Lung Cancer Diagnosis and Treatment

Lung cancer remains the leading cause of cancer death worldwide, largely because most cases are caught only after the disease has already spread, making early and accurate diagnosis a central challenge. Researchers work across imaging techniques such as low-dose CT screening and positron emission tomography to detect tumors at earlier stages, while refining how those tumors are classified and staged to guide treatment decisions. On the treatment side, surgery, chemotherapy, radiotherapy, and newer approaches like stereotactic body radiation therapy are often combined in carefully sequenced regimens, with ongoing investigation into which adjuvant therapies best reduce the risk of recurrence after initial treatment. Key open questions include how to distinguish truly dangerous pulmonary nodules from benign ones found incidentally during screening, and how to personalize treatment for the molecularly diverse subtypes of non-small cell lung cancer.
