Percutaneous Ethanol (Alcohol) Injection

A liquid containing a high concentration of alcohol is then injected through the needle. The concentrated alcohol destroys whatever cells it comes in contact with. Alcohol injection is most effective with small tumors (less than 3 centimeters). In some instances, several small tumors can be treated simultansouly.
