@maymore You are right, we know alot about what causes cancer, but which type of the 11 types of breast cancer? Yes, common sense would dictate to eat well, exercise, remove harmful chemicals from your life. Live a good life, a full life, a joyful, grateful life. And I am not saying it is just about luck. However two people could follow the same regime and have totally different outcomes. This is what I mean when I say we still know so little. So yes, have a positive mindset, do all the things above, but do them for your life NOW, so our time here is fulfilling.
