A five-centimeter cyst is generally not serious if there are no other uncomfortable symptoms; it is more serious if there are severe pressure symptoms or complications such as infection or bleeding. Uterine cysts can be categorized into congenital cysts and acquired cysts. Uterine cysts are rare benign lesions that are usually asymptomatic and not serious when they are small. If the cyst is large, five centimeters or more, it may produce compression symptoms. For example, pressure on the bladder can cause frequent urination, urgency, or difficulty urinating. Symptoms are also more severe when the pressure is heavy. If a five-centimeter cyst becomes infected or bleeds internally, abdominal pain may occur. It is more serious when it often causes discomfort to the patient. When serious complications arise from a five-centimeter cyst, it is recommended that the patient go to the hospital in a timely manner, and surgery can be performed to remove the cyst.
