Abstract.In this paper, we suggest some rules which are considered when we give a similarity measure for measuring of the degree of similarity between fuzzy rough sets and their elements. We propose a new similarity measures for measuring the degree of similarity between fuzzy rough sets and their elements. Finally, we illustrate the problem in the context of colorectal cancer diagnosis by similarity measure between fuzzy rough sets.
