European researchers pooled more than 100 studies and found up to one drink a day raised women's breast cancer risk by 4 percent, with three or more daily drinks raising it 40 to 50 percent. The authors advise women not to exceed one drink a day.

Alcohol linked to diabetes - study
In a Swedish cohort, total alcohol intake and binge drinking raised the risk of pre-diabetes and diabetes in men while low intake lowered it in women. Reviewers noted the authors skipped their own finding that non-drinkers had the highest risk in nearly every comparison.

Can Moderate Drinking Boost Breast Cancer Risk?
A JAMA study of 105,986 women in the Nurses' Health Study linked 3 to 6 drinks a week to a 15 percent higher risk of invasive breast cancer. The authors call it a small increase, tied most consistently to cumulative alcohol intake across adult life.

Consumption of alcoholic beverages is known to be a human carcinogen - official report
The National Toxicology Program's 12th Report on Carcinogens lists alcoholic beverages as known human carcinogens, citing consistent evidence for cancers of the mouth, pharynx, larynx and esophagus, with risk rising as intake rises, and weaker evidence for liver and breast cancer.

Alcoholic beverages linked to higher risk of breast cancer
News reports saying red wine lowers breast cancer risk overstate the study. Thirty-six premenopausal women drank red wine one month and white the next, and researchers measured only hormones: red wine raised free testosterone and LH and lowered SHBG compared with white.

Drinking alcohol raises breast cancer risk
Women drinking up to six glasses of wine a week were 15 percent more likely to develop breast cancer than non-drinkers, possibly through alcohol's effect on estrogen. Fewer than three drinks a week showed no increase, and researcher Wendy Chen calls the added risk small.
Food
Even moderate drinking may boost breast cancer risk
Among 105,986 nurses followed from 1980 to 2008, with 7,690 invasive breast cancers recorded, 5 to 10 grams of alcohol a day was tied to 15% higher risk and at least 30 grams a day to 51%. The authors stress the study is observational and cannot prove cause.

Does moderate alcohol consumption increase body weight? (PR)
A Spanish review of studies spanning ages, cultures and drinking patterns found the results often contradictory. The authors conclude it is unclear whether alcohol causes weight gain, that any effect may show up mainly in heavy drinkers, and that wine may be more protective.
Cancer
Eating vegetables, fruits cuts risk of cervical cancer
A case-control study of 268 Uruguayan cervical cancer patients linked a mostly plant-based diet to 40 percent lower risk, while women eating red meat and drinking alcohol were 79 percent more likely to be diagnosed. Smoking showed no association in this group.

Alcohol plus energy drink riskier than alcohol alone
In a study of 56 college students, alcohol impaired impulse control whether or not an energy drink came with it, but those drinking both felt more stimulated than those on alcohol alone. The FDA warned four makers of caffeinated alcoholic drinks, including Four Loko's, in November 2010.

Beer drinkers with genetic variant face high stomach cancer risk
In the EPIC study of more than 521,000 adults, people drinking over 30 grams of alcohol a day were 75 percent more likely to be diagnosed with gastric cancer, and heavy beer drinkers carrying the variant rs1230025 fared worst. Wine and liquor showed no association.

Heavy drinking boosts death risk from pancreatic cancer
Tracking 1,030,467 adults from 1982 to 2006, American Cancer Society researchers found drinkers up to 25 percent more likely than non-drinkers to die of pancreatic cancer. Among never-smokers, three or more drinks a day carried 36 percent higher risk. Liquor drove the link; beer and wine did not.

6% U.S. teens ages 12 to 14 drink alcohol
A SAMHSA survey of more than 44,000 respondents found 5.9 percent of 12- to 14-year-olds, about 710,000 teens, drank alcohol in a given month. Most got it free, and 44.8 percent got it from family or at home; only 6.6 percent bought it themselves.

Caffeine can't curb effects of alcohol
Adding caffeine to alcohol did not improve reaction time or driving-test performance among 129 people aged 21 to 30, a study in Addiction found. The authors see little or no protective benefit and call for scrutiny of how caffeinated alcoholic drinks are advertised.

Hangover: What you need to know
A question-and-answer piece explains that alcohol and metabolites such as acetaldehyde drive hangover symptoms, notes an estimated 25 to 30 percent of people seem resistant, and says controlling intake remains the most effective remedy.

Amygdala damage leads to abnormal fear reaction
Researchers describe a woman with bilateral amygdala lesions who showed no normal fear response to snakes, spiders, a haunted house or frightening films while still feeling other emotions. A separate study found alcohol dampened amygdala reactivity to threat in social drinkers.

FDA bans Four Loko, other alcoholic energy drinks
The FDA warned four companies to stop selling caffeinated alcoholic malt beverages, including Four Loko, concluding caffeine is not generally recognised as safe in such drinks because it can mask the cues drinkers use to judge how intoxicated they are.

Don't use alcohol with energy drink
Regulators weighed action against caffeinated alcoholic drinks such as Four Loko after reports of illness and deaths. A study in Alcoholism found that adding an energy drink to alcohol dulled drinkers' sense of impairment without improving motor coordination or visual concentration.
