Photodynamic Therapy for the Treatment of Light Skin Cancer Precursors
Photodynamic Therapy in Berlin Steglitz
Photodynamic therapy (PDT) is an innovative and highly effective method for treating light skin cancer precursors, particularly actinic keratoses. These precursors develop due to prolonged UV exposure and, if left untreated, can lead to skin cancer. The therapy combines a light-activated substance with a special light source to selectively destroy abnormal skin cells without damaging healthy tissue.
Procedure of Photodynamic Therapy
The photodynamic therapy procedure consists of several steps:
1. Application of the Photosensitizer:
A light-sensitive substance, usually 5-Aminolevulinic Acid (ALA), is applied to the affected skin area.
2. Incubation Period
The photosensitizer penetrates the skin and accumulates in the abnormal cells. The incubation time varies depending on the severity of the skin changes, usually between 1 and 4 hours.
3. Illumination
After the incubation period, the skin is irradiated with a special light source—usually blue or red light—which activates the substance to produce reactive oxygen species that destroy the abnormal cells.
Advantages of Photodynamic Therapy
-
Non-invasive: PDT requires no surgical procedures and leaves minimal scarring.
-
Targeted Treatment: Only abnormal cells are destroyed, leaving healthy tissue unharmed.
-
Cosmetically Advantageous: The skin regenerates quickly and the aesthetic outcome is generally excellent.
-
Wide Range of Applications: In addition to actinic keratoses, other superficial skin cancers can be treated.
FAQs - Frequently Asked Questions about Photodynamic Therapy
How long does the treatment take?
The entire procedure usually takes several hours, including the incubation period and illumination.
Is the treatment painful?
During the illumination, a slight burning or stinging sensation may occur, which is generally well tolerated.
What does the skin look like after the treatment?
The treated skin is often red and may peel or flake for a few days to weeks, similar to a sunburn.
Results and Aftercare
After treatment with photodynamic therapy, initial improvements are often noticeable within a few days. Complete healing of the treated areas typically takes one to two weeks. It is important to protect the skin from direct sunlight during this period to avoid irritation and support healing. Repeated treatments may be necessary, especially for patients with extensive sun damage.
