Using imaging guided techniques (Ultrasound, CT or MRI), cryo-probes are inserted into tumors to lower the temperature of the targerted area -160℃ or below. Later the temperature is raised to 20-40℃. This is repeated two or three times to lead to complete ablation of the whole tumor
CSA has the following advantages: - It is applicable to both small and large tumors. It can lead to ablation of a single tumor or several tumors - Cryosurgical ablation will not cause damage to large blood vessels and trachea hence can be used to treat tumors at the nearby area - Cryosurgical ablation will not cause any pain. Instead it helps to reduce pain - The whole process of cryosurgical ablation can be monitored through imaging techniques such as ultrasound - After cancerous cells have been destroyed by CSA, they are left intact. Dead cancerous cells will release antigens which will stimulate the immune system to eradicate any remaining cancerous cells and reduce re-occurrence of cancer
