I have a classmate&;s mother. When she was over 60 years old, she coughed a little at first, but she didn&;t take it seriously, but taking many anti-inflammatory drugs didn&;t work. The cough in the back is getting worse and worse, and even coughing up blood. I went to the hospital for examination, made an X-ray, and found a small shadow on my lung. The doctor said it might be lung cancer, so I suggested going to a big hospital. My classmate took her mother to the hospital in the provincial capital and made a film. The doctor also said it was lung cancer, saying that she could eat whatever she wanted when she went home! That means there&;s no need to treat it. My classmate still didn&;t believe it, and took her mother to the hospital in Tianjin for examination. As a result, a polyp grew on her lung, which was benign after biopsy and no operation was performed. But why does her mother always cough and cough blood? The doctor said it was a bad cough, which caused bronchiectasis and blood vessel rupture. I hung up for a few days and came back after losing some anti-inflammatory drugs. Up to now, her mother is 84 years old, and she can still run around on a tricycle! That&;s why some people say that the equipment is the same, but you still have to go to a big hospital to see a doctor, because the doctors in big hospitals are experienced.
