Check out an extract of wild cumin seed called "Black Seed Oil". Buy the stuff from Egypt or Saudi because that stuff is wildcrafted. The crapola from India or China is cultivated and does not pack the same punch. The oil is peer reviewed and shrinks tumors. It is strong stuff. One tablespoon per day is plenty.
Eat freshly. Dont buy boxes or cans. Make at least one meal per day of fresh and uncooked plant food.
Get some exercise as you are able. Stretch your capabilities. Make sure the air quality in your home and surroundings is good.
Dont let bummer ideas control your life. If your current doc doesnt know what to do or wants to repeat now that you have been rinsed, so to speak, find a doctor with new ideas.
Look around for stories of folks who are alive despite and follow their example as you are able.
Stick around. Get comfy. Dig in for a spell.
