Breast Cancer Hormone May Be Lowered by Dieting, Exercise, Study Finds
It has long been understood that the link between shedding excess pounds and general weight loss is strong, but a new study has examined the connection between weight loss and breast cancer hormones, and found another plus point for dieting when it comes to preventing the disease.
Although researchers stopped short from claiming that weight loss will halt the disease, they did acknowledge that the findings provide more options for women who need to mitigate their breast cancer risk. In a news release about the study, Dr. Anne McTiernan, director of the Prevention Center at the Fred Hutchinson Cancer Research Center, explained:
“Weight loss represents an additional option for long-term breast cancer risk reduction without significant or bothersome side effects.”
“The amount of weight lost was key to changes in hormone levels. The biggest effect was through diet plus exercise; exercise by itself didn’t produce much of a change in weight or estrogen.”
The study involved 439 overweight-to-obese women between the ages of 50 and 75, with an average age of 58. The women were separated into four groups: those who exercised only, those who dieted only, those who did both, and those who did neither. The findings were published in the online edition of May 21st’s Journal of Clinical Oncology.
