You asked

I would like to request datasets covering between 2-6 years. This data should include the age, ethnicity (race), diagnosis, family history, dietary history, weight, date of diagnoses, mortality rate, date of death, type of disease, social/environmental factors that influence the diseases and the type of treatment.

We said

Thank you for your query. We hold cancer registration data and mortality data but does not hold the specific data that you asking for. We do not hold ethnicity data, family history, dietary history, weight or social/environmental factor data. We are therefore unable to provide the data that you request. Public Health England (PHE) have undertaken some work on Prostate and Ethnicity analysis (www.ncin.org.uk/view?rid=2635) so it may be worth contacting them.
