Ovarian cyst is one of the common gynecological diseases, which is actually a kind of ovarian tumor. In clinical practice, patients often encounter situations where they see the word “cyst” written on the test results and think that their tumor is benign and that they don’t need to undergo surgery. In fact, this idea is very wrong. In fact, there is a difference between benign and malignant ovarian cysts. Malignant ovarian masses have a very poor prognosis if they are not treated in a timely manner. Because early ovarian cysts have very mild (or even no) symptoms, they are difficult to detect by the patients themselves. Therefore, gynecologic examination is the only way to detect ovarian cysts early. It is recommended that gynecologic examinations should be performed at least once a year for women over 30 years of age. As ovarian cysts gradually increase in size, various symptoms will slowly manifest themselves in the patient. If the cyst is slightly enlarged, some patients may have digestive symptoms, such as enlarged abdomen, bloating and indigestion; if the cyst increases more, the patient may have pressure symptoms such as hydronephrosis, dry stools, or changes in mood and libido; when the cyst is malignant, the patient may have poor appetite, wasting and weakness. Therefore, once these symptoms appear, patients must pay attention to them and go to regular hospitals for relevant examinations in time. First of all, pelvic examination should be performed to see if there is ascites, pelvic masses, etc. Then further ultrasound diagnosis should be done. Then further ultrasound diagnosis will be done. If abnormalities are found in the ovaries, a CA-125 (tumor marker test) must be done to clarify the diagnosis. There is no specific medicine in the treatment of either benign cysts or malignant tumors, and surgical treatment is necessary. For cysts considered benign, both open surgery and laparoscopic surgery can be performed. Comparing these two methods, laparoscopic surgery has the advantages of less trauma, shorter hospital stay and faster recovery. However, patients with severe systemic complications and older age (80 years or more) should be cautious. However, patients with suspected malignancy should try not to choose laparoscopic surgery.
