Hopefully, she's made the right choice, but as all readers of this blog know, a double mastectomy is no guarantee that the cancer will never recur. She made the same choice my first wife did, and hopefully it will work for her. I wish Christina all the best and hopefully she will continue to have a long, healthy life and career.
Perhaps the last high-profile celebrity to have had similar surgery was Ann Jillian, who had appeared in sitcoms like "It's A Living" and "Jennifer Slept Here". I don't think Ann underwent reconstruction surgery like Christina plans to, which meant less daring waitress costumes for her when she returned to "It's A Living" after her surgery.
