(WGHP) — Susannah and Elizabeth Castle are typical three-and-a-half-year-old girls: playful, energetic and silly. They've come a long way from the conjoined 7-month-old babies we first introduced viewers to in November 2021 as they prepared for a complex and lengthy separation surgery at Children's Hospital of Philadelphia.  "December 10th was actually our third anniversary of their separation so we had a big party and celebrated," said Dwight Castle, the girl's dad who is originally from Winston-Salem and a longtime pastor in Birmingham, Alabama. "We're so thankful to the Lord for that monumental moment that happened three years ago." Cancer diagnosis gives woman perspective on ‘Crazy Perfect Life’ His youngest children, Susannah and Elizabeth, now attend preschool and are making huge gains in their speech. As of this fall, for the first time since birth, both girls are G-tube-free and eating independently. "They're doing awesome. Each has their own particular ongoing challenges that we know of and then there may be more unknowns down the road as well," said Dwight. "So we're tracking those and we're making progress on those but, overall, they're just so happy and sweet." Life seemed to finally be on the cusp of slowing down for Dwight and his wife, Stephanie — as much as it can with five young children. But then, right after Christmas, a peculiar bruise on their otherwise healthy 7-year-old son Judah sent them to the pediatrician. "His numbers came back concerning so they sent us to the emergency room immediately and he had some labs run and it came back that he likely had leukemia or some type of cancer," said Stephanie. "On January 2nd we found out that he has B-Cell Acute Lymphoblastic Leukemia."   Everything happened fast. "That started on a Tuesday, and by Friday, they'd already done multiple surgeries, put in his port in his chest for his treatments and began chemotherapy," said Dwight. Judah will undergo cancer treatment for more than two years. "It's caught us so off guard and seems like such a statistical improbability to experience what we did with the conjoined twins and then this in such a small amount of time, it's kind of blown our minds," said Dwight. "Emotionally, mentally, spiritually, it's very challenging." Kernersville cancer survivor shares story for National Men’s Health Month Dwight and Stephanie say they are leaning into their strong faith and close-knit community to help pull them through. "It's a broken world, but we do believe Jesus is our hope and we do believe that when people walk through hard times, there's hope found in him," said Dwight.
