Lung cancer treatment is individually planned, depending on various factors such as the patient's general health, the stage of the disease, and the histological type of the cancer. In different stages of the disease, various treatment combinations and individualized approaches are applied. In this process, the selection of a fully equipped healthcare institution and a team of specialist physicians is of great importance. Following lung cancer surgery, adjuvant therapy may be administered to eliminate a small number of cancer cells that may remain, even if not visible to the naked eye. This treatment is meticulously planned considering the patient's pathology reports, age, and general health status. Adjuvant treatment options after surgery may include chemotherapy, radiotherapy, or a combination of both. In some early-stage patients, post-operative adjuvant therapy may not be required.
