"Story:
My buddy has CF and had a double lung transplant 3 years ago, he was doing great! Getting healthier after the recovery and the Docs said he was on the road to a long CF life. The one down side of the transplant is you need to take immunosuppressants so your body doesnt reject the lungs. Which means if you are not careful you can get sick really easily, can get cancer super easily from to much UV exposure, ext.
Any way, his Fiancee goes and cheats on him get warts then gives him warts. And now that has metastasized into cancer. With no immune system to speak of the cancer is now going to run rampant and essentially kill him."
