Adnexal cysts are one of the common benign gynecological conditions, usually caused by abnormalities in the ovaries or fallopian tubes. This cyst measures 3.5×2.3 cm and is considered to be of moderate size. Generally speaking, cysts smaller than 5 cm are often physiological cysts, possibly caused by failure of the follicle to rupture, and these cysts typically resolve spontaneously within two months. Such cysts are not considered serious. However, when a cyst exceeds 5 cm in size or presents with continuous growth, pain, irregular bleeding, or other symptoms, further examination and treatment may be necessary.

A cyst measuring 3.5×2.3 cm falls into the moderate size category. If there are no obvious symptoms, doctors may recommend close observation and an ultrasound examination every 3 to 6 months to assess any changes in the cyst. It is also important to maintain healthy lifestyle habits, including quitting smoking, limiting alcohol consumption, eating a balanced diet, and engaging in moderate exercise, to maintain hormonal balance. If the cyst shows signs of growth or if symptoms such as acute abdominal pain or fever occur, prompt medical attention is advised, and surgical removal of the cyst may be necessary.
