wards and clinics


Most liver of tumors are inoperable and require the use of other methods for treatment. Another non-surgical treatment method for the ablation of these tumors is the microwave technique. 
In addition, microwave can be used as a complementary therapy in liver tumor surgery, general chemotherapy, and radiotherapy. 


This is the tumor tissue ablation technique using microwaves in the body. In fact, it is similar to home microwave ovens used for warming and cooking food and passes the same energy to tumors through a special antenna inserted into the lesion. 

How microwave is performed 

In this method, special antennas (microwave needles) will be inserted into the tumor guided by CT scan. Then, the living cancerous cells in the site will be ablated by connecting to the microwave generator and creating heating. 

Priority of microwave over surgery 

In the case where number of lesions in the liver is limited (less than 5 lesions) and they are small (less than 7cm), this surgery can achieve good results. 

Duration of surgery 

Depending of the number of lesions, this surgery takes almost 1 to 2 hours. After the operation, the patient will be controlled for 2 to 4 hours and, then, he/she will be discharged. 

Anesthesia during the surgery 

This surgery requires anesthesia because these tumors will be ablated with microwave at the temperature above 100ºC, and this temperature is intolerable. So, anesthesia is required. 

Preparations for the surgery

Patients should be fasting about 4 to 6 hours before the surgery. 
Having one companion is necessary for doing the patients works. 
Having the patients medical records (CT scan, MRI, and liver and blood coagulation tests) is necessary. 
Taking shower and shaving the abdominal region is necessary. 

The necessary examinations before the surgery 

Your liver function should be examined by the doctor at this clinic. 
If you have heart disease or diabetes, make sure to notify the doctor so that the necessary measures would be taken. 
Before the surgery, it is necessary to run the required tests for blood coagulation. 
 If you are taking medicines such as Aspirin, Warfarin, and Plevix, make sure to keep your doctor informed. 

The possibility of tumor recurrence after the surgery 

Tumor ablation does not mean the complete disappearance of the lesion and complete treatment because cancer cells may survive on tumor margins, leading to tumor recurrence. Thus, the patient will be examined in the next controls and, in case of recurrence, the tumor will be ablated again. 

Post-operative hospitalization

This surgery is usually performed in an outpatient basis and the patient will be discharged in 2 to 4 hours. Depending on the patients condition, he/she may require hospitalization for 24 hours, which will be performed if necessary. 

Post-operative bed rest 

After this surgery, you will feel weakness, lethargy, anorexia, fever and, in some cases, pain in the shoulder area. These symptoms may last for 10 days. So, you will need to take rest for 7 to 10 days. 

Evaluation of surgery results 

If there is no particular problem,
 you should attend the clinic 3 months after the surgery for check-up and the next control. 

Can liver tumors be destroyed is a single session using the microwave surgery? 

The number of sessions will be determined according to the number and size of the liver tumors because, in each session, only 2 to 3 lesions can be ablated using the microwave technique. 

Microwave impact in preventing the tumor growth 

It depends on the patients admission time. If the size and number of lesions at the admission time are not excessive, surgery results will be desirable and highly effective in controlling the disease. 

The Advantages of The Microwave Technique

Substitution for surgery 
Lack of possibility to perform surgery for various reasons 
Reduction of tumor size to help chemotherapy or radiotherapy 
Liver relief in cases where the tumor has caused 
Fewer invasions to the patients body, resulting in fewer side effects 
Helping the patients with tumor involvement in both lobes of the liver that cannot be operated 
Repeatability of the surgery in the event of tumor recurrence of cancer cells remaining in the tumor margin
Removing the central parts of the tumor, while these parts do not respond well to radiotherapy 
Short recovery time compared with other methods 
Rapid recovery of the patient and the possibility of beginning chemotherapy immediately after the surgery 
No incision on the skin
