Questo documento della European Cancer Conference ha preso in esame i dati raccolti da 70,000 donneo visitate dal 1978 al 1985. Fino al 2004 è stato diagnosticato un tumore della mammella nel 4% della popolazione esaminata.
Nelle donne che assumevano alcol (più di due drink al giorno sia vino che birra o superalcolici) mostravano un aumento del rischio di tumore, fino al 30% in caso di assunzione di alcolici in quantità elevata.
All Alcoholic Beverages Increase Breast Cancer Risk
Breast cancer risk rises with increasing alcohol intake -- regardless of beverage type -- researchers reported Thursday at the European Cancer Conference.
Some 70,000 women provided information about their alcohol intake during health visits from 1978 through 1985. Through 2004, breast cancer was diagnosed in about 4% of them.
Compared with women who had reported consuming less than one alcoholic drink a day, those who consumed one to two drinks daily had a 10% increased risk for breast cancer, and those who drank three or more daily had a 30% increased risk. The trend remained significant in analyses stratified by intake of wine, beer, or liquor.
The researchers conclude: "These data show the relation of alcohol intake to increased [breast cancer] risk is independent of beverage choice, indicating that ethyl alcohol is the likely culprit."
