Can you grow your own cancer fighting foods? Before you read any further you need to know that I am not a cancer expert but merely a gardener but from what I read you can grow your own foods which are supposed to help in the fight against cancer. However, I need to caution you with something that happened to an Aunt of mine. She was diagnosed with cancer in her liver and after seeing a few specialists she and her husband were so enthusiastic about how they were going to beat this disease with eating certain foods it was enlightening. It did not work in her case but that does not mean it cannot work in other people and in other circumstances.
