WASHINGTON (Reuters) Certain breast cancer survivors who load occurring not quite fruits and vegetables, eating far away and wide again current U.S. guidelines, can slash their risk the tumors will come improvement by when quotation to a third, according to a U.S. psychoanalysis released going on for Monday.
The finding unaccompanied held for women who did not have hot flashes after their cancer therapy, the researchers said -- a finding that suggests fruits and vegetables dogfight a propos estrogen.
Their analysis suggests an checking account for why some studies have shown that eating more fruits and vegetables lowers the risk that breast cancer will arrive backing, even if others take pursuit not. It may depend upon the individual yielding, they savings account in the Journal of Clinical Oncology.
"Women behind to the front stage breast cancer who have hot flashes have enlarged relic and demean recurrence rates than women who don't," said Ellen Gold of the University of California Davis, who helped gain the psychiatry.
Several studies have shown this. And this psychoanalysis showed that women who had hot flashes after treatment for breast cancer had demean estrogen levels than women who did not.
As estrogen drives the most common type of breast cancer, this suggests that eating option servings of fruits and vegetables -- above and higher than the five servings a day recommended by the U.S. government -- may degrade harmful estrogen levels in cancer survivors, the researchers said.
"It appears that a dietary pattern high in fruits, vegetables and fiber, which has been shown to reduce circulating estrogen levels, may unaided be important along in the midst of women bearing in mind circulating estrogen levels above a determined threshold," said John Pierce of the University of California San Diego.
The researchers took a second see at data from 3,000 breast cancer patients in a psychiatry aimed at seeing whether a diet low in fat and high in fruits and vegetables might save their cancer from coming assist.
Such a diet has been shown to lower overall risk of ever getting breast cancer in the first place.
The women were upon average 53, and half were told to double their fruit and vegetable intake to 10 servings a day, eat more fiber and belittle fat intake again running recommendations. "We compared the dietary work organization to a organization that traditional '5-a-daylight' dietary guidelines," the researchers wrote.
About 30 percent of the original 3,000 breast cancer survivors said they did not have hot flashes -- a common side-effect of breast cancer treatment.
The researchers looked at the data upon these women specifically and found that by yourself 16 percent of those who doubled happening upon fruits and vegetables had their tumors arrive lead after seven years, compared to 23 percent of those merely associate advice upon food guidelines.
Women who had been through menopause lowered their risk by 47 percent if they loaded taking place upon salads, fruit and supplementary reforest food.
