Surgeon shares 3 warning signs of lung cancer, says 'Even non-smokers not risk-free'
Dr Tarang Krishna, a cancer surgeon specialising in cancer immunotherapy, has shared three signs of lung cancer. The signs are persistent coughing for two or three weeks, coughing up blood, experiencing chest pain or breathlessness while performing routine activities. "Non-smokers are also not risk-free. Air pollution and passive smoking are the biggest trigger points for lung cancer," he stated.
