運動量大 降低乳癌風險Large amount of exercise reduce the risk of breast cancer

運動量大 降低乳癌風險 健美操等運動量大的活動，可提高身體機能，增強身體免疫力，降低患乳癌的風險。 【新華網】美國的一項新研究顯示，體重正常的停經婦女多進行大運動量鍛鍊，可使其患乳癌的風險降低約30%。 這是美國國家癌症研究所的科研人員在對3萬多名停經婦女進行11年跟蹤研究後得出的結論。研究人員說，大運動量鍛鍊既包括快走、打網球、跳健美操、在野外騎自行車和跳舞等體育活動，也包括擦洗地板和擦窗戶等家務活。 研究者撰文說，大運動量鍛鍊僅對體重正常的婦女產生效果，而對那些體重超重的婦女效果不明顯，因為體重超重增加婦女罹患乳癌的風險。此外，「非劇烈運動」對預防乳癌沒有效果，這些「非劇烈運動」包括使用吸塵器、洗衣服、散步、遠足、慢跑和打保齡球等。 研究人員認為，大運動量鍛鍊能提高人的身體機能，增強身體免疫力，減少致癌因素並避免慢性炎症，從而降低了患乳癌的風險。這項研究成果刊登在最新一期美國「乳腺癌研究」雜誌上。 偏頭痛女性 乳癌機率小 此外，美國研究人員說，有偏頭痛病史的女性患乳癌機率比沒有偏頭痛者低30％左右，這可能與這些女性體內的荷爾蒙水平有關。 這一研究由美國西雅圖佛雷德‧哈欽森癌症研究中心教授克里斯托福‧李主導。這一研究首次將偏頭痛和乳癌患病率聯繫起來。 研究人員研究了西雅圖地區3412名已停經女性，其中1938人曾被診斷出患有乳癌，其餘1474人則沒有乳癌病史。這些女性都回答了有關自己是否有偏頭痛病史的問題。 李說：「我們發現，總體來說，有偏頭痛病史的女性比沒有這項病史的女性患乳癌的機率低30％。」 儘管研究人員沒有找到為何患偏頭痛女性不易得乳癌的原因，但指出這些女性體內的荷爾蒙水平可能是關鍵因素。 因為一般情況下，乳癌由女性體內的荷爾蒙誘發，例如雌激素和黃體酮等。而患偏頭痛的女性體內荷爾蒙水平一般較低。 這項研究結果發表在最新一期「癌症流行病學、生物標誌和預防」雜誌上。根據美國癌症學會統計，全球每年約有46萬5000名女性死於乳癌。 2008-11-20 Large amount of exercise reduce the risk of breast cancer Large amount of exercise such as aerobics, to improve bodily functions and strengthen the body immune system and reduce the risk of breast cancer. 【Xinhuanet the United States, a new study shows that normal weight-menopausal women for more hard training, so that it can reduce the risk of breast cancer by about 30%. This is the U.S. National Cancer Institute researchers in more than 30,000 post-menopausal women 11 years of follow-up study concluded. The researchers said that the major training exercise includes brisk walking, tennis, dance aerobics, cycling and field sports activities such as dance, but also scrubbed the floor and Cachuang Hu, and other household chores. Researchers said the author, the training exercise only of normal weight women have an effect, and those who were overweight women was not obvious effect, because overweight women increased the risk of breast cancer. In addition, the "non-violent movement" was not effective in preventing breast cancer, these "non-violent movement," including the use of vacuum cleaners, washing clothes, walking, hiking, jogging and bowling and so on. The researchers believe that the large amount of exercise training can improve the functional ability of people to enhance the body immunity, reduce cancer-causing factors and to avoid chronic inflammation, thus reducing the risk of breast cancer. The study results published in the latest issue of the United States, "Breast Cancer Research" magazine. Migraine small chance of breast cancer in women In addition, U.S. researchers said there is a history of migraine women suffering from breast cancer than those without migraine chances are low at around 30%, which may be related to those in the body of the female hormone level. The study by the United States ‧ Seattle Fred Hutchinson Cancer Research Center, Professor Christopher Lee ‧ lead. The study will be the first time, migraine and linked to the prevalence of breast cancer. The researchers studied the Seattle area 3412, it has been suspended by the women, of which 1938 people have been diagnosed with breast cancer, the rest of 1474 were no history of breast cancer. These women have answered the question about whether they have a history of migraine. Lee said: "We found that overall, there is a history of migraine than those without the history of women's chances of women suffering from breast cancer by 30%." Although the researchers did not find why women suffer from migraine difficult to get breast cancer, but pointed out that these women are the body's hormone levels may be the key factor. Because under normal circumstances, the body of the female breast cancer by hormone-induced, such as estrogen and progesterone, and so on. The women suffer from migraine generally low level of hormones in the body. The study results were published in the latest issue of "Cancer Epidemiology, Biomarkers and Prevention" magazine. According to the American Cancer Society statistics, every year about 465,000 women died of breast cancer. 2008-11-20 | View more information, see the World Journal reported that e-ePaper
