In May 2013 the actress Angelina Jolie informed the press that she had undergone bilateral risk-reducing mastectomy (BRRM) because she carried a maternally inherited pathogenic BRCA1 mutation. This decision created huge publicity worldwide [1] and led to enormous interest in hereditary breast cancer/genetic testing. Here we comment on our recently published research article in Breast Cancer Research and provide more recent observations. This reported a 2.5-fold increase in referrals of UK women with family histories of breast cancer 3–4 months following Ms Jolie’s revelation [1]. We also highlighted increased interest in BRRM; however, as it takes 9–12 months from initial BRRM enquiries to the operative procedure, we can now report a similar 2.5-fold increase in uptake of BRRM in the 6–24 months following this. The Genesis Prevention Centre Family History clinic (GPCFHC) covers an extended population of around 5 million. Although the main impact of the Angelina effect was from June to November 2013, this trend continued through 2014 with increased referrals from 201 in January–June 2012 to 388 (odds ratio (OR) 1.93) in January to June 2014 and rising by 366 (OR 2.09) for the last 6 months to give a total of 754 for 2014. Women attending for risk assessment and discussions concerning BRRM, unprompted, still mention the effects of Angelina Jolie on their attendance anecdotally to clinic physicians and still reflect on the impact of her speaking publicly in their pre-surgery consultations with the clinical psychologist in 2015. A clear upward trend in BRRM can be seen starting around 6 months after the news announcement in May 2013 (Fig. 1). The number of high-risk women without BRCA1/2 mutations undergoing BRRM (n = 12; 18 months from January 2011) rose to 52 (18 months from January 2014). The number in mutation carriers rose from 17 to 31. The overall combined rise from 29 BRRMs to 83 was significant (high-risk women at GPCFHC, n = 2012; chi-square p 18 months after testing positive, indicating a delay in decision-making, whereas prior to 2013 the majority of women had BRRM within 18 months of testing positive [2]. There was a slight rise in the number of unaffected women newly testing positive for BRCA1/2 in Manchester from 81 to 116 in the 2 years before and the 2 years after Angelina’s announcement, although this could have been impacted by new National Institute for Health and Care Excellence (NICE) guidelines announced in June 2013 [3]. This research was exempt from ethical approval as this is an audit of clinical service and does not contain identifiable data.

It would be interesting to see results from centres worldwide. Plans to offer breast cancer risk assessment on a population basis could further affect uptake of BRRM [4]. It is also possible that similar effects will be seen on the already increasing rates of contralateral mastectomy in women with breast cancer [5].
