Lung cancer treatment typically involves a combination of methods, including surgery, radiation therapy, and chemotherapy. The choice of treatment depends on the type and stage of cancer, as well as the patient's overall health. Surgery aims to remove the tumor, while radiation and chemotherapy target cancer cells to shrink tumors or prevent their spread. In some cases, targeted therapies and immunotherapy may also be used. Targeted therapies focus on specific genetic changes in cancer cells, while immunotherapy helps the body's immune system recognize and fight the cancer. Each treatment plan is personalized to improve outcomes for patients.
