OpenCancer is an AI-powered service designed to help people with cancer and their caregivers better understand care options and prepare for informed conversations with clinicians. Its tools provide plain-language answers about diagnoses, treatments, medical reports, and clinical trials, with sources that include NCCN patient guidelines and PubMed. Users can ask questions without signing up, upload records to receive guidance tailored to their case, and choose to have PhD cancer scientists review their information. OpenCancer says expert reviews are free and that responses can arrive within 24 hours.

The platform also offers a Care Circle for organizing support around someone’s care, a records vault, a services directory, an answers library, and resources on clinical trials and financial assistance. Built by cancer survivors and a PhD science team, OpenCancer emphasizes that records are shared only with the user’s permission and are never sold. The service aims to help patients and caregivers navigate complex information with clearer, more relevant answers. It notes that its information is not medical advice.
