Metastatic

What is Metastatic?

Metastatic meaning Of or pertaining to metastasis, or the process by which malignant neoplasms can shed individual cells, which can travel through the lymph vessels or blood vessels, lodge in some distant organ, and grow into tumors in their own right. There are two major routes of metastasis1. Hematogenous, in which cells travel through the blood vessels.2. Lymphogenous, in which the lymphatic vessels conduct the cancer cells. In the case of lymphogenous metastasis, the metastatic tumors can grow from cancer cells entrapped in the lymph nodes that collect the lymph draining from the organ where the original cancer has developed, causing the nodes to enlrage.
