Call the office or schedule an appointment online to learn more about PDT treatment options.


What is PDT?

PDT is a two-part therapy for pre-cancers (also common as actinic keratosis) that includes both drugs and light therapy. This type of therapy can be highly effective for precancerous growths. Because it’s far less invasive than other options, PDT is often a common treatment.


How does PDT therapy work?

In this type of treatment, your Bopp Dermatology & Facial Plastic Surgery doctor applies a cream containing a photosensitizing agent. 

You’ll typically wait for several hours to allow full drug absorption. Then, your doctor directs a specific type of light on the treatment area. You’ll wear protective goggles throughout the treatment.

You may experience some mild stinging as the light triggers drug reaction, but this should cease shortly after treatment.

The resulting reaction destroys pre-cancerous cells.


What does PDT treat?

There are three main applications for PDT:

  • Basal cell cancers in the upper skin 
  • Actinic keratosis, a precancerous skin growth
  • Bowen's disease, a very early form of squamous cell carcinoma

It's often the preferred therapy because it's noninvasive, causes little to no scarring, and can treat even large areas. 


What happens after PDT treatment?

You'll be extra-sensitive to sunlight after treatment, so be sure to follow all skin protection instructions from your Bopp Dermatology & Facial Plastic Surgery doctor closely. It is recommended that you stay out of the sun and birght light for 40 hours. Your skin will be sensitive to the sun and you could get serverly sunburned.

Depending on how well you respond to treatment and how deep the cancerous growths were, you might need additional treatment sessions about one month apart.

Every case of skin cancer is unique, so the experienced dermatologists at Bopp Dermatology & Facial Plastic Surgery create customized treatment plans just for you. To find out whether you need PDT or another skin cancer treatment, book an appointment online or by phone today.
