@zazanana, I am happy to welcome you to Mayo Connect. I hope that I can provide some information that might be useful to you as you consider making this important decision. I am a liver/kidney recipient, however, I believe that all type of organ transplant patients can identify with the difficulties involved in making this decision.
Here are some ideas that helped me: I spoke to my family, a few close friends, my pastor, and to doctor(s). I searched for reliable information from major transplant centers. When I was referred to the transplant center, the transplant team was able to provide educational materials and to personalize it to my own specific situation.

I also made it my primary goal to focus on the positive aspects. It is a fact that transplant is a major operation that can involve many complications, however, it can improve your health and quality of life. Knowing what to expect of the lung transplant process, the surgery itself, potential risks and follow-up care are important to consider.

Here are stories that lung transplant recipients for you to read.

I look forward to hearing more from you.
