just ask genae girard. doctors suspected that her cancer was also genetic, she, too, got tested, and her results were positive. doctors recommended genae have a double mastectomy and have her ovaries removed. >> which was a very tough decision. i mean, i'm still in my 30s, and this is going to change my life, whether or not i ever want to have children. and that was a big deal. >> so she did the obvious-- sought a second opinion, another genetic sequencing from a different lab, but her doctor told her that wasn't possible. >> i think myriad laboratory is a very reputable company, but i know for a fact that there's human error that exists in laboratories, and i would have felt a lot better about these decisions if i had that. >> so whether you like it or not, myriad owns that gene that's in both of you. >> yes. >> correct. >> no one invented my gene. they didn't change or alter my gene. all they're doing is actually looking at it. it's crazy. >> lori andrews agrees. she's a professor at chicago kent college
