Lung Cancer Diagnosis and Treatment

Lung cancer kills more people worldwide than any other cancer, largely because most cases are caught only after the disease has spread beyond the lung. Clinicians and researchers work to change that through low-dose CT screening programs capable of detecting small nodules years before symptoms appear, while imaging tools like positron emission tomography help determine how far a tumor has advanced—information that drives every subsequent treatment decision. Once staged, patients may receive surgery, chemotherapy, radiotherapy, or newer targeted approaches such as stereotactic body radiation therapy, often in combination as adjuvant strategies aimed at eliminating residual disease. Active questions center on which screening populations benefit most, how to distinguish harmless nodules from early malignancies without unnecessary intervention, and how to sequence or personalize treatments for the genetically diverse subtypes of non-small cell lung cancer.
