Family members and other women in the entertainment community are applauding Oscar winner Angelina Jolie for revealing Tuesday that she underwent a double mastectomy after discovering she was at high risk for breast cancer.

"Having witnessed this decision firsthand, I find Angie's choice, as well as [that of] so many others like her, absolutely heroic," her fiance, Brad Pitt, told the London Evening Standard. "I thank our medical team for their care and focus. All I want is for her to have a long and healthy life, with myself and our children," he continued. "This is a happy day for our family."

Jolie's brother, James Haven, said in a separate statement, "My sister like our mother always put her children first. I am so grateful to be her brother."

E! News co-anchor Giuliana Rancic, who underwent the procedure in Oct. 2011 after being diagnosed with breast cancer, also tweeted her support: "Proud of her for using her incredible platform to educate women."
