I understand that this forum is not for lung problems. Please forgive me if I use it for my purpose. Please bear with me on this.....

My question are :

1. Does COPD, by any cause - chronic asthma, smoking, chronic bronchitis, auto-immune diseases, emphysema, exposure to toxic enviroment, etc., show on CT scan?

My last scan dated January 2011 shows two scars which might have been caused by the ileocecal T.B.

2. Swimming may be one of the better exercises for the lungs, but normally the pools are heavily treated with chemicals. Does using swimming pools acceptable for patients with COPD?

Thank you so much for your answers.
