In the present study, we investigated the usefulness of selected metalloproteinases, MMP-3, MMP-7, MMP-10, and MMP-26, as well as CA 125 and SCC-Ag (commonly used tumor markers), in patients with CC (in particular cancer stage subgroups—stages I + II, and III + IV) and patients with dysplasia in comparison to healthy women. This evidence concerns the gene MMP26 and dysplasia.
