Play therapy is a form of psychotherapy that uses play to help children ages 3-12 express and process their experiences and feelings. It allows children to communicate nonverbally through play, their natural form of expression. Play therapy for pediatric cancer patients aims to reduce stress, release tension, and encourage positive development. It involves various types of play like role play, fantasy play, arts and crafts, and activities centered around medical themes and experiences. The goal is for children to develop self-confidence and coping skills to deal with their illness and hospitalization. Play therapists use toys, games and a safe environment to help children communicate freely without pressure.
