What are the metastasis pathways of lung cancer

summary

For lung cancer, we all know that if it is early detection, then the possibility of treatment is still great. But for advanced lung cancer, the cure is unlikely. Therefore, for lung cancer we should do early detection, early treatment, so for some of the causes of lung cancer we still need to understand. Only in this way can we reduce the incidence rate.

What are the metastasis pathways of lung cancer

First, direct diffusion The tumor near the periphery of the lung can invade the pleura and chest wall. The tumor near the central type or mediastinum can invade the pleura and chest wall. The tumor near the central type or mediastinum can invade other organs. The huge tumor can have central ischemic necrosis and form cancerous cavity. 　　

2. Hematogenous metastasis. It is an advanced manifestation of lung cancer. After the cancer cells return to the left heart with the pulmonary vein, they can be transferred to any part of the body. The common metastatic sites are liver, brain, lung, bone system, adrenal gland, kidney and pancreas. 　　

Third, intrabronchial dissemination. In the case of alveolar cell carcinoma, the cancer cells on the bronchioles and alveolar walls are easy to fall off; the cancer cells can spread to the adjacent lung tissue through the bronchial tube and form new cancer foci.

matters needing attention

In our daily life, if we smoke and drink for a long time, it can cause lung cancer. And if we work in a radioactive environment for a long time, we are prone to suffer from lung cancer. Therefore, in our daily life, we must take measures to prevent lung cancer.
