The way to prevent the spread of cancer cells in lung cancer generally requires local treatment (surgery and radiation therapy) to reduce the size of the cancerous tissue or to remove it, chemotherapy to kill cancer cells in other potential parts of the body, and molecularly targeted therapy, which is a combination of molecularly targeted drugs that specifically select the cancer-causing sites where they can act to cause specific death of the tumor cells. These modalities are used singly or in combination to inhibit the spread and growth of cancer cells. Traditional Chinese medicine can only play an auxiliary role in the treatment, but cannot completely control the growth and spread of cancer cells. When lung cancer occurs, it is recommended to go to the hospital for reasonable treatment under the guidance of doctors.
