I'm sorry to hear about your diagnosis, but happy that you seem to be keeping such a level head about it. You're right -- cancer can be overcome with natural methods! No question about it. And the more aggressive the cancer, the faster it responds.
I am though a little concerned about your decision to rely purely on glutathione. Yes, it's a powerful antioxidant, but I know of little evidence that it alone will overcome an aggressive cancer. It's the drug mentality that says "take this magic little pill and you'll get better." In the real world, overcoming cancer requires a disciplined, global adherence to a strict, integrated program with strict, integrated program of nutrition and detox.
Please don't try to re-invent the wheel and create a piecemeal program on your own with fragments from here and fragments from there. A few programs have been around for many, many years that have been proven effective time and time again. The best in my opinion are the Gerson program http://www.gerson.org and the Kelley/Gonzalez program http://www.dr-gonzalez.com
