It's Breast Cancer Awareness Month so you've probably read lots of advice about how to lower your risk of developing the disease. But what if you have a family history of breast cancer? Surely all the advice about exercising and keeping your weight down isn't worth much if the risk is already in your genes?
Not according to US experts, who say a breast-healthy lifestyle does help lower your risk - whether or not you have a family history of breast cancer.
Writing in the journal Breast Cancer Research, the experts say it's good news for women who have a close relative who's had breast cancer.
When the disease runs in your family, they say, you could feel your risk is out of control. But the researchers claim a family history of the disease could partly be caused by unhealthy lifestyle behaviours that have been passed down for generations. And - having studied more than 85,000 women - they conclude if you change those behaviours, you could reduce your risk.
According to leading breast surgeon Lester Barr - chairman of the UK-based Genesis Breast Cancer Prevention Appeal - the most important steps you can take to reduce your risk of breast cancer include being breast aware, losing some weight (if you need to), being physically active, drinking alcohol sensibly and aiming to stop taking the pill around the age of 30 (and when the time comes for HRT to limit your use as much as possible too).
Have you changed any aspect of your lifestyle to reduce your risk of breast cancer or another illness?
