Teratoma is a type of ovarian cyst, and whether surgery is necessary depends on the specific conditions found during examination. Teratomas are related to congenital factors. It has been found that medication is ineffective in treating teratomas. If the teratoma is relatively small, regular check-ups can be sufficient. However, if it is growing rapidly, there is a possibility of malignant transformation, or if it is large enough to cause abdominal pain due to torsion, then surgery must be prepared for immediately. Ultimately, the nature of the teratoma is determined through pathological examination.

Can teratoma affect pregnancy?

Teratoma is a relatively common disease that occurs in the ovaries of women, caused by abnormal differentiation of reproductive cells during the embryonic period. Teratomas are classified into benign and malignant types. Teratomas can indeed affect a woman's ability to become pregnant and can pose a threat to health. Potential complications include torsion, rupture, and infection of the teratoma, which can gradually lead to other concurrent conditions. If not treated promptly, it could cause acute diseases and threaten a woman's ability to reproduce, affecting the happiness of the entire family. When an ovarian teratoma enlarges or undergoes degeneration, it may prevent the normal movement of eggs or fertilized eggs, thereby affecting normal fertility. Upon detection of a teratoma, surgery is generally required for treatment.

Ovarian teratoma is what?

Ovarian teratoma, which is one of several types of ovarian cysts, is mostly benign. However, in clinical practice, there is a possibility for some ovarian teratomas to become malignant. Therefore, it is recommended that if ovarian teratoma is suspected, immediate examinations should be conducted at local hospitals to assess the condition. If necessary, it is advised that patients with ovarian teratoma undergo surgical removal of the tumor in the hospital.

Can teratoma be treated with medication?

Teratomas are divided into mature and immature teratomas. Mature teratomas, also known as dermoid cysts, are benign tumors, commonly found in individuals aged 20-40, usually unilaterally. The contents of the cyst typically include substances like sebum, hair, and teeth. Immature teratomas, on the other hand, are malignant tumors, though less common. They have a higher rate of recurrence and metastasis. Surgical treatment is generally recommended for teratomas, while medical treatment is not advised. Less frequently, laparoscopic surgery can be used for certain teratomas. If a teratoma is suspected to be malignant preoperatively, exploratory laparotomy is often performed. Postoperative outcomes are generally better for benign mature teratomas. In cases of malignant teratomas, chemotherapy may be required after surgery.

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.

Is surgery necessary for a teratoma?

Once the presence of a teratoma is considered, surgical treatment is recommended. Surgery serves two purposes: first, to remove ovarian cysts for disease treatment; and second, the removed ovarian cysts require routine postoperative pathology to confirm the diagnosis of ovarian teratoma. Without a pathological diagnosis, it cannot be definitively diagnosed as an ovarian teratoma; the diagnosis must be supported by pathological results.
