Age:
Risk
of developing breast cancer increases with age. It is most common among women
over 50 who have been through the menopause. Most cases of breast cancer occur
in women over 50.
Women who are 50-70 years of age are advised to go for breast cancer screening every three years.
Overweight
and Obesity
Women who have passed through the menopause and are overweight or obese, are more likely at risk of developing breast cancer. It is believed to be linked to the amount of oestrogen in your body, because being overweight or obese after the menopause leads to more production oestrogen.
Exposure to
Oestrogen:
For example, if you started your periods at a young age and experienced the menopause at a late age, you'll have been exposed to oestrogen over a longer period of time. Likewise, not having children, or having children later in life, may slightly increase your risk of developing breast cancer because your exposure to oestrogen is uninterrupted by pregnancy.
