New Delhi, Nov 28 (ANI): Lung cancer is one of the most common cancers in the world. There are two major types of lung cancers, Non Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC). Knowing which type you have is important because it affects your treatment options and your outlook. Surgery, radiation, chemotherapy, targeted treatments and immunotherapy alone or in combination are used to treat lung cancer patients. Use of individual treatment options would be based on the stage of cancer and symptoms. Surgery: Most stage 1 and stage 2 lung cancer patients are treated with surgery to remove the tumor if the patient is very fit. As most of the lung cancer patients are not very fit and suffer from poor lung and heart condition, up to 10% of patients only can undergo curative lung surgery. Radiation: Patients with early lung cancer, but not suitable for surgery (stage 1and 2), or advanced lung cancer (stage 3) are treated with radiation with the intention to cure. Sometimes both radiation and chemotherapy given together. Chemotherapy: For most advanced cancer patient chemotherapy is used to control the tumor growth. Chemotherapy generally has some side effects and is only given to fit patients. In some situations, chemotherapy is used after surgery to improve the cure rate. Targeted therapy: One of the most exciting developments in oncology field, many of these medicines are oral tablets which can be taken at home with minimum supervision. These medicines tend to have fewer side effects as compared to chemotherapy. Immunotherapy: This has recently emerged as a new treatment option. This class of drug seems to have even less side effects. Immune check point inhibitors (PD-L1) targeted drugs have already shown a promising role, and are likely to emerge as main therapy for lung cancers in future. Newer treatment options particularly targeted therapy and immunotherapy have changed the treatment paradigm in lung cancer and hold great promise.
