in women were caused by past or current alcohol intake. The World Cancer Research Fund panel report Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective finds the evidence "convincing" that alcoholic drinks increase the risk of the following cancers: mouth, pharynx and larynx, oesophagus, colorectum (men), breast (pre- and postmenopause). Even light and moderate alcohol consumption increases cancer risk in individuals, especially with respect to squamous cell carcinoma of the esophagus, oropharyngeal cancer, and breast cancer. Acetaldehyde, a metabolic product of alcohol, is suspected to promote cancer. Typically the liver eliminates 99% of acetaldehyde produced. However, liver disease and certain genetic enzyme deficiencies result in high acetaldehyde levels. Heavy drinkers who are exposed to high acetaldehyde levels due to a genetic defect in alcohol dehydrogenase have been found to be at greater risk of developing cancers of the upper gastrointestinal tract and liver. A review in 2007 found "convincing evidence that acetaldehyde... is responsible for the carcinogenic effect of ethanol... owing to its multiple mutagenic effects on DNA." Acetaldehyde can react with DNA to create DNA adducts including the Cr-Pdg adduct. This Cr-PdG adduct "is likely to play a central role in the mechanism of alcoholic beverage related carcinogenesis." Alcohol's effect on the fetus Fetal alcohol syndrome or FAS is a birth defect that occurs in the offspring of women who drink alcohol during pregnancy. More risks than benefits according to a survey of current knowledge. Alcohol crosses the placental barrier and can stunt fetal growth or weight, create distinctive facial stigmata, damaged neurons and brain structures, and cause other physical, mental, or behavioural problems. Fetal alcohol exposure is the leading known cause of intellectual disability in the Western world. Alcohol consumption during pregnancy is associated with brain insulin and insulin-like growth factor resistance. Short term-term effects of alcoholism on family and children Children raised in alcoholic families have the potential to suffer emotional distress as they move into their own committed relationships. These children are at a higher risk for divorce and separation, unstable marital conditions and fractured families. Feelings of depression and antisocial behaviors experienced in early childhood frequently contribute to marital conflict and domestic violence. Women are more likely than men to be victims of alcohol-related domestic violence. Children of alcoholics often incorporate behaviors learned as children into their marital relationships. These behaviors lead to poor parenting practices. For example, adult children of
