Bad habit: Drinking one glass a day from your early teens can increase risk of cancer
Women who drink just one glass of wine a day in their teens and early twenties could be increasing their risk of breast cancer by a third.
Scientists have found that consuming fairly small amounts of alcohol early on in life has harmful effects on breast tissue.
Those who drank the equivalent of one glass of wine a day between the age of their first period and when they gave birth to their first child increased their risk by a third.
US researchers believe that the breast tissue of young women, which is still developing, is highly susceptible to the harmful effects of alcohol.
