Teratoma is not a pregnancy; it is a type of ovarian tumor. Most of the time, this tumor is benign. It commonly occurs in individuals aged between 20 and 40 years. The formation of teratomas is generally due to poor differentiation during the embryonic stage, resulting in the development of this type of tumor. Very occasionally, teratomas can become malignant, which requires high vigilance. Most cases of malignancy are seen in young females aged between 11 and 19. Malignant teratomas are usually solid, but they can also have cystic areas.

Will a teratoma disappear with Chinese herbal medicine?

Teratoma is a common type of ovarian cyst. Clinically, teratomas will not disappear by taking traditional Chinese medicine. Generally, it is recommended that if a patient suspects a teratoma, they should immediately seek medical attention at a local hospital, undergo gynecological examinations, gynecological ultrasound, and other relevant tests, and hospitalization for surgical treatment if necessary. The primary purpose of the surgery is to completely remove the ovarian teratoma. Secondly, the removed ovarian teratoma should be subjected to further pathological examination to confirm whether it is an ovarian teratoma.

Are ovarian teratomas congenital?

Ovarian teratomas are congenital, primarily deriving from primordial germ cells. Teratomas consist of tissues from multiple embryonic layers, mostly being immature types. Most ovarian teratomas are cystic. Depending on the degree of tissue differentiation, teratomas can be classified as benign or malignant. Benign teratomas, also known as mature teratomas, are more common in women aged 20-40 and are usually unilateral and either round or ovoid in shape. A portion of these teratomas are malignant, typically found in younger patients, roughly aged 11-19 years, and this condition has a poorer prognosis, requiring timely surgical treatment.

How large must an ovarian teratoma be to require surgery?

Ovarian teratomas, if detected by ultrasound, are indicative of surgery regardless of the size of the tumor. However, it is essential to locate the lesion accurately to proceed with the surgery. For teratomas smaller than two centimeters, it can be quite challenging to find the lesion, which might lead to surgical failure. Additionally, this can increase the trauma for the patient and the costs of surgery. Thus, it is generally advised to perform surgery on teratomas that are larger than two centimeters to ensure a more reliable outcome. In cases where patients have other diseases in conjunction with a teratoma, it is also feasible to consider removing the teratoma during surgery for the other conditions, always attempting to thoroughly explore and locate the teratoma regardless of its size.

Ovarian teratoma grows during pregnancy

Will ovarian dermoid cysts grow larger after pregnancy? According to clinical experience, there is no correlation between ovarian dermoid cysts and pregnancy status. If there was a dermoid cyst before pregnancy, it is sufficient to monitor its changes during pregnancy check-ups. Generally, ovarian dermoid cysts do not grow larger after pregnancy. However, it is important to note that ovarian dermoid cysts are prone to torsion and rupture. Therefore, patients with ovarian dermoid cysts should be attentive to any abdominal pain during pregnancy. If there is no abdominal pain, generally there should not be a major issue.

Does teratoma affect the fetus?

Teratoma is a common benign ovarian tumor in women, and most teratomas do not affect the fetus. Since the majority of teratomas are smaller than 5cm, even under the stimulation of pregnancy, teratomas generally do not grow significantly large, and it is generally considered that small teratomas do not affect the fetus. However, if the teratoma is very large, more than 8cm, there is a risk of rupture and infection during pregnancy, which could potentially affect the fetus. For large teratomas during pregnancy, enhanced monitoring is necessary to avoid rupture and infection, in order to protect the fetus.
