Weight loss and exercise reduce the risk for breast cancer by altering causative estrogen levels
The obese postmenopausal women are found to have higher risk for breast cancer by their mechanism on estrogen release. The obese women’s fat tissues behave like an endocrine gland which in turn release high quantity of estrogen, which encourages the changes of breast cancer and the new study revealed that reducing the body weight moderately reduced the chances of having breast cancer.
The study found two, weight loss and exercise helps in reducing the risk of developing breast cancer and however, the exercise seems to have no remarkable impacts on the circulating hormones.
Losing more weight shows reduction of the chances of developing cancer by reducing the hormone estrogen which contributes to breast cancer.
There are as many as risk factors so far described for enhancing the chances for breast cancer and the past studies so far conducted linked the obesity with breast cancer. But, this is the first study that illustrated weight loss reduces the risk of developing breast cancer.
“This shows it’s never too late to make lifestyle changes to reduce your risk for breast cancer,” said co-author Dr. Anne McTiernan from Fred Hutchison Cancer Center.
The study involved 439 postmenopausal over weight women and divided them in to four groups. one group was put on intensive weight loss, the another one on intensive exercise only, The third group had exercise and diet help. The fourth group were advised not to change their diet or exercise.
After a year, the authors suggested the exercise may help lower breast cancer risk by some means other than lowering estrogen levels, diet and exercise in combinations found highly scored upto 11.9% which could in turn reduce the circulation of estrogen which is the driver for breast cancer.
