Ultrasound examinations are performed and indicate the presence of a mass on the right side of the ovary or presence of a mass for a variety of reasons. When there is an endocrine hormonal disorder that causes hormonal disruption of the normal function of the ovary, it can also cause the ovary or the presence of a mass to occur. Due to hereditary factors, ovarian cysts are twice as likely to occur in families due to genetic factors, which may also cause ovarian masses. In the case of teratoma, there are symptoms of teratoma formation due to the differentiation of cells and tissues. If the ovarian mass is more than four centimeters, early surgery should be performed as soon as possible to avoid prolonged presence of the mass affecting ovarian function and causing irregular menstruation and pregnancy.
