The physical examination revealed a teratoma issue, which is generally related to congenital factors and has no relation to our regular diet. However, once a teratoma is found, it is essential to avoid eating cold and raw foods, as cold stimuli can also cause smooth muscle spasms, leading to discomfort in the abdomen. Regarding teratomas, the main consideration is the specific size of the tumor and the series conditions of the tumor. Some teratomas may undergo torsion, and others may become overly large or malignant, necessitating timely surgical intervention.

Post-operative care for teratoma surgery

Patients who have undergone teratoma surgery should be aware of the following clinical considerations. Firstly, postoperative patients should be carefully managed in terms of diet. If the teratoma is located in the abdomen, food should be restricted until intestinal function is restored, starting from liquids to semi-liquids and eventually solid foods. Secondly, if the teratoma is malignant, regular follow-up exams are necessary after surgery to monitor any changes in the condition. Thirdly, it’s important to monitor the color and amount of fluid in the drainage tube, as well as changes in the patient's body temperature, heart rate, pulse, and blood pressure after surgery to promptly detect and address any complications.

Why do benign teratomas recur?

Benign teratomas, although not aggressive or metastatic, do not require adjuvant chemotherapy or radiation therapy after curative surgery to fight the tumor. However, many benign teratomas recur after surgery and require further surgical treatment. The cause of benign teratoma recurrence is considered to be due to the persistent presence of oncogenic factors. Therefore, benign tumors can also recur, since the exact cause and pathogenesis of benign teratomas are still unclear clinically. Thus, prevention from an etiological perspective is not possible, and the only option is timely surgical removal upon tumor detection to prevent the benign teratoma from becoming malignant. For patients with benign teratomas, regular follow-up is necessary after curative surgery to monitor any changes in the condition. If signs of recurrence are detected, prompt intervention is necessary to prevent malignancy.

Is a teratoma pregnancy?

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.

Is the likelihood of a teratoma being benign high?

Currently, teratomas are relatively common in clinical practice, and there is a high probability that teratomas are benign, with most teratomas being benign. The definitive diagnosis requires surgical removal of the teratoma, followed by routine pathological examination post-surgery. The nature of the teratoma, whether benign or malignant, is determined based on the pathological examination, and the results of the pathology dictate the next steps in the treatment plan. If the teratoma is malignant, further follow-up treatment is necessary.

Can a teratoma disappear with medication?

Ovarian teratomas cannot be treated with medication. Ovarian teratomas are the most common type of germ cell tumor and are categorized into mature and immature teratomas. Mature teratomas, also known as dermoid cysts, are mostly benign tumors. These cysts generally have a single chamber filled with sebum and hair, and sometimes teeth and bone material can also be found inside. On the other hand, immature teratomas are malignant tumors, making up 1%-3% of ovarian teratomas, commonly seen in younger patients with an average age between 11 and 19 years. Thus, it is crucial to seek prompt medical evaluation upon detection of an ovarian teratoma to determine the size of the cyst and, if necessary, pursue surgical treatment, as medication will not resolve the issue.
