* Exercise for at least 20 to 30 minutes per day. The book notes that different types of cancers require different levels of exercise to achieve a comparable effect; for instance, colon cancer requires twice as much as breast cancer.

==Cancer as a Metabolic Disease==

This book, "[http://www.amazon.com/Cancer-Metabolic-Disease-Management-Prevention/dp/0470584920 Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer]" by Dr. Thomas Seyfried, is an expensive, technical book by one of the leading researchers in this field. It's recommended if you want to research more deeply into this topic. There is also a smaller and cheaper eBook called "[http://www.ketogenic-diet-resource.com/cancer-diet.html Fight Cancer with a Ketogenic Diet]" that is based on Seyfried's book.
