Teratomas are not normal fetuses; they are a type of tumor originating from germ cells in the ovaries. Pregnancy will not affect the normal development of the baby, and regular prenatal check-ups at the hospital are advisable. If it is possible to surgically remove the teratoma before trying to conceive, it is best to do so. Teratomas can be benign or malignant. Benign teratomas contain various components, including skin, hair, teeth, and bones. Malignant teratomas are poorly differentiated and more prone to malignant transformations and metastasis.

Malignant manifestations of ovarian teratoma

When ovarian teratomas are small, they usually do not exhibit any clinical symptoms. When teratomas become malignant, they grow faster, and if too large, may cause women to experience abdominal distension and pain. The pulling of surrounding tissues can also lead to pain in the lower abdomen on one side in women. When ovarian teratomas are severely malignant, they can invade or compress surrounding tissues, leading to related symptoms like compression of the fallopian tubes, causing infertility; or compression towards the bladder, causing frequent and urgent urination in women. The texture of teratomas is uneven. In certain special circumstances, such as when a woman suddenly changes her position, torsion or rupture of the teratoma can occur, causing acute lower abdominal pain and other symptoms of acute abdomen. Additionally, in the late stages of the disease, symptoms such as emaciation and anemia can also appear.

Is surgery necessary for ovarian teratoma?

If a color Doppler ultrasound confirms the presence of an ovarian teratoma, surgical treatment is required, as ovarian teratomas can be benign or malignant. Once diagnosed via color Doppler ultrasound, abdominal CT, MRI, or other radiological methods, surgery is necessary. Based on the surgical pathology results, if the teratoma is benign, cystectomy can be performed. If the pathology indicates malignancy, a more extensive surgical procedure and postoperative chemotherapy may be required. During this period, it is important to avoid ovarian cyst torsion and rupture to prevent the necessity of emergency surgery for acute abdomen. Ovarian teratomas cannot disappear naturally, so prompt surgical treatment is essential once diagnosed.

Does teratoma affect menstruation?

Teratoma, under normal circumstances, does not affect menstruation, but it does affect fertility. If it is confirmed that one side has a teratoma, surgery is generally required. After treatment, the ovary on that side is typically removed. Once removed, that ovary will no longer ovulate, and ovulation must occur from the other ovary. The maintenance of hormone levels in the body needs to be supported by the other ovary. If the function of the other ovary is normal, menstruation will continue to occur normally; it will not affect menstruation. However, if after the removal of the teratoma, one ovary is removed, the chance of conception is reduced by half compared to others. Therefore, it is crucial for patients with teratoma to undergo surgery as early as possible. After the surgery, if the pathology shows no issues and if it is a simple teratoma removal, it does not affect menstruation.

Can teratoma be treated with minimally invasive surgery?

Teratoma is a type of ovarian cyst. Whether a teratoma can be treated through minimally invasive surgery needs to be assessed based on the size of the teratoma. If the teratoma is of normal size, then it can be treated with laparoscopic teratoma surgery. However, if the teratoma is excessively large, such a large teratoma will occupy most of the volume of the pelvic abdomen. In this case, it is not possible to perform minimally invasive surgery. Therefore, further evaluation is needed before performing teratoma surgery to determine if it is suitable for minimally invasive 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.
