Pushing through her emotional and physical pain with grace, Allyn decided to take a chance and enter a "Sports illustrated" swimsuit model search. Out of the 7,000 entries, she was one of the chosen 16 to walk in Miami fashion week and became the first woman with a double mastectomy to model for "Sports illustrated." Please welcome the very inspiring Allyn rose. Hello, Allyn. Nice to see you. Nice to meet you. You look fabulous. Thank you so much. So nice to have you here. Have a seat. What a story. What a story. I want to start by taking you back a little bit. How did you handle emotionally losing your mother, your grandmother, your aunt by the time you were 16? So, obviously losing those very powerful figures in your life was -- it was a challenge and I think the worst part of all of it is knowing that you're going to have to spend the rest of your life not experiencing those crowning achievements in your life with that support system. So knowing that I had a family health history that included a lot of breast cancer, I knew that having preventative surgery was the right step F me. Yeah, I just didn't want to suffer the same fate as my mom. I know you speaking out has touched lives and that's a lot of the reason you wanted to speak out originally. Do people reach out to you to say thank you? They do. The survivor, thriver community is incredible and I am so touched every time someone writes me a message and says thank you because I've had a mastectomy and I never thought that I would see someone like me modeling for "Sports illustrated" and I'm so fortunate. I work with an incredible foundation called the airs foundation that helps women who can't afford it with the funding after a breast cancer diagnosis. In particular, a woman named Renee reached out to you as well? There was. When I first went public with my story I was able to come here on "Gma" and it was a life changing moment to share my story for the first time and this woman, Renee, reached out to me on Facebook and said, you know, you're sitting there as a 24-year-old talking about your future husband, your future children and wanting to be around for them. She said, I found out that I had the breast cancer gene mutation and I struggled with whether or not to have the surgery, and I have a husband, I have children. She said if you can do it, I can do it, and I just scheduled a consultation with my doctor and you might have just saved my life. And, it gets me choked up every time I talk about it because I remember that moment so vividly and it has been the driving force for me to keep sharing my message even when I think that maybe I'm not doing the right thing or putting the right messaging out all the time but to have someone like that share that moment with me was life changing. It's amazing sometimes you don't realize the impact you have on strangers or people that -- other people. Absolutely. You've never met Renee. I haven't. Renee lives in Florida. We're Facebook friends and chat from time to time but I've never had the chance to meet her. You want to meet her today? Renee, come on out. Hey, Renee. I'm going to cry. Renee, we've heard Allyn say all these amazing things -- I'm shaking. -- About you. Is there anything you want to say to Allyn? First of all, I want to say thank you. Your courage and your strength helped me realize that I could -- I mean, you are a young, beautiful woman. I'm just an average woman who, looking at you, I just knew that your strength gave me strength to turn to my husband, speak to my husband, go to my family, speak to my mother, my father, my brother and speak to them about this decision, and they were all behind me 100%. My mother calls me her brave heart. This is a gift to my family that you gave. You helped save my life, Allyn, and I am so grateful.
