Photodynamic Therapy

How does Metvix PDT work?

Metvix PDT uses a different approach to treatment of these lesions in comparison to conventional treatments. It is a simple non-invasive treatment that consists of the application of Metvix cream to the lesion(s) followed by its exposure to light from the specifically designed Aktilite lamp. The cells in the lesion absorb the active ingredient from the Metvix cream. When exposed to the red light from the Alkilite lamp, a chemical reaction occurs which destroys the lesion, minimising side effects and the potential for scarring. In addition to its superior efficacy, PDT has a better aesthetic outcome than other treatments for certain skin cancers and actinic keratosis. During the light therapy you will be required to wear protective eyewear. You can have more than one skin cancer treated at a time. PDT has minimal downtime and less discomfort than invasive procedures.

​

Research shows the advantages of PDT include:

• Minimal damage to healthy tissue

• Less invasive than surgery

• Precise targeting of cancer cells

• Ability to repeat treatments to the same site

• Less scarring

What can I expect?

​

You may experience a burning or stinging sensation during light application. Local discomfort at the treatment site varies between people and locations on the body. It is usually mild but can be uncomfortable in some people. If pain is experienced, in most people it is short term and seldom lasts for hours or days. Paracetamol is advisable prior to light application. Swelling may persist for up to one week, and redness for up to two weeks. Depending on the type and number of lesions you have, you may need a further treatment. This will be explained in your appointment.
