This study will assess the impact of virtual reality (VR) in decreasing procedural pain related to subcutaneous port (SCP) access in children with cancer. The study is a pilot-randomized controlled trial (RCT) using a cross-over design that will provide us with detailed information on the feasibility of implementing our trial protocol in a future multi-center RCT as well as preliminary estimate of VR treatment effect on children with cancer undergoing SCP access, including child and parent factors potentially associated with VR distraction treatment efficacy.
