We are having a school project on a mathematical model of tumor growth. We would like to compare our model to the real data. Despite a lot of search we couldn't find any open data on the web. Hence, can anyone recommend a resource for the datasets of tumor cells growth?
EDIT: It seems that we rather need a dataset from test labs, like tumor growth data in mice, rats etc. The reason for that is that we need a data of unrestricted tumor growth. The data from humans is most of the times affected by different treatments to prevent the growth of the cells. Please correct me if I'm wrong, because I'm not a biologist, I'm a mathematician.
