Doctor warns: These signs may reveal lung cancer

Dr. Hossam Mofei warns that persistent cough, blood in phlegm, unexplained weight loss, or pain could indicate lung cancer. The professor of critical care medicine stated that 80% of lung cancer patients are smokers, and passive smokers are also at risk. Early stages of the disease are often asymptomatic, delaying diagnosis and treatment. Mofei recommends regular chest X-rays for smokers, even without symptoms, to enable early detection and improve treatment outcomes.
