These secondary cancers are identified by the site of origin; thus, a breast cancer metastasis to the lung is still known as breast cancer. They often have a characteristic round appearance on chest radiograph. In children, the majority of lung cancers are secondary.Primary lung cancers themselves most commonly metastasize to the adrenal glands, liver, brain, and bone.
