Conservative treatment of lung cancer

Conservative treatment of lung cancer

Lung cancer is one of the malignant tumors with the fastest growing incidence and mortality, and is also the biggest threat to population health and life. In the past 50 years, the incidence and mortality of lung cancer have increased significantly in many countries.

Conservative treatments for lung cancer usually include the following two methods:

1. Radiotherapy.

Tumor radiotherapy is the local treatment of tumors using radiation. Radiation includes radiation produced by radioisotopes, α, β, γ, X-rays produced by various X-ray processors or accelerators, and X-rays, electron beams, proton beams, and other particle beams. About 70% of cancer patients need radiotherapy to treat cancer, and about 40% of cancer can be cured by radiotherapy. The role and status of radiotherapy in cancer treatment are becoming increasingly prominent, and it has become one of the main methods for treating malignant tumors.

2. Chemotherapy.

Chemotherapy is the main treatment for lung cancer, and more than 90% of lung cancers require chemotherapy. The efficacy of chemotherapy on small cell lung cancer is relatively positive in the early and late stages, and even about 1% of early small cell lung cancers are cured by chemotherapy. Chemotherapy is also the main method for treating non-small cell lung cancer. The tumor remission rate of chemotherapy for non-small cell lung cancer is 40%~50%. Chemotherapy usually cannot cure non-small cell lung cancer, but can only prolong the patient's survival and improve the quality of life. Chemotherapy is divided into therapeutic chemotherapy and adjuvant chemotherapy.
