Colon cancer treatment with ablation

Radiofrequency ablation for colon cancer is one of the effective treatment options without incisions. That is an intense tumor heating by exposure to high-frequency radio waves. Colon cancer lesions are heated from 80 to 110°C. As a result, the tumor dies, and its burned tissue slowly resolves. Modern equipment allows doctors to accurately dose the effect on the tumor and direct the waves with high accuracy so as not to damage healthy tissue. The procedure is performed under local anesthesia. Then, sedatives and an anesthetic are injected into the patient at the place where the probes are placed. Under ultrasound control, electrodes are inserted into the tumor tissue through the skin, a high-frequency current (450-500 kilohertz) is applied to them, and the probes emit radio waves. Under their influence, colon tumor cells heat up and die. At the same time, the surrounding healthy tissues are not injured. The whole procedure takes from 10 to 30 minutes. In the future, scar tissue forms at the site of the tumor. To monitor the changes, the patient must undergo regular examinations. Oncologists expect colon cancer to shrink to complete tumor elimination, which can sometimes be equal to surgery.
