I would suspect bodily stressors like fasting reduce the chances of cancers taking hold because those cells are usually less resilient than normal cells (like the principles of chemotherapy). Having abundant food I would suspect is what gives most cancers a comfortable body to develop in. Also, modern proliferation of toxic chemicals. Furthermore, people living longer are inevitably going to go by either cardiovascular issues/stroke, pneumonia, or cancer.
