Cancer is expensive. In addition to the cost of treatment itself, there is the financial burden of a parent having to take off work, or a family having to move closer to a hospital. Medical crowdfunding has emerged in recent years as a way for people to cover the costs associated with cancer and cancer treatment. In 2014, GoFundMe hosted 600,000 campaigns, raising US$150 million. However, there are a number of ethical concerns. Among these are the fraudulent campaigns, set up "on behalf" of a patient's family, but the family never sees a dime.
