I have been taking treatments since January 2010 for renal cell carcinoma that metastazied to stage 4 lung cancer. Most of the nodules on my lung are gone, all but one. I just had a CT scan 2 weeks ago and in the last 2 scans it has not progressed!!! My doctor says I am doing much better than he thought I would. So Yea, and Thank You God for helping me fight this battle! I will beat you Cancer!
