A cancer survivor is someone who has survived from the time of diagnosis of a tumor to the end of life. As a result of early diagnosis and treatment, there are approximately 12 million cancer survivors in the United States and growing steadily, with roughly 1 in 25 Americans being cancer survivors. Many cancer patients are actively looking for information about how to choose food, how to exercise, how to apply nutritional supplements, how to improve the sensitivity of treatment through nutritional therapy, so that they can recover quickly, reduce the risk of tumor recurrence, and thus improve the quality of life.
