How big is an ovarian cyst to be malignant?

Uterine and ovarian tumors are common tumors of the female reproductive organs with various characteristics and shapes, namely unilateral or bilateral, cystic or solid, benign or malignant, among which cystic is the most common, with a certain proportion of malignancy. Next, let’s discuss how likely ovarian cysts are to become malignant. Hope the ladies can understand this.

The size of an ovarian cyst is not the key to whether it is benign or malignant. A very large one may be benign, and a small one may be malignant. Generally, if ultrasound shows that the mass is cystic or solid, accompanied by an increase in tumor markers, the possibility of malignancy is relatively high. If it is a purely cystic mass, especially one with thin walls and good sound permeability, the possibility of malignancy is low.

The probability of ovarian cyst becoming malignant is not high, generally no more than 10%. Ovarian cyst is a benign disease, but it has many complications, such as rupture, distortion, deterioration, bleeding, etc., which are all its complications.

However, its progression rate is very low. Small ovarian cysts need to be observed regularly and followed up with B-ultrasound every six months to a year. Ovarian cysts larger than 5 centimeters need to be treated surgically. In this way, it may be better for women's bodies. In addition, in daily life, we must pay attention to regular gynecological examinations and gynecological B-ultrasound examinations for women.

Surgical treatment: The treatment of uterine and ovarian cysts depends on the patient's age, whether it is malignant, the location, volume, size, growth rate of the cyst, whether the fertility function is preserved, and the patient's subjective wishes.

1. Surgical treatment of benign ovarian cysts

(1) Ovarian cystectomy. Young patients, especially premenopausal patients, often choose this type of surgery, and try to preserve all normal uterine and ovarian tissues.

(2) Bilateral salpingo-oophorectomy: For very old patients (over 45 years old) or postmenopausal patients, unilateral or bilateral salpingo-oophorectomy can be performed.

2. Surgical treatment of malignant ovarian cysts

(1) Most patients are in the terminal stage when they seek medical treatment, so every effort should be made to remove the primary cyst and any visible pelvic and abdominal metastatic lesions.

(2) Consider leaving a flexible tube in the abdomen to facilitate the injection of chemotherapy drugs after surgery.
