Every month now there is another study showing how the dramatic increase in drinking is a key reason for the dramatic increases in breast cancer in younger and younger women.
“Alcohol is related to both premenopausal and postmenopausal breast cancer. And the more you drink, the higher your risk. The highest risk is in women who started consuming alcohol early and continued. We now see a 17% increased risk with only one drink every other day”
Dr Walter Willett, chair of the nutrition department at the Harvard School of Public Health, September 2014.
Dr Willett and colleagues tracked nearly 6,900 teenagers aged 13-20 for five years, monitoring alcohol intake and all the other risk factors.
They found that each daily serving of alcohol was linked to a 50% higher risk of breast disease.
