CBD oil... but i know someone who had cancer, and used both CBD and smoked marijuana. His cancer is gone.
CBD helps some types of cancers, and others not so much.
A person with cancer needs to stop eating all foods which convert to glucose (sugars) in their bodies, including bread, pasta, cereal (all grains), baked goods, any type of sugar, cow's milk. Their best bet is to stop eating all processed foods completely.
Sugar feeds cancer and causes it to grow more readily
