Your doctor may have explained to you that you have a tumor in your liver, kidney or elsewhere. There are a number of different treatment options that may be available to you, including open surgery, minimally invasive surgery, ablation or chemotherapy.  Your doctor will help you decide which treatment is most suitable for you, based on your individual case. 

If your doctor has proposed ablation therapy, you may be interested to learn about CAScination technology and how it may help to improve your treatment outcome.



Ablation is a minimally invasive procedure that is performed in a CT suite that, unlike open surgery, requires only a small puncture to the skin.   There are different kinds of ablation, including radiofrequency ablation, microwave ablation or laser ablation.   During these procedures, a fine needle is passed through your skin into the organ and tumor and then a high temperature is applied, which destroys the cancer cells.  The procedure usually takes around 2 hours and you can go home the day after the treatment.



  • Since ablation therapy targets the tumor directly, it is important that the placement of the ablation needle is very accurate to ensure complete destruction of the tumor.  Sometimes this can be tricky depending on the tumor’s location and size.  With the CAS-One system your doctor can check that the whole tumor has been cleared from your organ after the procedure by using ‘before and after’ imaging techniques.
  • Sometimes tumors can be difficult to target by surgery or ablation if, for example, they are near a major artery.  As ablation therapy with CAScination's CAS-One technology is very precise, it may enable your doctor to treat a tumor that would be very difficult to reach with conventional methods.
  • With CAS-One IR the total procedure time is usually shorter than conventional ablation therapy.  This  means you may spend less time under general anaesthesia which can lead to a shorter recovery time so you can go home sooner.
  • All interventional radiology procedures will lead to some exposure to radiation. The technology that CAScination's CAS-One IR uses to monitor you during the procedure while you are under general anaesthesia is different to conventional therapy and exposes you to lower radiation levels than conventional ablation (Beyer et al, 2016).
