Daily alcohol drinking may increase risk for certain cancers. The Los Angeles Times (4/11, Cevallos) "Booster Shots" blog reports that cancer risk "increases with every extra daily drink," according to a study in the British Medical Journal. The analysis of "364,000 people in eight countries," found that "44% of cancers of the upper aerodigestive tract" in men and 25% in women "might be linked to alcohol"; liver cancer "(33% in men, 18% in women)"; colorectal cancer "(17% in men, 4% in women)"; and about 5% of "breast cancers in women." The American Cancer Society agrees that alcohol "raises the risk of cancer in the mouth, throat, voice box and esophagus." Alcohol may act as a "solvent," to tissue lining, "allowing harmful chemicals through (especially tobacco from smoking)," ACS explained. Alcohol may also raise drinkers' cirrhosis risk by "further damaging liver cells"; and it may "change estrogen levels," increasing breast cancer risk.
