每日飲酒兩杯 女性乳腺癌患病風險增高50%
Women who drink just two glasses of wine a day are 50 per cent more likely to get breast cancer than those who don’t drink at all, a major study has found.
Even those who indulge in only three or four glasses of wine over an entire week – well within the Government’s recommended limits – are putting themselves at risk.
Researchers also warn that women who drink regularly in their 20s and 30s are far more likely to develop the illness in later life, regardless of whether they subsequently cut back.
The Government recommends that women should drink no more than 14 units a week, which is about seven medium glasses of wine or 14 measures of spirits.
But this study found that even half this amount – seven units a week – could raise the risk of breast cancer by 15 per cent.
And women who drank nearly four units daily – two glasses of wine – increased the likelihood by 50 per cent.
Researchers at Harvard University and Brigham And Women’s Hospital in Boston, Massachusetts, looked at the records of 105,986 women aged 30 to 55 who completed surveys on their current drinking habits and how much they drank when they were younger. Over a period of nearly 30 years they monitored how many of the women developed breast cancer.
Their findings, published in the Journal of the American Medical Association, show that women who drank nearly four units a day were 50 per cent more at risk than teetotallers.據英國《每日郵報》11月2日報道，一項大型研究發現，每日飲用兩杯紅酒的女性與不喝酒的女性相比，罹患乳腺癌的風險要高50%。
甚至那些超過一週只飲用三到四杯紅酒(在政府推薦的飲酒量之內)的女性也處於患病危險之中。
研究人員還警告說女性若在20歲和30歲時經常喝酒，不管飲酒量在後來有沒有減少，都有可能增加晚年生活的患病機率。
政府部門建議女性一週的飲酒量不應超過14單位，相等於7中杯的紅酒或14量杯的酒精飲料。
而且日飲酒量近乎4單位的女性——即每日飲用兩杯紅酒，乳腺癌的患病風險會增加到50%。
但是該研究發現即使每週的飲酒量只有7單位也可能會增加15%的乳腺癌患病風險。
美國哈佛大學和布萊根婦女醫院(位於美國馬薩諸塞州波士頓市)的研究人員觀察了105,986名年齡在30—55歲之間的女性目前的飲酒習慣和年輕時的飲酒量記錄。在過去的近30年裏。研究人員監測了有患上乳腺癌的女性數量。
研究結果顯示， 日飲酒量近乎達4單位的女性乳腺癌的患病風險要比不喝酒的女性多50%。該研究結果發表在了《美國醫學協會》上。
