Abstract: Data mining tools are giving successful result for disease diagnosis where it is one of the applications. Widely used in classification and prediction technology in the field of bioinformatics. In this paper diseases such as diabetes and hepatitis has been analyzed and compared using data mining applications. It also summarizes some techniques on medical field (diagnosis and prognosis). To develop disease estimation process using data mining technique it is focused on current research which is being carried out.

Keywords: Data mining techniques, Data mining applications, Hepatitis, Diabetes, Disease diagnosis, Classification, prediction.
