Recent advances in treatment of non melanoma skin cancer

Abstract

Actinic (Solar) Keratoses now considered by many authorities to represent a superficial squamous cell carcinoma, 2. Bowen's disease, 3. Basal cell carcinoma, 4. Squamous cell carcinoma. A world wide epidemic of tsunami proportions of NMSC continues, in part due to the: aging of the world's population; • increased frequency of early childhood sunburns; increased exposure to UV light; • fashion trends (arsenic has made something of a comeback being found repeatedly in some alternative medicine preparations from 3rd world countries but now also available in the West); increased leisure, sun-holidays; depletion of ozone layer; and, more recently, immunosuppression (eg. medication following organ transplant and AIDS). Squamous cell carcinoma has increased 30%, whilst Basal cell carcinoma have increased 75% over 10 years in South Wales. It is also likely that similar increases have occurred in other parts throughout the Western world.
