This paper introduces a new framework of using Internet of Things (IoT) in the context of cancer treatment. The framework depends on the integration of different stages of cancer treatment including radiotherapy and chemotherapy. At the radiotherapy stage, a mobile application is connected to a cloud to serve online consultation and successive appointments. Likewise, at the chemotherapy stage appointments are given to the patient and online consultation is also accessible. Besides, during the drug infusion process, the patient is tracking to recognize the response of his/her body against the chemotherapy dose. All the appointment features are connected to scheduling algorithms that can be adopted from the recent literature. Moreover, all the lab-test results of patients are uploaded instantaneously to the cloud so that decisions towards the dose amount and its timings are made. Regarding the customized chemotherapy doses, optimization models can be adopted from the recent literature to give the optimum doses. On the other hand, decision support platform can be adopted to check the treatment efficacy of standard protocols.
