Lung Metastases

About 60% of people diagnosed with metastatic breast cancer have lesions in either the lungs or the bones. Triple-negative disease is more likely than other types of breast cancer to metastasize to the lungs.

If breast cancer cells reach the lungs, they can multiply and create tumors that can affect how your lungs work. It’s possible to have just one tumor in the lungs, but most people who get lung metastases develop more than one tumor there.
