What are the causes of lung cancer

In life, many people like to smoke and drink, which will affect the health of the lungs. Usually, everyone needs to pay attention to lung cancer. When this disease occurs, it will cause abdominal pain in patients, and it will also cause great impact on patients, leading to difficulty breathing. Usually, everyone needs to pay attention to the causes of lung cancer. What factors lead to lung cancer?

1. Early stage non-small cell lung cancer:

Surgery should be the first choice for early stage non-small cell lung cancer. However, for patients with cardiopulmonary or medical diseases who cannot undergo surgery, radiotherapy is a treatment method with low toxicity and reliable efficacy. Some patients are cured by radiotherapy alone. The use of stereotactic radiotherapy or conformal intensity modulated radiotherapy will further improve the efficacy and significantly reduce radiation damage to normal tissues.

2. Postoperative radiotherapy:

For lung cancer patients with postoperative pathological confirmation of residual tumor, positive resection margin and mediastinal lymph node metastasis, postoperative radiotherapy can significantly reduce the local recurrence rate of tumor and improve the survival rate and quality of life.

3. Locally advanced non-small cell lung cancer:

Inoperable locally advanced non-small cell lung cancer should be treated with a combination of chemotherapy and radiotherapy. Recent foreign reports have shown that concurrent chemoradiotherapy is more effective than sequential chemoradiotherapy for patients with locally advanced non-small cell lung cancer. It has now become the standard treatment for patients with this stage of lung cancer in some European and American countries.

4. Advanced non-small cell lung cancer

Chemotherapy should be the main treatment, and radiotherapy should only be used as a palliative treatment method. Radiotherapy has an analgesic effect of more than 80% on bone metastasis and can effectively prevent the occurrence of paralysis caused by spinal metastasis. Whole brain irradiation and stereotactic radiotherapy for brain metastasis can have a good effect of reducing symptoms and improving the quality of life. Radiotherapy can also significantly relieve symptoms such as cough, dyspnea, and superior vena cava syndrome caused by tumors.

The occurrence of lung cancer is also related to bacterial infection. Once this disease occurs, it will cause tissue necrosis. Everyone needs to pay attention to tumors, and pay attention to conditioning methods, avoid chemical stimulation, stay away from ionizing radiation, and in daily life, pay attention to avoid fungal infections. At ordinary times, everyone needs to pay attention to lung health care methods to avoid causing more harm, and usually pay attention to get more rest.
