Many ovarian cysts are asymptomatic, generally detected during physical examinations or gynecological assessments, sometimes palpable as masses. An ultrasound can confirm the diagnosis by assessing the size of the mass near the adnexa, as well as the location and characteristics of the cyst. Often after an ultrasound, it may also be necessary to check for ovarian tumor markers. This is because ultrasound may reveal mixed masses that could potentially be malignant. If tumor markers are normal, not elevated, the likelihood of malignancy is low. If an ovarian cyst is discovered, regular check-ups are necessary, typically involving ultrasound examinations as many individuals display no obvious symptoms.

How to treat ovarian cysts?

The majority of ovarian cysts are physiological. If an ovarian cyst is detected for the first time during an ultrasound, it can be observed temporarily. Generally, such cysts will gradually shrink or disappear naturally after two to three months. If the cyst is relatively large, exceeding 5cm, and the ovary has not shrunk after two to three months of observation, but instead the cyst has grown, it is likely an ovarian tumor, which requires surgical treatment. If an ovarian tumor occurs, there is a potential for malignancy or torsion, so timely surgical intervention is necessary.

Are ovarian cysts serious?

Ovarian tissue is very complex in composition. It is the site with the most types of primary tumors among all body organs. Different types of ovarian tumors exhibit significant differences in histological structure and biological behavior. Benign ovarian tumors are typically small, often asymptomatic, and are usually discovered incidentally during gynecological examinations. As cysts grow, one may experience abdominal bloating or feel a mass in the abdomen. During examination, abdominal distention can be observed, the mass is usually mobile, percussion shows a dull sound, and there is no shifting dullness. If the tumor is malignant, there are often no symptoms in the early stages; later stages mainly present with symptoms of abdominal bloating, abdominal masses, and gastrointestinal symptoms. If adhesions occur with surrounding tissues, symptoms of compression, such as abdominal pain, back pain, and leg pain may also appear. Therefore, ovarian tumors should be treated promptly once detected.

Do ovarian cysts hurt?

This ovarian cyst is generally a benign tumor change. Normally, ovarian cysts do not show any symptoms. However, as the cyst grows larger, it may cause an increase in abdominal size and bloating. It may also press on the gastrointestinal tract and the bladder, leading to corresponding urinary and gastrointestinal symptoms. Additionally, changes in body position may lead to acute abdomen, such as ovarian cysts, torsion of the stalk, rupture of ovarian cysts, and other conditions.

malignant symptoms of ovarian cysts

Malignant ovarian cysts, commonly known as ovarian cancer, often present with no symptoms in most people. Patients generally do not exhibit any specific symptoms. In advanced stages, however, symptoms such as ascites and abdominal swelling or pain may occur due to the cyst pressing on other organs in the abdomen. Initially, these symptoms might be mistaken for gastrointestinal issues, hence the importance of undergoing a gynecological ultrasound examination. In early stages, ovarian tumors may not show any symptoms, so it is recommended that women undergo tumor marker tests, such as CA125 and HE4, as well as routine ultrasound examinations.

Causes of ovarian cysts

There are several common causes of ovarian cysts. The first is during the ovulation process where the follicle fails to release an egg, resulting in the formation of follicular cysts. The ultrasound typically shows these as simple cysts containing follicular fluid. Another situation is the corpus luteum cyst, which occurs after ovulation when the ovary forms a wound surface and a corpus luteum. Cysts can also develop during the growth of the corpus luteum. These two types of cysts generally disappear after the next menstrual period and are considered physiological cysts that usually require no treatment. However, some cysts result from pathological changes in ovarian cells, or even from tumors. On an ultrasound, these appear differently, often as mixed composition masses, in which case surgical treatment is recommended.
