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 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.

How to Determine if a Teratoma is Benign

Teratomas in women are classified into benign and malignant categories. Benign teratomas typically have a complete capsule and grow very slowly. Some women find that the size of the teratoma does not change significantly during follow-up exams. Malignant teratomas, however, grow quickly and can present severe clinical symptoms, such as abdominal pain, bloating, and pelvic masses, with some women also experiencing fluid accumulation in the abdominal cavity. Furthermore, blood tests for gynecological tumor markers can also be used for differentiation. For example, in malignant tumors, markers such as CA-125, CA-199, and alpha-fetoprotein are elevated to varying degrees, particularly alpha-fetoprotein. During a CT scan, malignant teratomas may show unclear borders, potentially indicating invasion into the surrounding tissues. Additionally, after surgical removal of the tumor, pathological histological examination can be conducted for further differentiation. For instance, malignant teratomas tend to have a higher proportion of immature components.

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.

Can ovarian teratomas be treated with Chinese medicine?

Ovarian teratomas cannot be treated with traditional Chinese medicine. Firstly, ovarian teratomas are categorized as germ cell tumors and are divided into mature and immature teratomas. Mature teratomas, also known as dermoid cysts, are benign tumors. The cysts may contain hair, teeth, and some bony material. Immature teratomas, on the other hand, are malignant tumors that make up 1% to 3% of ovarian teratomas and are more common in younger patients aged 11 to 19 years. Therefore, once an ovarian teratoma is suspected, it is necessary to promptly visit a hospital for further examinations to determine the nature of the cyst, and then, based on the examination results, appropriately handle it with timely surgical intervention.

Is teratoma related to HPV?

Teratomas are not related to HPV. Teratomas grow on the ovaries, while HPV infections occur in the cervix or vaginal area, so the locations of these two diseases are different. There are benign teratomas and immature teratomas, which must be surgically removed after detection. Most women will be infected with the HPV virus at some point in their lives, and the majority will clear the virus within two years through their immune system, so there is no need to be overly concerned about HPV infections, just regular follow-ups are sufficient.
