Photodynamic therapy (PDT) is an advanced, non-invasive treatment option for certain types of skin cancer. At Clear Skin Dermatology in Toronto, Ontario, we offer PDT to help patients manage superficial skin cancers effectively. If you’re considering PDT, here are answers to some frequently asked questions that will help you understand how the treatment works and its benefits.
Photodynamic therapy is a treatment that combines light with a photosensitizing agent to treat skin cancer. The agent, applied topically to the affected area, makes skin cells sensitive to light. After a while, the area is exposed to a specific light wavelength that activates the agent, destroying cancerous cells. PDT is commonly used for superficial basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and precancerous conditions like actinic keratosis.
During the treatment, a topical photosensitizing medication is applied to the skin. The drug is absorbed by cancerous or precancerous cells. After a set waiting period, a special light activates the medication, releasing oxygen that destroys the targeted cancer cells. The procedure is usually completed in one or two sessions, depending on the severity of the condition.
PDT is generally well-tolerated. While some patients experience mild discomfort, such as a stinging or burning sensation during the light treatment, it typically lasts only a few minutes. After the session, the treated area may appear red or inflamed, similar to a mild sunburn, but these side effects usually resolve within a few hours to a few days.
PDT has several key advantages:
Recovery from PDT is typically 1-2 weeks. Most patients experience redness, swelling, or crusting in the treated area, which usually resolves within a few days. Following aftercare instructions is essential, including avoiding direct sunlight and using gentle skincare products during healing. Full recovery and results can take a few weeks, but many patients begin seeing improvements within a month.
PDT is highly effective for treating superficial basal cell carcinoma, squamous cell carcinoma, and actinic keratosis. The success of the treatment depends on factors such as the type and size of the skin cancer. Your dermatologist will assess your case and determine whether PDT is the right option.
