- Question from Pat: Is there research to show that women with hormone-negative cancer should follow a different nutritional plan than women with hormone positive cancer?
- Answers - Cyndi Thomson, Ph.D., R.D. This is a good one. In December's Journal of the National Cancer Institute there was a publication summarizing the results of the Women's Intervention Nutrition Study that included over 2,500 breast cancer survivors. The findings of that study showed that women with estrogen receptor-negative breast cancer had a significant increase in survival from breast cancer. So if you have an ER-negative breast tumor, the current study suggests that you should be on a low-fat diet. This protective benefit of a low-fat diet was not seen in women with ER-positive breast cancer, possibly because we have medications that are highly effective in improving prognoses for estrogen receptor-positive breast cancer. Breast cancer survivors should also be aware of another large diet study among breast cancer survivors, the Women's Healthy Eating and Living Study, which was a plant-based or high vegetable diet—low-fat and high fiber. The results of that study should be out by the end of 2007. That study is out of UC San Diego.
- Melinda Irwin The California Teachers Study also showed that physical activity was more protective against developing breast cancer among ER-negative women.
