HI @silvergirl29, There are different types of lung biopsy procedures. Most go down the throat, which sounds scary, but it's the least risky. Other types use a needle placed through the chest wall. You are obviously put under anesthesia for both. Generally, you may have a little coughing afterward, but recovery is usually fairly easy.

It sounds like you have a good team, and they obviously know your history the best. Here are some thoughts/questions that may help you. I would be curious, if they are able to biopsy the lymph node. If not, are they able to take just a wedge, or because of the location do they need to take the entire lobe? You've already had a reduction in lung capacity, would missing another lobe have an impact on your daily life going forward?
Best of luck to you!
