Exercise May Help Prevent Breast Cancer

Exercise can help breast cancer and help those who that is, two new studies show.

The first study on interviews with 15,000 women is based, shows that women who get more than six hours of intense exercise a week, have no family history of breast cancer and may become ill as 23 percent less likely that women s practice " all times. The second study shows a 12-week program group mood and physical function in women with increased breast cancer risk of early exercise.

The exercise work, the researchers did not promise to prevent breast cancer, breast cancer or the blame on a lack of movement. Many factors influence the risk of cancer. But they point out benefits of exercise were published in the protection against cancer in women of all ages.

"We have found that exercise likely offers protection against breast cancer regardless of the stage of a woman in life," researcher Brian Sprague, University of Wisconsin Paul P. Carbone Comprehensive Cancer Center, said in an American Association for Cancer Research (AACR) press release. Should "The message to women that it never start too late for the training," says Sprague.

The study by Sprague, Amy Trentham-Dietz seems, assistant professor, Ph.D., also of the Carbone Cancer Center, and others, in Cancer Epidemiology Biomarkers & Prevention.

For the study, researchers surveyed more than 15,000 women in Massachusetts, New Hampshire, Wisconsin, and by phone. The respondents included 6391 patients without breast cancer and 7630 women with breast cancer. The women were 20 to 69 years, with somewhere between 49 and women in their 50s, and the split in the 60s.

Most had no family history of breast cancer, women with breast cancer, including myself. While family history increases the risk of breast cancer, most patients have no family history of disease.

In the telephone conversation of 40 minutes for women, whether they participated in the following activities at a particular time in her life since age 14: jogging / running, cycling, walking, aerobics / aerobics / dance, sports, snow shoeing, swimming / walking for exercise or other strenuous activities, individual or team.

Most women who develop breast cancer if they had reported three hours a week of intensive training at a certain point in 14 years. But 461 women without breast cancer and 332 patients with breast cancer, said they had exercised vigorously for more than six hours per week on a specific point in 14 years - as a rule, and if they were in their youth in the early '20s.

Women who are more than six hours of intense physical activity per week were reported leisure show 23 percent less likely to breast cancer, compared with sedentary women in the study. Exercise seemed to benefit women, regardless of age. But the advantages are only those who do not know, family history of breast cancer.

The results after adjustment for other risk factors for breast cancer instead.

The study does not prove that exercise prevents breast cancer alone, or show how they reduce the risk of breast cancer movement.

Can help the effects of exercise on hormones and weight suggest the researchers. They realize they do not know if women remembered exactly who their training habits.

The second study comes from researchers such as Nanette Mutrie, Ph.D., professor of exercise and sport psychology at the University of Strathclyde in Glasgow, Scotland. They studied 203 women with early breast cancer who have 51 years on average and not.

The patient underwent surgery for breast cancer prevent (lumpectomy or mastectomy) and has always had chemotherapy and / or radiotherapy to her cancer is back.
First, the women completed questionnaires about their mood and quality of life. They also took a walk test is 12 minutes and had their shoulder mobility checked.

Then divides the team into two groups of women Mutrie. One group participated in a 12-week exercise group. The other group was not asked to make.

Women in the exercise group met twice per week for 45 minutes of exercise. They were also asked to work once a week on their own four walls.

To set for the first six weeks of their 12-week program, the training group after school on topics such as goals and discuss together the health benefits of exercise.
Both groups of women repeated the psychological and physical tests at the end of the program after 12 weeks and six months.

Those in the exercise group improved their findings on physical examinations, and also reported to be in a better mood and more dignified with breast cancer. The benefits usually during the 6 months follow-up instead.

It is not clear how the services are maintained through the exercise or the social group. However, the researchers say doctors "should encourage activity for patients with cancer," and that future studies should exercise at home programs can be more convenient for some patients.

The study is published in BMJ Online First. BMJ, formerly known under the name of the British Medical Journal.
