Non-redundant ovarian cysts include follicular cysts, corpus luteum cysts, lutein cysts, inflammatory ovarian cysts, polycystic ovaries and ovarian chocolate cysts. Ovarian cysts refer to the formation of cystic masses in the ovary and are divided into tumorigenic ovarian cysts and non-tumorigenic cysts, most of which are referred to as non-tumorigenic cysts in daily life. Non-neoplastic ovarian cysts, or non-tumor ovarian cysts, are mostly functional cysts of the ovary, which are generally not tumors and are relatively small, and can usually subside on their own, while some larger cysts require surgery. Once a cyst is found in the ovary, it is important to go to the hospital in time to determine the nature of the cyst and make a clear diagnosis based on the size of the tumor and other characteristics. If the cyst is tumorigenic, surgery should be performed as soon as possible, regardless of the size of the cyst.
