Now there are some risk factors you can control. Be aware of them – after all, prevention is better than cure.

Physical inactivity

Physical activity has been associated with a reduced risk of breast cancer in both premenopausal and postmenopausal women. A 2013 meta-analysis of 31 studies found that average breast cancer risk was reduced by 12 percent when women were frequently physically active. Try to aim for 30 minutes a day, five days a week to reap the benefits.

Being overweight or obese

According to numerous studies, having a BMI over 25 can increase your risk of cancer. It’s unclear why, but it could have something to do with the lifestyle overweight people lead. One study found that among postmenopausal women, those who are obese have a 20 to 40 percent increase in the risk of developing breast cancer compared with normal-weight women.

Hormone replacement therapy

Current or recent past users of hormonal replacement therapy (HRT) have a higher risk of being diagnosed with breast cancer. There are two common kinds of HRT: combination HRT (oestrogen and progesterone), and oestrogen-only HRT. According to, combination HRT increases your risk of breast cancer by 75 percent, even if you only used it for a short amount of time.

Having a baby after the age of 30

The older a woman is when she has her first baby, the higher her risk of breast cancer. This is due to being exposed to more oestrogen over her lifetime, and an increase in oestrogen can promote the growth of breast cancer cells. Also, as pregnancy progresses, the breast cells grow, which can cause genetic changes to cells.

The chances of genetic changes increase with age, making you more susceptible to breast cancer as time goes on. Women who carry a mutated version of the BRCA1 gene, which increases the lifetime risk of breast cancer, actually reduce their breast cancer risk 32 to 49 percent if they breastfeed for up to two years.

Drinking alcohol

Like tobacco, alcohol has been linked to an increased risk of cancer. Researchers are still trying to figure out why, but it could be linked to the fact that alcohol may cause the breakdown oestrogen, which increases the amount of the hormone in the blood. Having more oestrogen in the body is a risk factor for breast, ovarian and uterine cancers.
