It is recommended to consult a doctor in time to clarify the nature of the cysts and treat them actively. Physiologic ovarian cysts are also known as functional cysts. With the changes in the body’s menstrual cycle, the follicles in the ovaries grow and may form cysts, including follicular cysts and corpus luteum cysts. These cysts usually do not cause health problems or clinical discomfort and may change and disappear with the menstrual cycle. Pathologic cysts of the ovaries are associated with diseases, including dermoid cysts, ovarian cystadenomas, and endometriotic cysts. These pathologic cysts can persist for a long time, grow in size, and have a risk of cancer. If they are not treated in time, ovarian torsion and rupture of the cyst may occur. When ovarian cysts are present, it is necessary to actively consult the doctor and follow the doctor’s instructions for rational treatment.
