Cancer cure statistics questions
I would caution you against using phrases such as "completely cured" or even "cured". This goes beyond our technical ability to detect the presence of tumor cells within someone's body. All we can conclude is progression-free survival (i.e. living with cancer that does not get worse) or disease-free survival (i.e.  or no signs or symptoms of the tumor). Many of these data are included in cancer trials along with overall survival rates. Some general statistics for many groups of cancers can be found here: http://www.cancer.gov/statistics/find
