Speaking outside the Pink Lotus Breast Center in Beverly Hills, Dr. Kristi Funk said the clinic "applauds Angelina Jolie's bold choices regarding her BRCA mutation."
"We hope that the awareness she is raising around the world will save countless lives," she said in a one-line statement, adding that further details would be released in due course.
On its website the clinic promised to reveal "behind the scenes" details about Jolie's decision, announced earlier Tuesday in a piece in the New York Times, to undergo a preventive double mastectomy.
In the piece, the Oscar-winning actress -- whose mother Marcheline Bertrand died of ovarian cancer at the age of 56 -- encouraged other women to address threats to their health.
She said she was confirmed as having the "faulty" gene, BRCA1, that doctors said gave her a 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer.
The 37-year-old had three months of grueling medical procedures including breast reconstruction, ending in late April, she said.
