TheBRCA1 is present in everyone but only mutates in one in 1,000 people. Anyone with the mutation has a50-80% chance of developing breast cancer. But Jolie’s risk figure was calculated to be even higherbecause of other factors, including family history.“There are various computer programs where you can input genetic information, family history andother things and it will calculate a figure, which is why she’s got this very precise sounding number,” saysDr. Kat Arney, a senior science manager at Cancer Research UK.Breast cancer is already “the top cancer in women both in the developed and the developing world”,according to the World Health Organization - and in many countries, it’s becoming more common.Overall, a woman living in the UK has a 12% chance of getting breast cancer during her lifetime. It’sthe same in the US. But increasing longevity isn’t the only reason for the high incidence of breastcancer.“There is an increase in rates in younger women and it’s for a number of reasons. We know thatwomen’s lifestyles are changing and being overweight and drinking a lot of alcohol is linked to breastcancer risk,” says Arney.Changes in reproductive habits are also a factor. According to Cancer Research UK, the relativerisk of developing breast cancer is estimated to increase by 3% for each year an adult woman delaysbecoming a mother. Women who breastfeed also reduce their risk. The longer a woman breastfeeds,the greater the protection. It’s estimated that risk is reduced by 4% for every 12 months ofbreastfeeding. This may explain why women in richer countries have a higher risk of breast cancer.African women are four times less likely to get the disease because they have children at a younger age,have more of them and breastfeed them for longer.
