What is tumor radiofrequency ablation therapy? Radiofrequency ablation therapy for tumor is the most advanced and minimally invasive tumor treatment method that uses radiofrequency thermal effect to cause coagulative necrosis of tissues under the guidance of imaging (CT, MRI, B ultrasound, etc.) to achieve the purpose of destroying tumor. The principle of radiofrequency ablation? Human tissue structure and body fluids contain a large number of dielectrics, such as ions, water, protein molecules, etc. These particles can move under the action of electric field. Radio frequency is a kind of high frequency vibration that reaches 150,000 times per second. Under the action of high-frequency alternating current, the ions between the RF ablation electrodes move rapidly in the direction of the power lines and produce high-frequency oscillations. Due to the different size, mass, charge and movement speed of various ions, the ions rub against each other and produce thermal effect, so that the local tissue temperature can reach 80-100℃. Due to the poor heat dissipation ability of tumor tissues, the local temperature of tumor tissues is higher than that of its neighboring normal tissues. Which tumors are suitable for radiofrequency ablation treatment? Radiofrequency ablation can be used for the treatment of benign and malignant solid tumors in many organs of human body. At present, it is more clinically used for liver cancer, lung cancer, breast cancer and soft tissue sarcoma. It is especially suitable for those advanced tumors that cannot tolerate surgery or cannot be removed surgically, which can achieve the purpose of reducing tumor load, improving patients’ quality of life and prolonging survival. What is the procedure of radiofrequency ablation? Radiofrequency ablation treatment can be performed under general anesthesia or local anesthesia according to the patient’s condition, and the treatment time is usually about 1-2 hours. Patients can listen to music and watch TV while receiving tumor ablation treatment, which has a high safety factor. Compared with traditional tumor treatment methods, it is less traumatic, less painful, has less impact on the body, and has faster recovery after surgery.
