Final answer:
Major organs affected by hematogenous metastasis include the brain, lungs, bones, and liver. Hematogenous spread means that cancer cells travel through the bloodstream to form new tumors in these organs.
Step-by-step explanation:
The organs commonly metastasized by hematogenous spread include the brain, lungs, bones, and liver. When cancer cells travel through the bloodstream from a primary tumor, they may form new tumors called metastases in these distant sites. Specific types of cancers tend to metastasize to particular organs; for example, lung cancer often spreads to the brain, bone, and adrenal gland, while metastasized breast cancer frequently grows in the bone, brain, and liver.
