She has not been seen on a movie set since it was announced she underwent a preventative double mastectomy following the discovery that she had an 87% chance of developing breast cancer.But on Sunday, Angelina Jolie stepped back onto the set of her latest project Unbroken, a film she which she is directing.It appears to be the first time that the 38-year-old actress has been back in the movie world since her brave decision, and the star looked elegant in a long skirt and blouse as she talked to crew members in Los Angeles.Angelina's decision to undergo the operation sent shock-waves around the world when it was revealed earlier this year.Following the announcement the star made an appearance on the red carpet in the summer, supporting her husband Brad Pitt's movie World War Z.But now it seems the star is concentrating solely on her own career, as she directs her new movie which has been written by the Coen Brothers.The movie chronicles the life of Louis Zamperini, an Olympic runner who was taken prisoner by Japanese forces during World War II.Carrying an over-sized handbag and a huge folder, it appears Angelina is clearly putting a lot of research into the project.Last week, the star's doctor - the renowned breast cancer surgeon Dr. Kristi Funk - spoke out about the star's decision for the first time.Dr. Funk, who has also treated singer Sheryl Crow, spoke to Mario Lopez in an interview with Extra revealing that Angelina's decision was not based out of 'fear'.'She didn't have [the double mastectomy] right away, but probably knew with her family history that it was a choice she would eventually make,' she said.Adding: 'Her decision was not made overnight. It wasn't based in fear.'
Angelina made her decision to undergo the operation after she was found to be carrying the RCA1 cancer gene, which also gives her a 50 per cent risk of ovarian cancer.When asked how Angelina is doing now, she replied 'perfect' describing husband Brad as being 'the coolest' throughout the treatment.Dr. Funk revealed that Angelina knew that she was at some stage going to go public with the news in order to raise awareness about breast cancer amongst women.She explained: 'I knew that was her intention. She is just philanthropic to the core. She could never keep this a secret, and be who she is! She is someone who wants to save lives and she is doing that every day!'Asked whether Dr. Funk feels more pressure working with celebrities such as Angelina, she explained that she delves into a 'slightly more creative mode'.She revealed: 'Knowing that it would be publicly scrutinized…I developed some really new and beautiful changes to both the preparation for surgery, and the actual operation.'
