I wish it was more, much more. I understand the struggles, all too well.
As I am of the belief that 'let your food be your medicine and your medicine be your food' (or however the saying goes)......look into cancer fighting foods. Not as a replacement for conventional medicine, but as an extra boost. Kale, turmeric (best with pepper), raw garlic, dark green leafy veggies (spinach, raw if possible), blueberries, pomegranates, wild salmon & other fatty fish, and the list goes on.
Also, your mental & spiritual & physical being helps the body fight the toxins as well. Lay your burdens at His feet, don't worry about what may or may not happen, but laugh, get some exercise & fresh air. Surround yourself with positives. Many think it's a bunch of bunk, but it's also well known the power of the mind to do extraordinary things. Life is 10% of what happens to you and 90% of how you respond (attitude).
There is also what's called the Budwig protocol diet, that includes quark or cottage cheese and flax oil. In fact there are multitudes of information of different approaches to fighting cancer, but trying to find that info now is like trying to find info on DC corruption.
Well, there's alot more I could say, but ultimately you do what you think is best for you and may God bless you abundantly, Amen
