Abstract
Cryosurgery involves local freezing of tissues for the controlled destruction or removal, by using various cryogens like Nitrous oxide (-750C), Carbon- dioxide snow (-790C) and liquid Nitrogen (-1960C). The cryogens produce their action through (1) heat transfer, (2) cell injury, and (3) inflammation. The clinical applications of the technique include treatment of equine sarcoids, prostate, angiomas, bovine eye squamous cell carcinoma, oopherectomy in bitches, feline cutaneous squamous cell carcinoma, disbudding in calves. Cryosurgery is also used to treat a number of skin conditions like warts, moles, skin tags, solar keratoses, and small skin cancers. The technique requires minimal post operative care. Conditions such as skin discomfort, burning sensation of skin and hypopigmentation are some the complications of the technique. Cryosurgery is contraindicated in animals with history of conditions such as melanoma, compromised circulation, cold intolerance and cold utricaria. Advantages of cryotherapy are ease of use, low cost, good cosmetic results and minimal surgical complications.

Key words: Cancer, Cryosurgery, Liquid Nitrogen,
