have metastasized.
The first place that breast cancer usually spreads to is the nearby lymph nodes under your arms. In some cases, it spreads to distant parts of the body, like your liver. It may also spread to your skin. Although the cancer has spread, it's not considered a new cancer. For instance, if breast cancer spreads to your liver, it is not considered liver cancer. It's called metastatic breast cancer.
