Lung cancer is one of the most common and serious forms of cancer worldwide. It develops when abnormal cells in the lungs grow uncontrollably and form a tumor. Smoking is the leading risk factor, but non-smokers can also develop lung cancer due to factors such as air pollution, occupational exposure, and genetic predisposition.
Early diagnosis significantly improves treatment outcomes. Radiation therapy plays a vital role in managing lung cancer, either as a primary treatment, in combination with chemotherapy, after surgery, or for symptom relief in advanced stages. Modern radiation techniques allow precise targeting of the tumor while minimizing exposure to the heart, healthy lung tissue, and spinal cord.
Treatment planning begins with detailed imaging such as CT scan, PET-CT, or MRI to determine the stage and spread of the disease. Depending on the type and stage, treatment may include surgery, radiation therapy, chemotherapy, targeted therapy, or immunotherapy.
Advanced radiation techniques such as IMRT, IGRT, and stereotactic radiation therapy help deliver high-precision doses to the tumor while reducing damage to nearby healthy tissues. In selected early-stage cases, stereotactic body radiation therapy (SBRT) may provide excellent tumor control with fewer treatment sessions.
With timely diagnosis and comprehensive multidisciplinary care, lung cancer treatment can significantly improve survival, relieve symptoms, and enhance overall quality of life.
