Metastatic tumor indicates that primary malignant tumor foci exist in human body, and metastasize to other organs in distant places through different ways, such as blood transfer, lymphatic transfer and implantation transfer.
Malignant tumors are highly invasive and easy to metastasize, for example, lung cancer patients can metastasize to brain, bone, liver and other parts of the body, and the metastasis mainly spreads to distant places through blood metastasis, while gastric cancer can also metastasize to clavicular lymph nodes, and can be metastasized through lymphatic metastasis.
And the tumor that metastasizes to other parts or other organs is called metastatic tumor. Patients with metastatic tumor usually have their condition developed to the middle and late stage, and patients have to be timely treated by surgery, radiotherapy and chemotherapy.
