The first thing you need is resolve.
You must be strong trough all of this.
It's all easy speaking about this with other people and all but when it happens to you it's a whole different matter, and this with regards to most bad things in life.
.. it's all fine until it happens to you.
I can understand.
From what i know, here is what i would suggest to look into.
1) Increased intake of eventually missing minerals and vitamins from the diet.
Orthomolecular dosages are pretty awesome as references.
2)Have a look into Oleander, there is a medicinal called anvirzel but it's way too expensive, i would go for sutherlandia OPC, there is virtually no difference at all in the effects.
Tony Isaac Oleander protocol is fabulous, dig into it and subscribe to the "oleandersoup" mailing list.
Oleander is top tier when it comes to developing immune system, it just needs some time to fully kick in, and you need to gain more time to fully benefit from it.
3) Even if you decide to undergo chemo and radiation, give naturals a go as an additional treatment to decrease side effects and improve cancer killing rate.
As you must be knowing by now, both chemo and radiation do have an effect on cancer but they don't make any difference from healthy or non healthy cells.
4) Research pancreatic enzymes.
It does appear they are able to neutralize the barrier cancer cells create around themselves.. that would help a lot your immunity forces.
Dr. Nicholas Gonzalez and Dr. Linda Isaacs have written pretty much about it, if i'm not wrong there is also a book on this.
You need all the possible bullets in your arsenal.
Be strong, resolve! and never back down, you can beat it I'm sure.
