9 年前，隸屬世界衛(wèi)生組織（World Health Organization）的一組委員會說，一項對動物和人的研究顯示，輪班工作制與乳腺癌可能有關聯(lián)。但是最新的科學研究是否與該說法一致？長期上夜班的女性患乳腺癌的幾率是否會增加？請聽 報道。

More than half a million British women, about 5% of the female labour force, work at night. Each year, more than 50,000 women are diagnosed with breast cancer in the UK, and around 11,000 die from the disease.

A number of studies have concluded that working at night is probably linked with breast cancer, with the risk increasing the longer the night shifts continue. In 2007, the World Health Organisation Committee suggested hormone production might be affected by disruption of the body clock.

However, the latest study which reviewed data from 1.4 million women and included ten different studies and several countries, concluded that there was no link. Its lead author Dr Ruth Travis of Oxford University said the incidents of breast cancer was the same whether a woman had never worked at night or completed 20 or more years of night shifts.
