Metvix Photodynamic Therapy (PDT) is a medical procedure designed to treat pre-cancerous and cancerous skin lesions. The treatment involves the application of Metvix, a topical cream containing methyl aminolevulinate, which makes skin cells more sensitive to light. After the cream is applied to the affected areas, the skin is exposed to a special light that activates the cream, selectively targeting and destroying abnormal cells, while leaving healthy skin mostly unaffected.
Health Canada has approved Metvix PDT for treating superficial basal cell carcinoma and actinic keratoses, common conditions caused by sun damage. By using light and topical agents to target only the abnormal cells, this treatment offers a more localized, less invasive option compared to traditional ablative and surgical methods.
Why Choose Metvix Photodynamic Therapy?
- Effective Skin Cancer Prevention: Metvix PDT effectively treats pre-cancerous cells, reducing the risk of developing skin cancer.
- Non-Invasive: No surgery or cuts are required, making it a safer and less painful option for treating skin lesions.
- Minimal Downtime: Unlike surgical procedures, Metvix PDT typically requires only short recovery times and minimal disruption to your daily routine.
- Targeted Treatment: The cream selectively targets abnormal cells, leaving surrounding healthy skin untouched.
Conditions Treated with Metvix PDT
- Actinic Keratoses (AKs): These rough, scaly patches are caused by sun damage and can potentially develop into skin cancer.
- Superficial Basal Cell Carcinoma: A common, low-risk form of skin cancer that affects the surface of the skin.
What to Expect Before, During, and After Treatment
Pre-Treatment Preparation:
- Health History: Be sure to complete your health history and intake form before your appointment. Notify your provider about any allergies (particularly to nuts) or if you have a history of cold sores.
- Avoid Sun Exposure: It’s important to avoid UV exposure for two weeks prior to treatment. This will reduce the risk of complications and ensure the cream’s effectiveness.
- Protective Clothing: After treatment, you’ll need protective clothing (wide-brimmed hats, sunglasses) to shield your skin from the sun.
During Treatment:
- The targeted skin lesions are gently prepped by scraping away any crusted or scaly tissue, making the treatment more effective.
- The Metvix cream is applied, then left on the skin for 2.5 to 3 hours before the light exposure.
- Light therapy is used to activate the cream, which selectively destroys the abnormal cells.
Post-Treatment Care:
- Common Side Effects: Redness, swelling, peeling, and flaking may occur. Blistering can also happen in some cases.
- Sun Protection: Avoid sun exposure for at least 48 hours post-treatment. Apply a broad-spectrum sunscreen (SPF 30+) daily to prevent any further sun damage.
- Avoid Heat and Exfoliants: For 7-10 days after treatment, avoid hot tubs, saunas, and exfoliating skincare products.
How Many Treatments Are Needed?
Most patients require 1-3 treatments, spaced about 1-6 months apart. The exact number of sessions depends on the severity of the condition. Follow-up treatments may be necessary to ensure any new or recurring sun damage is addressed.
