Tumor Ablation/Cancer Treatment

Tumor Ablation/Cancer Treatment

This is a minimally invasive surgical method to treat solid cancers. Special probes are used to “burn” or “freeze” cancers without the usual surgery. Computed Tomography (CT), Ultrasound (US) or Magnetic Resonance Imaging (MRI) is used to guide and position the needle probe into the tumor. This requires only a tiny hole, usually less than 3 mm via which the probe is introduced. When the probe is within the cancer it is attached to a generator which “burns” or “freezes” the cancer.

How well does it work?

The effectiveness of this new technique in treating cancer depends on two things:

  1. The size of the tumor
  2. Its accessibility to the probes

In general, for cancers 3 cm or less and easily accessible percutaneously the aim is to completely kill the cancer. The larger the tumor the more difficult it is to achieve compete cancer death, therefore early treatment is crucial.

Which tumors can be treated this way?

The most common cancers treated by this method are lung cancer, liver cancer and kidney (renal) cancer. Other cancers can also be treated provided they are accessible and of appropriate size.
