Ovarian cysts can vary in size, ranging from a few millimeters to several centimeters in diameter. However, the size of an ovarian cyst that is considered dangerous or requires medical attention depends on several factors, including the type of cyst, symptoms, and the age of the patient. Here are some general guidelines:
-
Functional cysts: These cysts are the most common type and usually resolve on their own. Cysts of less than 4 cm are considered small and do not usually cause symptoms. Cysts of 4-5 cm are usually monitored and may require follow-up imaging. Cysts larger than 5 cm are considered big and may be harmful.
-
Endometriomas: These cysts are associated with endometriosis and can cause pain and discomfort. Cysts larger than 4 cm in diameter have a greater chance of causing complications such as rupture or ovarian torsion.
-
Dermoid cysts: These cysts are usually benign but can grow quite large. Dermoid cysts larger than 3 cm are usually removed surgically.
In general, surgery is not recommended for ovarian cysts unless they are larger than 50 to 60 millimeters (mm) (about 2 to 2.4 inches) in size. However, this guideline can vary depending on the type of cyst, symptoms, and age of the patient. It is important to consult a gynecologist if you experience any symptoms or have concerns about the size of your ovarian cyst.
