A glass of wine each evening is enough to increase your risk of developing cancer, women are being warned.
Consuming just one drink a day causes an extra 7,000 cancer cases - mostly breast cancer - in UK women each year, Cancer Research UK scientists say.
* A unit is 8g alcohol, nowadays many wines and beers a sufficiently strong that they contain 10g per serving (small glass, half a pint) and this study uses 'a drink' to mean 10g alcohol.
** These confidence intervals are based on a 'floating absolute risk' model which is controversial and results in narrower CIs than conventional techniques.
***This is dodgy, to multiply the 118 cases of cancer by the estimated relative risk at 10u/day of 1.13 (which is what they seem to be doing) would only be valid if the 118 cases was from women in the lowest risk group - those drinking <= 2u/week - but we know that many women do drink more than this (nearly half in this study), and the overall cancer rate therefore already includes this extra alcohol related risk. However, if I adjust my above figures to account for this it doesn't make much difference - giving an additional 11 cancer per 1000 women, and thus absolute increased risk of 1.1%.
