Microwave Ablation/Radio-Frequency Ablation

Microwave Ablation/Radio-Frequency Ablation


Microwave ablation (MWA) and radiofrequency ablation (RFA) are minimally invasive procedures that use heat to destroy tumors. MWA uses microwaves to generate heat, while RFA uses radiofrequency waves. Both procedures are performed under sedation or general anesthesia.

In MWA, a probe is inserted into the tumor and microwaves are generated. The microwaves cause the water molecules in the tumor to vibrate, which produces heat. The heat destroys the tumor cells.

In RFA, a needle is inserted into the tumor and radiofrequency waves are generated. The radiofrequency waves cause the tissue to heat up, which destroys the tumor cells.

MWA and RFA are used to treat a variety of tumors, including:

  • Liver tumors
  • Kidney tumors
  • Lung tumors
  • Bone tumors
  • Soft tissue tumors

MWA and RFA are also used to treat tumors that are not cancerous, such as:

  • Benign liver tumors
  • Benign kidney tumors
  • Benign bone tumors
  • Benign soft tissue tumors

MWA and RFA are safe and effective procedures. They have a short recovery time and are associated with a low risk of complications.

The risks of MWA and RFA include:

  • Pain
  • Bleeding
  • Infection
  • Scarring
  • Damage to the surrounding tissues

In most cases, the benefits of MWA and RFA outweigh the risks. The procedures are a safe and effective way to treat tumors.

Here are the steps involved in microwave ablation and radiofrequency ablation:

  1. The patient is given sedation or general anesthesia.
  2. A probe or needle is inserted into the tumor.
  3. Microwaves or radiofrequency waves are generated.
  4. The heat destroys the tumor cells.
  5. The probe or needle is removed.

The patient will usually be able to go home the same day after microwave ablation or radiofrequency ablation. The procedure is usually successful in destroying the tumor, but there is a small risk of recurrence.
