If I had lung cancer as you describe I would not be looking to see if a herb can be found. Herbs help cancer but in this case Thunder God is only going to help, not stop your cancer. You have to do something that will be potent and will kill it.
It depends on where you are. And the size or placement of the tumor. Treatments often cause inflammation to the tumor site because it gets 'mad' when you try to kill it; and the body reacts with inflammation. You don't want to do something blindly and cause yourself difficulty in breathing. IPT is a good solution to bring down the size of the tumor if that is going to be a problem. I would then consider looking into Hemp oil but that can be difficult to get depending on where you live. Or I would look into BX Antitoxin and you can get into that program from anywhere in the world. Check out Rick Simpson on google for hemp oil info and your state if in the US. Check out jesichashope.org hit the bxantitoxin button for info on the BX Antitioxin.
If you don't want to bring your cost of living down to zero you will have to do something, and you still have a chance to beat it.
