An increase in breast cancer cases have risen steadily in recent years. Even in Indonesia, breast cancer is already shifting the dominance of cervical cancer. Women entered in the group most at risk from catching the disease than men. However, scientists say, the risk of breast cancer can actually pressed nearly 30 percent by doing exercise routine. Researchers noted, gaining weight, which can ruin an excess benefit from exercise.
"Our study suggests that physical activity can reduce the risk of mild breast cancer," said research leader, Lauren McCullough, of the University of North Carolina Gillings School of Global Public Health in Chapel Hill, NC.
"Most importantly, we found a decreased risk of breast cancer for women who are involved in the exercise after menopause. This is very encouraging considering that in old age is early breast cancer development. "he said. These findings are published online on June 25, 2012.
In his research, McCullough and colleagues collected data on more than 1,500 women with breast cancer and 1,500 women without breast cancer. All the women have been taking part in the Long Island Breast Cancer Study Project.
Researchers found that women who exercised before or after menopause have decreased breast cancer risk. Women who exercised 10 to 19 hours a week benefit the greatest cancer risk reduction-about 30 per cent.
McCullough said that he could not explain how exercise can suppress the risk of breast cancer. But to be sure, by maintaining normal weight remain has been associated with decreased risk of breast cancer.
"It is estimated that the reduction of body fat reduces exposure to the circulation of hormones, growth hormones (growth factor) and pro-inflammatory markers, all of which have proven to be associated with breast cancer risk," he said.
"Other mechanisms including an enhanced immune response, antioxidants and DNA repair capacity," he added.
An expert believes that in order to reduce the risk of breast cancer, one must have a healthy lifestyle as a whole.
"More and more proof that one woman can do to reduce the risk of breast cancer and the other is by changing their lifestyle," says Dr. Stephanie Bernik, Chief of surgical oncology at Lenox Hill Hospital, in New York City.
According to the women who routinely Bernik, exercising more likely live a healthy lifestyle-tend to pay attention to what is in the eating, don't smoke and don't consume alcohol.
"It's hard to say that in order to lower the risk of cancer, you only need to exercise. If you live a healthy lifestyle, the risk for cancer may be lowered, "lid.
