What are the different types of cancer ablation?

Therapy of cancer ablation is a minimally invasive procedure that involves inserting a needle into a cancer tumor and injection of gas, energy waves or chemicals directly into the tumor. Changes in hot or cold temperatures caused by these factors destroy the tumor and undesirable tumor cells eventually turn into a scar. Cancer ablation is recommended for people who are not good candidates for chemotherapy or surgery. Available four main types of cancer ablation are radiofrequency ablation (RFA), microwave ablation, cryoablation and ethanol instillations. During the procedure, the patient is under light seating through intravenous (IV) solution. Then the physician uses ultrasound or computer tomography (CT) to indicate the precise placement of the tumor. The radio waves are sent to the tumor through the needle inserted into the skin and the heat is produced from the vibration of tumor molecules and killing tumor cells. Usually there are no complications and most people return to their normal daily activities the day after treatment.

microwave ablation is the latest procedure developed in the treatment of thermal cancer ablation. It can be used to treat some adrenal, bones, liver and lung cancer. The initial treatment process is the same as RFA, except for much stronger microwave energy is sent by a needle to a tumor. The microwave causes the water molecules inside the tumor to move rapidly, causing the tumor temperature to increase, resulting in destruction of cancer cells. People who receive microwave ablation are usually able to go home the next day.

Cryoablation is most commonly used for patients with kidney or bone cancer. If the patient is a good candidate that depends on the exact location of the tumor, the procedure of Cryoablation can help maintain most of the kidneys or bones in the destruction of cancer cells. During the procedure, the compressed nitrogen is sent by opening the needle and to the tumor. Gas turns into microscopic pieces of ice and zamRZNE cancer cells he encounters, causing the tumor to shrink and die. Most patients can safely return home next day.

liver tumors are treated with some success of the instillation of percutaneous ethanol. The method of percutaneous ethanol requires ethanol injection into the tumor. Ethanol alcohol reduces the temperature of the tumor cell and destroys the membrane of the external cells, causing the tumor to die rapidly. This cancer ablation may cause unconsciousness, respiratory problems or seizures in some patients, and is usually the last method of thermal ablation selected for treatment.
