DAYLIGHT PHOTODYNAMIC THERAPY IN LONDON
Photodynamic Therapy (PTD) is a simple, non-invasive procedure that can be used to treat precancerous skin lesions. The treatment uses topical cream and light therapy to destroy cancerous and precancerous cells but doesn’t affect healthy tissue. Traditional photodynamic therapy uses artificial light as the light source, but this treatment can also take the form of daylight photodynamic therapy where natural sunlight is used.
This treatment is effective in treating non-melanoma skin cancers including Basal cell carcinoma (BCC) and Squamous cell carcinoma (SCC), as well as precancerous lesions such as Actinic Keratosis and Bowen’s disease.
HOW DOES DAYLIGHT PHOTODYNAMIC THERAPY WORK?
The treatment works by applying a topical cream, which is light sensitive, to the lesion and then using a light source, artificial or natural, to destroy any abnormal cells. On their own, both the cream and the light are harmless, but when exposed to light the cream causes a reaction that damages nearby cells.
During your procedure, sunscreen of an SPF of 30 or higher will be applied to the treatment area, which protects your skin. Your lesion is then prepared by cleaning the surrounding skin and removing any crusting. The topical cream will then be applied and will be left to fully absorb and build up in the abnormal cells. The light treatment will then begin which is either administered through a lamp or a laser for a short time, or you will be exposed to the daylight for a couple of hours.
The main side effect of the treatment is that you may experience mild tingling or pain in the treated area. This can be reduced by the use of a water spray to soothe any feelings of discomfort.
FREQUENTLY ASKED QUESTIONS
The only difference between these two treatments is the light source that is used. In Photodynamic Therapy, an artificial light in the form of a lamp or a laser is used. In Daylight Photodynamic Therapy, the light source is natural daylight.
Most people can carry on with normal activities 24-48 hours after treatment. The key thing is to avoid direct sunlight during this time as you may be more sensitive to light. You will gradually become less sensitive to light and things will return to normal.
It is recommended that you cover up on your way home from the treatment to avoid sunlight as much as possible. If the treatment is on your face, it is a good idea to bring a hat, scarf or sunglasses. If the treatment is on your body, wear clothes which will cover any exposed skin.
