According to a new report by the World Cancer Research Fund and the American Institute for Cancer Research on Wednesday, an average of 10g of alcohol a day is associated with a five per cent risk increase of breast cancer in pre-menopausal women and nine per cent in post-menopausal women.
It finds that greater weight gain or body fatness in adulthood, for instance, increases the risk of postmenopausal breast cancer.
It also points out that mothers who breastfeed are at lower risk for breast cancer.
Dr. Anne McTiernan, said: “with this comprehensive and up-to-date report, the evidence is clear: having a physically active lifestyle, maintaining a healthy weight throughout life and limiting alcohol – these are all steps women can take to lower their risk.”
McTiernan, is the lead author of the report and cancer prevention expert at the Fred Hutchinson Cancer Research Centre.
According to WHO, globally, breast cancer is the top cancer form in women,.
WHO also said that breast cancer can occur in men, rare though, accounting for less than 1 percent of cancer incidences and mortality among men in the U. S.
The report also revealed, for the first time, that vigorous exercise such as running or fast bicycling decreases the risk of both pre- and post-menopausal breast cancers.
