To minimize the damage on nails and cuticles when patients with cancer are treated with cytostatic, physicians sometimes use cryotherapy. The patient has on cold gloves during the treatment, which lasts about one hour. This treatment has been used for 15 years and the aim is to prevent blood flow in the small blood vessels and thereby prevent the medicine to affect that area. The research is not conclusive but the clinical experience shows fewer cases of damage to fingers and reduced risk of loss of fingernails.
