1, What Is Cryotherapy?
Cryotherapy is a medical technique both ancient and modern. As early as thousands of years ago, ice was used to treat infected wounds and various knife injuries. Ar-He knife, a kind of cryotherapy, is the first technique employing space rocket guidance technology in the world and the only technique with efficacies of ultra-low temperature and thermotherapy. Ar-He knife is a precise apparatus approved by the U.S. FDA for accurately targeting and killing cancer cells.
2, Treatment Procedures of Cryotherapy
It is the most common approach to percutaneously insert freezing needle into tumor and infuse Argon to cause rapid drop in temperature inside tumor and then switch to Helium to heat the ice ball under ultrasound or CT guidance. The procedures of cooling and heating alternate at least 2 cycles. Freezing is supposed not to be suspended until ice ball covers the whole tumor and its surrounding tissue 5 to 10 mm in thickness. Multiple freezing needles should be employed for big tumors. Sometimes, two to three procedures are required when necessary.

Dressing is applied to minimally invasive incision after cryotherapy finishes. Patients are allowed to go back to their ward for rests.
3, Benefits of Taking Cryotherapy
(1) High achievement ratio, few complications
(2) Surgery-free, mild bleeding and minimally invasive
(3) Physical therapy with low rates of side effects
(4) It can be applied to almost all kinds of solid tumors.
(5) It can be performed alone or in conjunction with chemotherapy and radiotherapy or surgery.
(6) Remarkable therapeutic effects, easily operated, cost-effective and patient-friendly
(7) Anti-recurrence: tumor recurrence is often detected after surgery. However, residual tumor after surgery does not tend to grow rapidly in a short time after cryoablation therapy
