The identical sunny weather conditions that draws a lot of travelers and new citizens to the sun-belt also will increase the risk of skin cancer. The consequences of continual sunlight exposure outcome in superficial sunshine spots which can be noticeable as well as invisible changes that occur beneath the skin's surface area. Ultraviolet images and photodynamic therapy (PDT) are two latest developments that should assist in the early detection and treatment of each types of pre-cancerous skin lesions.

Early Detection with UV Photography Ultraviolet (UV) photography gives an extremely helpful screening device to help the competent physician detect sun damaged skin that will not be noticeable on a regimen

The most typical therapy choices for AKs have typically involved topical ointment 5-FU (Effudex), laser resurfacing, or chemical peels. To prevent the prolonged restoration period of time and possible scarring connected using these strategies, photodynamic therapy continues to be produced.

Photodynamic therapy (PDT) is the remedy of option to the invisible deeper sun injury along with the noticeable pre-cancerous AK lesions. PDT involves a two phase method which has been verified successful in medical screening. This remedy cleared 100% from the AKs in 2/3 of the individuals right after one therapy.

The first step is the application of a topical answer called Levulan. Abnormal cells possess a a lot better affinity for the solution and take in it while the wholesome cells do not. The answer is remaining on for an incubation period of time long lasting anywhere from quarter-hour to 18 hours.

The 2nd stage of PDT is to apply a concentrated mild source to activate the chemical reaction which destroys the irregular cells.
