[USA Today] Twins have a unique bond, but for sisters Dawn Ardolino Policastro and Allison Ardolino Dinkelacker, that bond runs especially deep.In 2009, when Allison was 30 weeks pregnant with her first child, she was diagnosed with stage-3 breast cancer, Mineola, N.Y., Patch.com reported. Doctors said she needed to begin chemotherapy immediately, and her son was delivered through an emergency C-section at 31 weeks.
Six years later, Allison was cancer-free but unable to have another child. Her identical twin, Dawn, accompanied her to a doctor's appointment and made an unlikely proposition, according to Patch.com.
"We sat in my oncologist's office, and he said to me ... 'You will never be able to carry another child,'" Allison wrote in a Facebook post. "Well before [the doctor] even finished his sentence, Dawn jumped in and said, 'It doesn't matter because I am going to carry their child,'"
