When it comes to treating lung cancer, many patients consider surgery first. However, surgery is not suitable for all patients, and it is not possible to completely remove the lung cancer “cells”. Many patients waver and hesitate under different recommendations from different specialized doctors, thus missing the best treatment time. Of course, there are also many patients who choose radiotherapy to treat lung cancer, so what is the effect of radiotherapy? This is the most important question for lung cancer patients, and we will explain it to you in detail. First of all, it should be stated that there are different types of lung cancer, and different treatments are needed according to different classifications. There are small cell lung cancer and non-small cell lung cancer. Since the cancer cells of small cell lung cancer are sensitive to chemotherapy, 3-4 cycles of chemotherapy are usually given first, followed by radiotherapy, in order to achieve the best treatment effect. For patients with non-small cell lung cancer, surgery is also generally used as the preferred treatment. However, clinical studies have confirmed that precise radiotherapy has been able to obtain the same or better treatment results than surgical treatment. Of course, it is undeniable that the effectiveness of radiotherapy varies from person to person. However, nowadays, radiotherapy techniques have been successfully developed into precision radiotherapy represented by stereotactic radiotherapy, which can completely kill cancer cells while ensuring the normal function of organs to the maximum extent. Even the smaller side effects usually disappear slowly at the end of the radiotherapy cycle. Currently, 64% of lung cancer patients who cannot undergo radical surgery require immediate radiotherapy, 30% of patients require radiotherapy within 10 months, and only 6% of patients do not require radiotherapy. Therefore, it is important for lung cancer patients to consider the most appropriate treatment for themselves as early as possible before receiving treatment. Currently, radiotherapy alone or a combination of surgery and chemotherapy are operable options. However, the plan must be personalized and designated by a professional oncology radiotherapist according to the patient’s specific situation. If you decide to receive radiotherapy, it is important to note that you must arrange a proper interval after surgery or chemotherapy, and wait for your body to have a certain recovery before administering radiotherapy to achieve a better treatment effect.
