A healthy diet low in cholesterol may reduce the risk of breast cancer

A product of cholesterol can increase the number of deaths and causes of breast cancer , according to researchers .

The results of these studies raise hopes the use of drugs that lower cholesterol called statins can prevent cancer .

The study , published in the journal Science , explains how obesity becomes the biggest risk factor of this disease .

Even so , cancer charities said it was too early to recommend that women taking statins in an attempt to prevent breast cancer .

Obesity is associated with many types of cancer including breast , bowel and uterus .

Fat in obese people can pump various types of hormones , such as estrogen , which can trigger cancer growth .
A healthy diet

A team from Duke University Medical Center , in the U.S. , showed that cholesterol has a similar effect .

Cholesterol is broken down by the body into 27HC , which can mimic estrogen and produce the same effect as the hormones in some tissues .

Experiments conducted on mice showed that a high-fat diet can increase blood levels of 27HC and trigger tumor g 30 % greater than in normal rats on a diet .

The tumor is likely to spread . And in human breast cancer tissue grown in the lab more quickly when added 27HC .

One researcher Professor Donald McDonnell said : " Many studies have shown a link between obesity and breast cancer , and in particular high cholesterol is associated with breast cancer risk , but there is no mechanism that can be identified .

" What we have discovered is the molecular us - not koleterol itself, but an excess of cholesterol metabolism - called 27HC which mimics the hormone estrogen and can lead to breast cancer . "

The researchers said their findings raise hopes that by reducing cholesterol may reduce the risk of breast cancer growth .

Statins have been used by millions of people to reduce the risk of heart disease . However , penelitisn it shows statins may reduce the risk of breast cancer .

A healthy diet can be done to reduce the level of cholesterol in the blood .
