The main metastatic pathways of lung cancer

The main metastatic pathways of lung cancer are:

The main metastatic pathways of lung cancer generally include lymph node metastasis, blood metastasis and implantation metastasis.

1. Lymphatic metastasis:

Lymphatic metastasis of lung cancer usually occurs earlier and spreads faster. The metastatic pathway usually spreads to the clavicle, mediastinum, axillary and cervical lymph nodes through the hilar lymph nodes and bronchi.

2. Hematogenous metastasis:

Due to the abundant blood flow in the lungs, lung cancer cells can invade the pulmonary veins or enter the pulmonary veins through the pulmonary capillaries, and then spread to organs throughout the body through the left heart, leading to distant metastasis of lung cancer.

3. Implant transfer:

Tumors near the lungs can invade the visceral pleura, and cancer cells can break off and enter the pleural cavity, forming implant metastasis.

Patients should pay attention to maintaining an optimistic attitude, exercising properly, and strengthening nutrition. Patients also need regular checkups, such as chest CT, bone scan, abdominal ultrasound, and routine biochemical indicators, and dynamic observation of the patient's condition, so that early diagnosis and early treatment can effectively prevent recurrence.
