Cryoablation is a medical procedure that uses extreme cold to destroy abnormal tissues, such as tumors. By applying a cryogenic substance, like liquid nitrogen, doctors can freeze the targeted area, causing the cells to die. This technique is often used in treating certain types of cancer, as well as other conditions like arrhythmias. The procedure is minimally invasive, meaning it usually requires only small incisions or can even be done through a thin tube inserted into the body. Patients often experience less pain and quicker recovery times compared to traditional surgery, making cryoablation an appealing option for many.
