'Angelina effect' more than doubled breast cancer tests in UK, study finds

September 19, 2014  19:36

Referrals for genetic breast cancer tests more than doubled in the UK as a result of what doctors have described as the "Angelina effect".

In May last year, actor Angelina Jolie revealed that she had undergone a double mastectomy to avoid breast cancer, The Guardian reminds.

She took the decision after testing positive for the BRCA1 gene mutation that greatly increases the risk of developing the disease.

A study has measured the impact of her announcement on women in the UK. It shows that in June and July last year, the number of GP referrals for genetic counselling and DNA tests for breast cancer mutations increased two and a half times on the same period in 2012.

Referrals remained double the previous year's figure from August to October.

Most of the extra women seeking help had a family history of breast cancer.

Professor Gareth Evans, from the charity Genesis Breast Cancer Prevention and St Mary's Hospital, Manchester, who led the study published in the journal Breast Cancer Research, said: "Angelina Jolie stating she has a BRCA1 mutation and going on to have a risk-reducing mastectomy is likely to have had a bigger impact than other celebrity announcements, possibly due to her image as a glamorous and strong woman.

"This may have lessened patients' fears about a loss of sexual identity post-preventative surgery and encouraged those who had not previously engaged with health services to consider genetic testing." Defective versions of BRCA1 and its sister gene BRCA2 are together responsible for about a fifth of breast cancers. Women who inherit BRCA1 have a 60% to 90% risk of developing breast cancer. BRCA2 increases the risk by 45% to 85%. Both gene mutations also raise the risk of ovarian cancer.

Under NHS guidelines, women can qualify for BRCA testing if one of the mutations has already been identified in a relative or they have a strong family history of breast cancer.
