Washington, Feb 25 (ANI): Drinking alcohol - even low amounts - raises the risk of certain cancers in women, according to a new study.
As per a report in the February 24 online issue of the Journal of the National Cancer Institute, low to moderate alcohol consumption among women is associated with a statistically significant increase in cancer risk and may account for nearly 13 percent of the cancers of the breast, liver, rectum, and upper aero-digestive tract combined.
To reach the conclusion, Naomi Allen, D.Phil., of the University of Oxford, U.K., and colleagues examined the association of alcohol consumption and cancer incidence in the Million Women Study, which included 1,280,296 middle-aged women in the United Kingdom.
Participants were recruited to the study between 1996 and 2001. Researchers identified cancer cases through the National Health Service Central Registries.
Women in the study who drank alcohol consumed, on average, one drink per day. Very few drank three or more drinks per day. With an average follow-up time of more than 7 years, 68,775 women were diagnosed with cancer.
The risk of any type of cancer increased with increasing alcohol consumption, as did the risk of some specific types of cancer, including cancer of the breast, rectum, and liver. Women who also smoked had an increased risk of cancers of the oral cavity and pharynx, esophagus, and larynx.
The type of alcohol consumed - wine versus spirits or other types - did not alter the association between alcohol consumption and cancer risk.
Each additional alcoholic drink regularly consumed per day was associated with 11 additional breast cancers per 1000 women up to age 75; one additional cancer of the oral cavity and pharynx; one additional cancer of the rectum; and an increase of 0.7 each for esophageal, laryngeal, and liver cancers.
"Although the magnitude of the excess absolute risk associated with one additional drink per day may appear small for some cancer sites, the high prevalence of moderate alcohol drinking among women in many populations means that the proportion of cancers attributable to alcohol is an important public health issue," the authors write.
