This technology could not come any sooner. I lost my 37 year old wife to metastatic cancer. We were able to arrest the spread and even shrink the primary areas with established treatments but due to the vascularization of the lungs, could not get them disease free and that's what killed her. The thought of having had the chance to replace her lungs and let the biotechnology wipe out the malignant cells everywhere else is a prayer for patients and caregivers alike. Keep up the good fight dear scientists.
