Angelina Jolie’s aunt died of breast cancer on Sunday, nearly two week’s after the actress’s brave decision to tell the public that she had undergone a preventative double mastectomy. Debbie Martin, 61, had the same mutated BRCA1 gene that Jolie inherited, Martin’s husband said. Jolie’s mother, Marcheline Bertrand, who also died of breast cancer, was Martin’s sister. Martin said that if they had known that his wife had the gene, “we would have done exactly what Angelina did.”
