Sometimes breast cancer cells spread to one or both lungs through the blood or lymph system. Itâs not uncommon for the lymph nodes of the chest (mediastinum) to be affected. The cells that have spread to the lungs are breast cancer cells. It is not the same as having cancer that starts in the lungs (a lung cancer). When breast cancer spreads to the lungs it can be treated but it can't be cured. The lungs sit on either side of the chest and are protected by the rib cage.
The lungs are the most common organ for cancers to spread to. This is because the blood from most parts of the body flows back to the heart and then to the lungs before it goes to any other organ. Cancer cells that have found their way into the bloodstream can get stuck in the tiny blood capillaries of the lungs.
