Ovarian teratomas can cause abdominal pain and might even result in sudden abdominal enlargement, often accompanied by symptoms like bloating. Women experiencing these symptoms are advised to seek medical attention promptly. Ovarian teratomas are more commonly found in younger women, particularly during their reproductive years. Thus, female patients experiencing these symptoms should promptly undergo an ultrasound at a hospital to check for the presence of teratomas and also have a blood test for tumor markers. If a teratoma is present, it is recommended to undergo surgical treatment as soon as possible due to the risk of malignant transformation.

Can ovarian teratomas become cancerous?

Most ovarian teratomas are a type of benign tumor on the ovaries, but a few may become malignant. Therefore, if an ultrasound suggests an ovarian teratoma and it is relatively small, around two to three centimeters, without any symptoms, we can temporarily observe it. However, the condition is that we should test for tumor markers, such as checking if there are significant increases in CA-125 or AFP, to see if there's a tendency for malignancy. Another condition is that regular follow-up examinations are essential. If there's a sudden increase in size in a short period or a continuous growth, it is advisable to consider surgical treatment, as early surgical intervention tends to have better outcomes.

Can teratomas recur?

Teratomas can recur clinically, but the recurrence rate is relatively low. There are cases of ovarian teratoma recurrence after teratoma excision surgery. For recurrent teratomas after surgery, it is still recommended to undergo surgical removal again. With an increase in the number of surgeries, the probability of teratoma recurrence gradually decreases. It is recommended that patients who have undergone teratoma surgery undergo regular follow-up examinations.

What are the symptoms of teratoma recurrence?

If a teratoma recurs, in cases of benign teratomas, generally there are no symptoms. Symptoms only arise when the tumor grows large enough to compress the bladder and intestines, which might induce signs of bladder and rectal irritation. Additionally, a teratoma might undergo torsion due to changes in body position, causing sudden lower abdominal pain. If it is a malignant teratoma, there might not be noticeable symptoms early on. The recurrence of a teratoma can only be detected through regular monitoring with ultrasound and tumor markers; there are no better methods available.

The difference between ovarian teratoma and cysts

Ovarian teratomas and ovarian cysts are two completely different diseases. Ovarian teratomas are caused by congenital factors and are tumors of the germ cells that can be benign or malignant, usually requiring surgical removal for treatment. Ovarian cysts, on the other hand, are caused by various factors in women, such as poor lifestyle habits or an imperfect diet structure, leading to a hormonal disease. Ovarian cysts can be physiological or pathological. Usually, physiological ovarian cysts gradually disappear with the menstrual cycle, while pathological ovarian cysts can also be benign or malignant. The need for surgical treatment depends on the nature, size, and clinical symptoms of the ovarian cyst.

Are teratomas mostly benign?

Ovarian teratomas belong to the category of germ cell tumors, which are divided into mature teratomas and immature teratomas. Immature teratomas are malignant and account for 1%-3% of ovarian teratomas, thus they occur relatively less frequently. These are more commonly found in young patients, with an average age of 11-19 years. Mature teratomas, also known as dermoid cysts, are benign and can account for 10%-20% of ovarian tumors and 85%-97% of germ cell tumors, comprising over 95% of ovarian teratomas. These can occur at any age, but are most common between 20-40 years, often unilateral, and may contain components such as fats, hair, and sometimes teeth and bone tissues. Thus, the majority of mature teratomas are benign tumors.
