3000 New Zealand women are diagnosed with breast cancer every year, so knowing how to protect yourself is important. Here are two simple changes you can make to reduce your risk: Alcohol increases breast cancer risk, exercise lowers it.
New research suggests that as little as 10g of alcohol per day – the equivalent of a small glass of wine or beer – raises the risk of premenopausual breast cancer by five per cent. The same amount of alcohol raises the risk of postmenopausal breast cancer – the most common form of breast cancer – by nine per cent. Conversely, moderate exercise decreases the risk of both pre- and postmenopausal cancer. The most active postmenopausal women are 10 per cent less likely to develop breast cancer compared with the least active women. For premenopausal women, the drop in risk is 17 per cent.
