Many women are found to have ovarian cysts, which are also tumors that grow on top of the ovaries, during gynecological checkups. The symptoms of ovarian cysts are multifaceted, such as pain on both sides of the abdomen, incomplete menstruation, lumps in the abdomen, lumbosacral distension and a series of other clinical symptoms. Of course, there are also some ovarian cysts that may not have any symptoms. Ovarian cysts are divided into physiological cysts and pathological cysts. Physiological ovarian cysts are usually formed when follicles mature and continue to grow due to a variety of reasons that they are not expelled from the body in time. However, if the cyst reaches 5-10 cm in size, it may compress the adjacent tissues and cause abdominal distension and pain. Pathological ovarian cysts commonly include malignant tumors, teratomas, chocolate cysts, etc. Pathological ovarian cysts may show many clinical symptoms when the disease has progressed to a certain point, such as irregular vaginal bleeding, excessive menstrual flow, prolonged menstrual periods, severe pain in the abdomen, and lumbosacral distension. Of course, not all ovarian cysts with symptoms are malignant, but further examination is needed to confirm the diagnosis. If a woman has the above symptoms, she needs to go to the hospital for ultrasound, CT or MRI to confirm the diagnosis to rule out the possibility of ovarian cysts. After the diagnosis is made, treatment is prompt and regular follow-up is needed.
