When suffering from ovarian teratomas, it is necessary to undergo surgical removal as soon as possible. For women with fertility needs, it is generally possible to plan for pregnancy three months after the surgery. Ovarian teratomas are mostly benign, and the body can usually recover quickly after the surgery, approximately 2-3 months later, at which point the ovaries generally resume normal ovulatory function. It is recommended that women undergo regular follow-ups at the hospital after the surgical removal, as there is a possibility of recurrence of teratomas. Moreover, it is advisable to schedule intercourse based on the ovulation status.

Is surgery necessary for teratoma?

Ovarian teratoma belongs to a type of germ cell tumor. Ovarian teratomas can be classified into mature teratomas and immature teratomas. Mature teratoma, also known as dermoid cyst, is mostly a benign tumor. Within the cyst, components such as sebum, hair, teeth, and bone can be found. Additionally, mature teratomas have a malignant transformation risk of 2%-4% and are commonly seen in postmenopausal women. On the other hand, immature teratomas are malignant tumors, accounting for 1%-3% of ovarian teratomas and more commonly found in younger patients, with the average age ranging from 11 to 19 years old. Therefore, timely surgical treatment is necessary once an ovarian teratoma is detected.

What department should I go to for a teratoma?

Teratomas are not considered complex and difficult diseases; you can just register for a regular gynecology appointment. Then, related examinations such as ultrasound scans are necessary to assess aspects like the size and echoes of the teratoma, the presence of ascites in the pelvic cavity, whether there are adhesions nearby, and the clarity of the boundaries. Corresponding gynecological examinations are also required, as well as checking for symptoms such as compression of adjacent tissues and the presence of significant abdominal pain. Generally, teratomas around five centimeters in size may experience torsion of the pedicle, so laparoscopic surgery might be necessary when required.

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.

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.

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.
