This paper illustrates how the concept of “Human API” can help cancer post-treatment cancer patients with challenges they face once they are released from the hospital. The results and implications of this semester long graduate project will help illuminate how the Human API through its various data collection methods could potentially play a larger role in extended cancer care. The research will also attempt to determine if hyper-connected networks of individual patients could become effective sources of information for health institutions to engage and connect with patients after treatment or surgery.
