My grandfather died of cancer. At that time, the situation was not optimistic. Cancer metastasized to the lung and brain. It is very important to prevent cancer metastasis. Let's look at the pathways of cancer metastasis.

What are the pathways of cancer metastasis

First of all: direct invasion direct invasion refers to the tumor cells directly invade the surrounding tissues, resulting in tumor enlargement and spread. In several ways of tumor metastasis, direct invasion is the most easily predicted because the tumor only involves the surrounding tissues.

Secondly: blood transfer as we all know, the human body is full of complex blood circulation system, like a highway extending in all directions, which continuously transports nutrition and oxygen to every part of the body. When tumor cells invade such blood vessels, they will quickly transfer to organs far away from the primary tumor with blood circulation, and then take root and germinate to generate new tumor metastases, which will cause corresponding harm.

Finally: lymphatic metastasis. Many people may have heard of the word "lymphatic system", but they have little understanding of its true meaning. In fact, in addition to the blood circulation system composed of heart and blood vessels, there is also a set of lymphatic system composed of lymph nodes and lymphatic vessels, which mainly plays the role of immune defense.
