A doctor's office mentioned getting a biopsy (of something on pancreas) by putting tube down my trachea, while doing an ultrasound. That didn't sound good to me. Asked if could be done another way, so a doctor who does it says it could be done with needle but may be more difficult cause so small. (She didn't mention waiting till the tumor or whatever is bigger). That will be my next question to them. But didn't think have a tube put down my trachea is a good idea. Anyone with Copd experience this?
