Caveolin-1 (Cav-1) is well known as a principal
scaffolding protein of caveolae which are specialized plasma
membrane structures. The role of Cav-1 in tumorigenesis of
breast cancers is relatively less studied. The aim of the present
study is to describe the biological roles of Cav-1 in breast can-
cers considering its contrasting dual functions as an oncogene
and as a tumor suppressor. This study included 71 females with
breast cancer who had been histopathologically diagnosed in
Private Gunes Pathology Laboratory between the years 2007,
and 2012. The mean age is 52.48 ± 12.8 years. Patients were
followed up for a mean period of 47.97 ± 20.48 months. We
didn’t determine Cav-1 positive tumor cells. In 36 cases
