專家們說沒有充足的證據(jù)能證明飲用咖啡會增加患癌癥的風險，從而降低了咖啡致癌的風險級別。過去，有專家曾指出咖啡和膀胱癌之間有所關(guān)聯(lián)，但其實并沒有足夠的證據(jù)來證明咖啡到底是否是“致癌物質(zhì)”。以下是 Adam Brimelow 的報道。
The decision to reclassify coffee was taken after a review of more than a thousand studies carried out by the International Agency for Research on Cancer.
It runs a register of environmental causes of cancer which runs from Group 1, where the evidence is convincing, to Group 4, where there's no risk.
Since 1991, coffee has been in category 2B reflecting a possible link to cancer. Now it's switched to category 3, which means there no conclusive evidence of a cancer risk.
The review concludes very hot beverages probably do cause cancer. Experts have urged people to let their drinks cool down for a few minutes.
