Introduction to the Cancer Prevention Diet

Cancer refers to a large number of diseases categorized by unregulated replication of cells.

Please note, the following contents are limited to information about diet and to a discussion of cancer prevention—not treatment.

Prevention of cancer in a person who has never had cancer is called “primary” prevention. Information found in this area is focused on primary prevention.

This area includes a discussion of studies that have assessed whether certain dietary ingredients may be beneficial in connection with the reduction of risk of developing cancer.

Please note, this information is provided solely to aid consumers in discussing supplements with their healthcare providers. It is not advised nor is this information intended to advocate, promote, or encourage self-use of this information for cancer risk reduction. Some studies suggest an association between high blood or dietary levels of a particular dietary ingredient with a reduced risk of developing cancer. Even if such an association were established, this does not mean that dietary supplements containing large amounts of the dietary ingredient will necessarily have a cancer risk reduction effect.

Prevention of a recurrence in a cancer patient who is in remission is called “secondary” prevention. Whether the information in this area would be helpful to people interested in secondary prevention is, for the most part, unknown. However, of cancer patients who are in complete remission, the information presented here is unlikely to help people who were ever diagnosed with metastatic cancer (also known as stage IV, or advanced, cancer).
