Electrocautery is a less invasive and modern way of operating. It replaces scalpels/knives in some cases and can be used for a wide range of operations (such as removing a cyst, tumour or wart).
Procedures with the electrode result in less pain, less bleeding and less swelling compared to normal knife surgery. Electrocautery requires less time and therefore your animal needs to be under anaesthesia for less time. It also reduces the risk of post-operative infections and other discomforts.
