What are the dangers of teratomas?

Hello Doctor: Today I went to the gynecology clinic for an examination and found that I have a teratoma about 5 cm in size on my right ovary.
The doctor said it appears to be benign at the moment, but he recommended laparoscopic surgery to remove it due to a 10% chance of it becoming malignant.
I would like to ask how high the risks are for this teratoma removal surgery? Also, since my menstrual period may be approaching, would it be better to wait until after my period to have the surgery? Thank you for your response.
Sincerely, Ally.

Hello Ms.
Ally: Teratomas are the most common type of ovarian germ cell tumors, accounting for about 30% of all primary ovarian tumors.
Teratomas are classified as benign tumors, with a malignancy rate of less than 2%, and more than three-quarters of malignant transformations occur in individuals over 40 years of age.
In adolescent girls, more than half of ovarian tumors are teratomas.
Although there is a 15% chance of teratomas causing ovarian torsion, leading to pain or abdominal discomfort, most teratomas do not present any noticeable symptoms.
The vast majority of cases are discovered incidentally during routine ultrasound examinations.
Surgical treatment is necessary.
For women hoping to conceive, teratomas should be carefully and completely excised while preserving normal ovarian tissue.
Notably, there is a 15-25% chance of teratomas occurring in the contralateral ovary.
During surgery, the physician will carefully examine the contralateral ovary but will not perform an incision on the ovary to avoid damaging normal ovarian tissue.
The timing of the surgery should be scheduled to avoid the menstrual period, as slight anemia and general weakness during menstruation can increase the risk of infection and potentially slow recovery.
Wishing you all the best! Dr.

More Info

Dear Ally,
Thank you for your inquiry regarding the risks associated with teratoma surgery. Teratomas are germ cell tumors that can contain various types of tissue, including hair, muscle, and even teeth. While many teratomas are benign, the potential for malignancy, as you mentioned, is a valid concern, especially in cases where the tumor is larger than 5 cm.

Risks of Teratoma Surgery
1. Surgical Risks: As with any surgical procedure, there are inherent risks involved. These can include:
- Infection: Post-operative infections can occur, which may require additional treatment.

- Bleeding: There is a risk of excessive bleeding during or after the surgery.

- Damage to Surrounding Organs: The ovaries and surrounding structures are delicate, and there is a risk of unintentional damage during the procedure.

- Anesthesia Risks: General anesthesia carries its own risks, including respiratory complications and allergic reactions.

2. Specific Risks Related to Teratoma:
- If the teratoma is indeed malignant, there may be additional considerations regarding the extent of surgery required and the need for further treatment, such as chemotherapy.

- The size of the teratoma (5 cm in your case) is significant, as larger tumors have a higher likelihood of complications during removal.

3. Recovery Considerations: Post-operative recovery can vary. Some patients may experience pain and discomfort, while others may recover quickly. It is essential to follow your surgeon's post-operative care instructions to minimize complications.

Timing of Surgery
Regarding the timing of the surgery in relation to your menstrual cycle, it is generally advisable to schedule surgery when you are not on your period. This is because menstruation can complicate the surgical procedure, potentially increasing the risk of bleeding and making the surgical field less clear. Additionally, hormonal fluctuations during your menstrual cycle can affect your overall comfort and recovery.

Recommendations
1. Consultation with Your Surgeon: It is crucial to have a detailed discussion with your surgeon about the risks and benefits of the procedure. They can provide you with personalized information based on your medical history and the specifics of your teratoma.

2. Consider a Second Opinion: If you have concerns about the surgery or the diagnosis, seeking a second opinion from another gynecologist or a specialist in oncology may provide you with additional insights and peace of mind.

3. Pre-operative Preparation: Ensure that you are well-prepared for the surgery. This includes discussing any medications you are taking, your medical history, and any allergies you may have with your healthcare provider.

4. Post-operative Care: Plan for your recovery after surgery. Arrange for someone to help you at home, as you may need assistance during the initial recovery period.

In conclusion, while the surgery to remove a teratoma is generally safe, it is essential to weigh the risks and benefits carefully. Discussing your concerns with your healthcare provider will help you make an informed decision. Remember, early intervention can often lead to better outcomes, especially in cases where there is a risk of malignancy.

Best wishes for your health and recovery.

Sincerely,

Sarcoma is primarily treated with complete surgical resection. The prognosis is related to the degree of malignancy and whether it can be completely excised. If the patient's overall condition permits, surgery is still recommended. Biopsy is not suitable for sarcoma.
