Dr. Apar Jindal of Max Smart Hospital warns that a cough lasting over three weeks or accompanied by blood-stained sputum requires immediate medical evaluation for lung cancer.
Other potential warning signs for lung cancer include unexplained weight loss, persistent fatigue, chest pain, wheezing, and a hoarse voice, according to the pulmonologist.
Diagnostic advancements now include molecular testing and image-guided biopsies, allowing for personalized treatment options like immunotherapy or targeted therapy for early-stage patients.
