Reducing the calories we eat can stop breast cancer from spreading. A restricted diet is as effective as hormone therapy in blocking cancer growth, especially in the most aggressive cases.
This vital insight could mean that cancer patients will not need to be given hormonal therapy to stop cancers metastasizing (spreading) and steroids to counteract the worst side effects of chemotherapy.
Women given steroids often gain an average of 10 pounds in weight in the first year, and studies have shown that sudden weight gain can make chemotherapy less effective.
But new research from Thomas Jefferson University suggests that reducing calories can stop cancers from spreading, and especially triple-negative breast cancer, one of its most aggressive forms.
However, their research has thus far been restricted to laboratory mice, although the researchers are confident that similar results would be seen in human subjects.
