Finding Cancer Dataset

I am looking for datasets in relation of Bladder cancer. In particular the dataset should have patient information such as age, type of treatment, sex, mortality, cancer stage and maybe quality life etc.
The datasets are required for statistical analysis in R, in order to analyze the life years gained, quality adjusted life years gained and the cost effective analysis for the different subgroups like sex, age, cancer stage etc.
In case data of bladder cancer are not available, I am open to discuss about data for other cancer type.
Please note that the source reference of data is required.
