Modern medical diagnostic tools have greatly improved medical care. However, they can also be troublesome and burdensome for patients. Gynecologic ultrasound is the most common auxiliary examination method, often see the pelvic cavity without echo, regardless of the size and internal characteristics of all reported ovarian cysts, so that patients fear; coupled with individual irresponsible doctors indiscriminately surgical removal, to give patients a head-on, not only to add insult to injury, adding fuel to the fire, but also to make the patient embarrassed. In terms of ultrasound, the absence of echogenicity in the ovary is indeed detected and is collectively referred to as ovarian cysts. In this way there is a mixture of fish eyes and flesh, making it difficult to distinguish. Doctors are not rewarded for their good intentions, and patients are deeply grateful for procedures that should not be done. This is both puzzling and understandable. Why is this? The patient does not understand, anyway, the long tumor should be operated, the natural, unquestionable; confused doctors and not very clear, just the water to push the boat. The fact that the ovarian cysts themselves are puzzling is not that scary, and there is no need to make a fuss. Why do you say so? It’s just that we don’t know enough about ovarian cysts and they are often covered up by exaggerated words and their true nature is infinitely magnified. Although there are many different kinds of ovarian cysts, apart from physiological cysts, most cysts are also benign tumors. If menstruation is scanty or amenorrheic, as well as obesity with heavy body hair, and multiple cysts are found inside both ovaries, usually cysts <0. 8 cm and >10 per side, combined with endocrine changes, polycystic ovary syndrome is often considered clinically, and in most cases treated with medication, but cycle therapy is needed, and laparoscopy can be considered individually. There are also cases of normally normal menstruation with occasional menstrual abnormalities, and ovarian cysts are found, usually <5 cm, thin walled and with good internal translucency, often considered follicular cysts, which can be treated symptomatically and rechecked in two months. Of course, there are also ovarian cysts found during physical examination in the second half of menstruation, rarely >5 cm, with fine internal reticular echogenicity, often luteal cysts, which are physiological in nature. There are also ovarian flavinized cysts, often associated with trophoblastic tumors and also with ovarian hyperstimulation, which usually require treatment of the primary disease, or surgery if acute abdomen occurs. Ovarian chocolate cysts can cause dysmenorrhea and affect conception, and ovarian edema and hydrocele are often confused with ovarian cysts. Therefore, ovarian cysts are very variable and should not be treated in the same way. Ovarian cysts can be single- or multi-roomed, and can vary in size. The largest growing tumor in the body is an ovarian cyst, usually a mucinous cystadenoma of the ovary, which can fill the entire abdomen. Usually ovarian cysts >6-7 cm should be operated on, why? It can be twisted at the tip, necrosis and infection. The possibility of malignancy should also be noted. Ovarian cysts can be physiologic or pathologic and must be treated carefully and the decision to operate should never be taken lightly.
