question: Hi doctor, I have a persistent cough with phlegm, chest pain, exhaustion after a short duration and nodules in the right lung. The x-ray revealed that signs of atelectasis are present. After using three different types of medicine and steroid inhaler, the symptoms are still present. The most recent prescription includes Ciprofloxacin for 10 days. I had antibiotics for two weeks before the recent medications. Am I suffering from lunch cancer?
