Cancer is also caused by unhealthy lifestyle. Not just food. Our body needs food to function and survive. If you want a healthy body, you need to adopt a healthy and disciplined lifestyle. Means exercising few times a week, eating on time (regardless of whether you’re hungry or not), etc. Eating only when you’re hungry is actually a bad habit. You end up eating more and by the time you’re hungry you’ll tend to give in to cravings. Deliberate fasting every now and then is good for detoxing the body. This kind of fasting has proper diet plans which is designed specially for detox and health purpose. Skipping meal is not fasting, that is a wrong concept. And it’s also not a good health habit.

Don't bother. You are only gonna make the people here dumber with your explanations.
