I don't have the facts you are looking for right now, but I'm so close to being cured I can taste it. And my mother had stage 3 Breast Cancer when I was a sophomore in college and it was a essentially a death sentence(this was back in 2004) but she beat it. Last year she was diagnosed with stage 4 cancer that had metastasized to her lungs and bones. She is alive and well and much healthier than she was in the past.
There is a light at the end of the tunnel, and when you beat this you will have built your discipline and other character traits and you will be a stronger person. I'm starting to feel like these last 2 years of misery were in fact a blessing from God, I would not be the man I am today if it were not for them.
