What is the chance that my actinic keratoses will recur?
While PDT is a very effective treatment, there is a reasonable chance that you may continue to need periodic treatments for actinic keratoses, depending on your individual skin, severity of prior sun damage, and your compulsion to avoid the sun. Often there are layers of underlying sun damage from prior years that rise to the surface over time.
Actinic keratoses may recur or a new cancer may develop in the same or adjacent area even after photodynamic therapy or other treatments. Some skin actinic keratoses are more aggressive than others and need additional treatment and closer follow-up.
Sun-damaged skin frequently needs additional follow-up and possible further treatment, at least annual rechecks and further PDT treatments are advised. Several studies have shown that photodynamic therapy tends to have a cure rate comparable to the traditional treatment with fluorouracil (Carac, Efudex, Fluoroplex).

Follow-up appointments with your dermatologist or physician are very important, especially in the first few years after photodynamic therapy. Many patients are seen every four to six months after their diagnosis of actinic keratoses of the skin.
Self-skin examinations monthly are good practice for patients with a history of skin cancer. Any changing or new growth should be promptly checked by your physician. More regular follow-up appointments may be needed for those with more aggressive tumors or tumors in high-risk areas. Your physician will recommend the proper follow-up for your specific condition.
