Transcript for Robin Roberts' Recovery: Why She's Ready for Return
it together. Joining us, now, two, key members of robin's medical team. Sergio jer ralt. And gail roboz. We have robin's nurses, right across the way. There they are. I didn't recognize them. Usually, I saw this much of them. They always had a mask on. But looking wonderful. Looking fantastic. I have to ask you, starting out, for all of us that care about robin. It's on the top of our minds. Are you sure she was ready to come back right now? And that you didn't let her out a second before she was ready? Well, this is a collaboration. She didn't strong-arm us. She didn't force us to do it. But she was looking great and feeling very well. And all the numbers were going in the right direction. We didn't exactly have in mind an interview with mrs. Obama and the oscars for this weekend as an easy start. I will attest. That was not right up there with what we had in mind for easing back in. But dr. Geralt and I are learning to cope. And we're hopeful that the strength you're showing right now is going to keep on going. There is a certain point, how will you know, we know, robin know, when she's not ready and should take a day. We came into this as a test run. We started with dry runs. Wake up at 3:00 in the morning. See how it goes. Go into the studio. Do what you do as a mock run. Today is the dress rehearsal. It's her first show. We're going to see how she feels tomorrow. Tomorrow, we're going t debrief. Sit down and talk. How was it? How tired are you? And depending on how this marathon weekend looks and how she feels on monday, will decide, you know, is it good to do three times a week? Five times a week? You have to restrain the athlete in you, don't you? Pushing the envelope here. I do. But I have to say, as they know, I have listened to them. And I saw dr. Giralt yesterday. And we looked in each other's eyes. And we talked about this morning and how I would feel. And I know a lot ofs adrenaline. And I want to see how I feel. And he was very honest in saying, some of the patients, they go back a little too soon. And the next morning, they can't get up. But I have to say, physically, physically I feel I have -- i have better platelets than sally-ann right now. So, I'm very grateful. When you check in with yourself, what are you going to be listening for, thinking about? I will be listening to them, going back every couple of weeks. We have another bone marrow test in two weeks. But just really listening my body. And that's what's so important for everyone. I was disappointed, of course, when this happened. Being that I had taken such good care of myself. And I think that they will tell you, part of the reason I was able to recover as I have so well, because I had done things before I got to this point. That I was in relatively good health before that time. And I want to say that, well, thank you for everything. But also, thank you for making me a part of clinical trials. I have benefited from those who made themselves available. The standard treatments of today are developed because people, you know, patients before you participated in clinical trials. And in a certain sense, it's our obligations as physicians and patients of today, to develop the standard of care for the patients of tomorrow. You participate in a clinical trial, looking at a different way of preventing one of the most feared of transplants when the graft rejects the patient. It's been successful. And we hope this will be establishing a new standard of care. What are the milestones we're looking for right now? We're looking at time. Time passing is a good thing. As the weeks and months go by, and things start feeling more normal and there are no medications and fewer blood tests and fewer appointments, things start feeling better and better. But we're going to be on your case. That is the honest truth. And we are not letting you go yet. And I said it before, I don't care who the interview is with. If you're not well enough to go, you're not going. That's what I want to hear. Robin thanks you. And we want to thank you, well. I want to say this. The nurses, looking over at them, the technicians, the passion and compassion that you have for all of your patients, is admirable. People have given me a standing ovation. We need to give these people a standing ovation. Thank you. Even in the control room. Thank you. And while we're all standing, a very special edition of "20/20" this friday night about robin's journey. At 10:00, 9:00 central, right here on abc.
