Breast cancer is one of the most common types of cancer worldwide, with around 2.3 million women diagnosed with the disease every year. In the UK alone, it is estimated that one in seven women will develop breast cancer at some point in their lifetime.
The biggest determinants for developing breast cancer are age and being female. But other lifestyle factors, such as weight, how much you drink, whether or not you exercise, and hormone levels, can also play a smaller part in elevating your risk.
