Treatment of Liver Tumors with Microwave Therapy
Treatment of liver tumors
Most liver tumors are inoperable and require alternative treatment methods. One of the non-surgical techniques for eliminating these tumors is the microwave ablation technique.
Moreover, microwave technology can be utilized as an adjunctive treatment in the surgical management of liver masses, as well as in general chemotherapy and radiotherapy.
Microwave
The technique involves destroying tumor tissue using microwave energy within the body. Essentially, it operates similarly to household microwave ovens, which are used to heat and cook food. The same type of energy is delivered to the tumor through specialized antennas that are placed within the lesion.
The Superiority of Microwave Therapy Over Surgery
In cases where the liver lesions are limited (fewer than 5 lesions) and small in size (less than 7 centimeters), this procedure yields favorable outcomes.
Advantages of the Microwave Technique
– Surgical Alternative
– Inability to perform surgery due to various reasons
– Reducing tumor size to assist with chemotherapy or radiotherapy.
Relieving pain in the liver area in cases where tumor involvement has caused discomfort.
Less invasive to the patient’s body, resulting in fewer complications.
Assisting patients with tumors affecting both liver lobes where surgery is not feasible.
The procedure can be repeated in cases of tumor recurrence or if cancerous cells remain at the tumor margins.
Eliminating the central parts of the tumor, as these areas do not respond well to radiotherapy.
Shorter recovery period compared to other methods.
– Rapid recovery of the patient and the possibility of initiating chemotherapy immediately after surgery.
– No surgical incision is made on the surface of the skin.

Frequently Asked Questions
How does a microwave treat a tumor?
The microwave technique involves destroying tumor tissue using microwave energy. The energy is delivered to the tumor through specialized antennas that are inserted into the lesion, effectively burning the cancerous cells at the site.
How is the procedure performed?
Specialized antennas are guided into the tumor using a CT scan and are connected to a microwave generator to produce sufficient heat, effectively destroying the living cancer cells.
How long does the procedure take?
Considering the number of lesions, the procedure takes approximately 1 to 2 hours, and the patient is discharged under observation after 2 to 4 hours.
Is anesthesia necessary?
Yes, the procedure is performed at temperatures exceeding 100 degrees Celsius, which is intolerable for the patient; therefore, anesthesia is required.
What are the necessary preparations before the procedure?
- Fasting for 4 to 6 hours prior to the procedure.
- Having someone accompany the patient to assist with their affairs.
- Carrying all medical documents (CT, MRI, liver tests, and blood coagulation tests).
- Bathing and removing unwanted hair from the abdominal area
What does preoperative examination include?
- Evaluation of liver function by the physician
- Notification in case of underlying conditions or diabetes
- Performing the necessary tests for blood coagulation.
- Inform your doctor if you are taking medications such as aspirin, warfarin, or Plavix.
Is there a possibility of tumor recurrence?
Yes, cancer cells may survive at the tumor margins and lead to recurrence. If necessary, the procedure will be performed again.
How long is the recovery period after the surgery?
Symptoms such as weakness, loss of appetite, fever, and pain in the shoulder area may persist for up to 10 days and require 7 to 10 days of rest.
When should we return for a follow-up to review the results of the procedure?
If there are no specific complications, the patient should return for a check-up and evaluation of the results three months after the procedure.
How many treatment sessions are necessary?
The number of sessions is determined based on the quantity and size of the tumors. In each session, it is possible to ablate up to two lesions using the microwave technique.
What is the effect of microwaves in preventing tumor growth?
The outcomes of the procedure depend on the timing of the patient’s visit; if the size and number of lesions are appropriate, it can have a significant impact on disease control.
How can the surgery appointment be scheduled?
By visiting the pardis noor Interventional Clinic and consulting with a specialist in interventional procedures, you can schedule your surgery appointment.
