Sonodynamic therapy (SDT)

Whathappens during PDT

PDT is carried out in two stages.

1) Preparation

First, you'll need to come into the hospital or clinic to be given the light-sensitive medication.
Depending on the area of the body being treated, the medication may be a cream, injection or special drink.
Once the medication has been applied or given, you may be asked to go home and return in a few hours or days this will give the medication a chance to build-up in the abnormal cells.

2) Light treatment

Later, you'll need to return to the hospital or clinic for the light treatment.
This will involve a lamp or laser being shone onto the treatment area for around 10-45 minutes.
To treat abnormal cells inside your body, such as in your lungs, an endoscope (flexible tube) will be passed into your body to deliver the light.
Sometimes alocal anaesthetic may be used to numb the treatment area or you may be given medication to help you relax during the procedure.
