My wife had similar problem more than 20 years ago. But we decided don't do any "official" radio/chemo/... therapy, because we new - it will just prolong life a little. We stuck to orthodox church (visited every week liturgy and received communion) and try this and that. My wife had strong weakness, so it was very hard to go to church, but we did. Then she kept complete fast for more than 20 days - only use Christmas holy water I brought from church - she lost muscles, but feel better. Then she tried Maya Gogulan recommendation - so-so.
And finally we got very simple recipe - 30ml of vodka (40%) + 30ml of nonfiltered cold pressed sunflower oil. Mix, shake 5 min or more, drink (before drink don't eat and don't drink for 2 hours), wait for 20 min and eat what you can (buckwheat is best + some vegetables). And do it with 5 hours interval 3 time a day. 10 days drink - 5 days break - 10 days drink - 5 days break - 10 days drink - 14 days break => full cycle. And continue this cycle for many years. One important thing - sunflower oil should not have any "poisons", better to be organic and should have many linoleic fatty acid, alpha-tocopherol, and phosphates.

One disadvantage of this method - you have to keep diet - mostly buckwheat and vegetables. Avoid fried food. Avoid fat food. Don't use alcohol. Don't have stress (even from hot or cold weather). And don't use any drugs/injections, especially against cancer - it's poison.
My wife still live and we also tested this method with my father - he had intestines cancer, so we forced him to use. And he came back to work. Felt good for 2 years (even cancer was not disappeared - just size decreased). Then he become tired of drinking this mix and keeping diet and decided to make chemo injection. Within 3 month after injection he passed away. So chemo therapy is very poisoned...
10 years ago I also had problem with heart, so couldn't sleep and started to drink 2 times a day. Since that even my heart is not strong I can sleep and work (not only with comp). On that site you can read a lot of positive feedback mails from other people who had different types of cancer even in terminal stage. They even drop pain relievers.
And one most important thing - to live you should have reason. In our case we had 2 children and can't imagine the would be orphans. Also in our world only God gives us live - only He can give us chance if we ask Him not for our pleasure but to serve to other people.
Excuse me for this long post. I wish you spiritual and physical health.
