A cancer survivors support group called FlatToppers Pride, in partnership with Play Out aim to empower the underrepresented, flat-chested women.
One of the models, Melanie Testa, said that the way society reflects the image of scarred women affected by breast cancer, has a big impact on those who are newly diagnosed.
The disease shouldn't be an assault on woman's gender identity, sexuality, femininity, body acceptance or self-confidence, said Testa.
"Breast cancer is a fact of the human experience. It is vitally important to place survivorship in the context of empowerment, said Jodi Jaecks, another model.
"I think that my natural androgyny and sexual preference have given me the advantage of self-acceptance far outside of cultural gender identification or definitive norms. This self-assurance informed not only my choice to have the double mastectomy, but the certainty that my choice would serve my self-confidence and strength moving forward in my life."
