Sweet five-year-old Abbey-Rose Navarro is a bright, loving, and playful little girl who has brought endless joy to her family and everyone who knows her. This past week, her parents, Jessica and Jose, received the heartbreaking news no parent ever wants to hear.

What began as a bad cough quickly turned into something far more serious. After days of worsening symptoms and swelling, Jessica followed her mother’s instinct and rushed Abbey-Rose to Nicklaus Children’s Hospital early Sunday morning, praying for answers. After several tests and scans, doctors discovered that Abbey-Rose has been diagnosed with T-cell acute lymphoblastic leukemia (T-cell ALL) — a rare and aggressive form of blood cancer.
