Open Source Cancer Survivorship is a method for clinicians to harness the power of peer review and transparency. OSCS is formed to educate about and build bridges amongst different Oncology practices that are caring for survivors. One of our most important activities is to create an environment for the sharing of information within the cancer survivorship clinical community. The main principle of OSCS is to encourage the diversity of ideas and approaches to caring for survivors in the setting of peer examination. The motivation is through the sharing of each other's documents and clinical designs at no cost, our field will advance more rapidly than the traditional academic model. The expectation of OSCS is that we will all use each other's materials and improve upon it. The understanding is that everyone will then return the enhanced product to the community to again contribute to the unending cycle of augmentation.
