Lucy Davis, an acclaimed British actress who gained stateside success on shows like Netflix's "Chilling Adventures of Sabrina" and Disney Channel's "The Villains of Valley View," has announced that she has incurable breast cancer. "I wanted to share something with you all that I've kept to myself for a while but for various reasons would like to share now," begins Davis' heartbreaking Instagram post. "A year and a half ago, I was diagnosed with Stage 4 Breast Cancer, which has metastasized to my bones — specifically to my spine, right hip, and my ribs. The cancer is incurable, and too late for chemo." And cancer has not disappointed in that regard; there's a lot I have learned from it, and I'm grateful for that."
