Patients with teratomas are advised to undergo surgery as soon as possible. It is impossible for teratomas to be treated with medication or be absorbed naturally. Teratomas also have a tendency to become malignant, so once diagnosed, it is recommended to have surgery as soon as possible. After the surgery, it is essential to send the removed teratoma tissue for pathological examination to check for any issues. The majority of teratomas are generally non-problematic, but a very few may show malignant tendencies. Therefore, it is advised that patients with teratomas undergo surgery early, followed by postoperative anti-inflammatory symptomatic treatment. Otherwise, if the surgery is not performed, the presence of a teratoma can cause ovulatory disorders. Furthermore, if a teratoma grows too large, it can cause lower abdominal pain and discomfort. Thus, patients with teratomas can only be treated symptomatically through surgery.

Can a teratoma be detected by ultrasound?

Teratomas are a common type of solid tumor in the ovaries, and the vast majority of ovarian teratomas are benign. The most common method to examine teratomas in women is to perform an ultrasound. Generally, an abdominal ultrasound can be done 3-7 days after the menstrual cycle has ended to observe the ultrasonic echo of both ovaries. Normally, both ovaries are uniform in size and echo. If the ultrasound suggests the presence of a substantive mass on the ovary, which has a strong echo, or indicates the presence of fat or bone echoes, then this condition is highly suspected to be a teratoma. For ovarian teratomas, if the size is relatively small and there are no clinical symptoms, temporary observation is possible. However, if it is larger than five centimeters, laparoscopic removal is generally recommended.

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.

Does ovarian teratoma affect pregnancy?

In gynecology, teratomas are a very common type of ovarian cyst. If a teratoma is discovered during the pre-pregnancy period, its size should be considered. If the teratoma is larger than five centimeters in diameter and is accompanied by abnormalities on a CT scan, it is recommended to undergo surgery before attempting to conceive. If the teratoma is very small, such as two to three centimeters in diameter, it does not affect future pregnancy. If a teratoma is discovered during early pregnancy, opinions vary. Some recommend surgical treatment after the first trimester, while others suggest a pregnancy observation plan. Teratomas during pregnancy are prone to complications such as ovarian cyst torsion, which can cause abdominal pain. Therefore, if you have a teratoma and successfully conceive, be mindful of any pain.

Is the recurrence of ovarian teratoma serious?

If there is a recurrence after undergoing ovarian teratoma surgery, it is considered serious. In such cases, it should be considered that the ovarian teratoma might be malignant, and malignant teratomas can potentially metastasize. Therefore, it is recommended that women, after having ovarian teratoma surgery, should actively pursue further radiotherapy and chemotherapy based on the nature of the teratoma, to control the cancer cells. In daily life, it is advisable to eat a light diet, consume various fresh vegetables and fruits, and avoid cold, spicy, and irritating foods. Moderate exercise should be performed to enhance physical condition and maintain a cheerful mood, all of which can help alleviate the condition.

What to do about ovarian teratoma abdominal pain?

If a patient has an ovarian teratoma and also has abdominal pain, they should immediately visit a local hospital for a gynecological examination and a gynecological ultrasound. The main purpose is to confirm whether there is torsion of the ovarian teratoma. Once torsion of the ovarian teratoma occurs, it can cause ischemic necrosis of the ipsilateral fallopian tube and ovary, leading to severe consequences. Therefore, once an ovarian teratoma is detected, it is not advisable for the patient to continue observation treatment. Prompt surgery is key to avoiding pathological changes and complications.
