Kidney Tumor cancer is difficult to detect and can be difficult for doctors to detect, the growth of abnormal in some may lead to cancer or may get worse in another way which can affect daily activity. the main objective of this research titled " kidney tumor cancer detection using Yolo deep learning algorithm “is to build a deep learning model that will facilitate the way used to detect the kidney tumor cancer which used to take long to get a patient’s results and not much trusted which can lead to serious cancer. The usual method to detect kidney tumor cancer is to use Magnetic Resonance Imaging scan to get images and be handed over to doctors to study on them which used to take long time to study on it and some decide without having much experience, some decide based on their feelings or some may be stressed by the work they have done and they decide quick without being diligent on what they currently have. this developed deep learning based kidney tumor cancer detection and diagnosis system will automatically detect and classify important regions on an input biopsy image. this research will increase accuracy in results which come from radiologist analysis of MRI image and will also reduce time which used to take to get result not only that but also the chance of getting cancer from kidney tumor cancer will be reduced for that kidney tumor cancer surgery will be right way after passing MRI image into my kidney tumor cancer detection using Yolo deep learning algorithm to detect if it is kidney tumor cancer or not.many new treatments for kidney tumor cancer have been developed, some are currently being developed by scientists. this research will provide kidney tumor cancer detection, diagnosis, and treatment information that offers new hope to the lives of kidney cancer patients. In this research, it is aimed to detect kidney tumor cancer using Yolo deep learning algorithm.
