Summary
The effect of diet on cancers of the lung, esophagus, stomach, colon, breast, and cervix is reviewed, based on a series of studies in Japan. Individual and community cancer plans are discussed with special reference to diet. It is our hope to develop an effective and essential community cancer plan with an emphasis on lifestyle improvement. This includes proper management of problems of smoking, drinking, diet, and nutrition and the sound growth of supporting industries for each of these items. It is believed that these are the real bases of an individual cancer plan.
