最新研究表明 經常上夜班不會增加乳腺癌風險

British scientists have recently found that working night shifts is unlikely to increase the risk of breast cancer, clarifying a previous study on the effect of night shifts on women.

英國科學家最近發現，夜班工作不會增加乳腺癌的風險，澄清了之前關於夜班對女性影響的研究。

The new research, funded by the British Health and Safety Executive (HSE), Cancer Research U.K. and the U.K. Medical Research Council, was published in the Journal of the National Cancer Institute last Thursday.

這項新研究由英國衛生與安全執行局、英國癌症研究所和英國醫學研究委員會資助，於上週四在國家癌症研究所期刊上發表。

It followed 1.4 million women in ten studies and analyzed data from studies in the United States, China, Sweden and the Netherlands.

這10項研究共涉及140萬名女性，並分析了來自美國、中國、瑞典和荷蘭的研究數據。

"We found that women who had worked night shifts, including long-term night shifts, were not more likely to develop breast cancer," said Ruth Travis, lead author and cancer scientist at the Cancer Epidemiology Unit at the University of Oxford.

該研究的首席作者、牛津大學癌症流行病學小組的癌症科學家魯斯·特拉維斯表示：“我們發現，上夜班或長期上夜班的女性，並不會因此增加乳腺癌風險。”

Comparing women with and without night shift work experiences, the new study founded that night shifts has "little or no effect on breast cancer incidence in women," said Professor Andrew Curran, chief scientific adviser for the HSE.

健康與安全執行局首席科學顧問安德魯·柯倫教授表示：“通過比較有和沒有夜班工作經驗的女性，這項新的研究發現，夜班對“女性乳腺癌發病率幾乎沒有或沒有影響”。

However Curran also warned that there are a number of other known risks with shift work that harm people's health.

不過柯倫教授警告稱，倒班工作還有一些其他已知的風險會損害人們的健康。

A study by the International Agency for Research on Cancer in 2007 said that shift work is a probable cause of cancer, including breast cancer, as it disrupts an individual's "body clock."

國際癌症研究機構在2007年的一項研究表明，倒班工作是導致癌症（包括乳腺癌）的可能原因，因爲它破壞了個人的“生物鐘”。
