Metastasis is a secondary tumor that arises from tumors of various types and has differences from the primary malignant formation. The metastatic process can occur both at the site of the main tumor and in other parts of the body, and in these cases, organs or tissues experience varying degrees of damage.
In this case, metastases usually have a certain morphological structure and growth characteristics.
Types of metastasis There are two mechanisms of metastasis: lymphogenous and hematogenous. The lymphogenic mechanism is that the affected cells enter the lymphatic vessels and then travel throughout the body, carrying malignant cells to other organs and tissues. The hematogenous method occurs when cancer cells clog small arteries and are carried into the blood. As they move through the body's vascular system, they are deposited in the organs where they reach.
