Brief Summary
This study aims to examine whether the pain of topical photodynamic therapy (PDT) is significantly different when using low irradiance ambulatory light emitting diode (LED) devices compared with conventional higher irradiance hospital based LED light sources when used for superficial non-melanoma skin cancer. The investigators are also investigating the phototoxicity and efficacy of each regime in this randomized assessor-blinded clinical trial.

Conditions
Outcome Measures
Primary Outcomes (1)
Pain on VAS Score
assess on visual analogue scale (VAS) score of 0 - 10cm, with 0 representing no pain experienced through to 10 representing the worst pain imaginable. The participant marks across a 0-10cm unmarked line where their level of pain experience is and this is measured eg. 2cm if experiencing mild pain or 8.5cm which would represent severe pain
one week after treatment
Secondary Outcomes (3)
Phototoxicity
one week after treatment
Clinical Clearance of Lesion
12 months after treatment
Patient Satisfaction
one year after treatment - last visit
Study Arms (2)
low irradiance LED PDT
ACTIVE COMPARATORAmbulight LED portable PDT treatment
conventional higher irradiance LED
ACTIVE COMPARATORConventional LED hospital based standard PDT treatment
Interventions
battery-operated low irradiance red light LED ("skin cancer plaster")
Eligibility Criteria
You may qualify if:
- Bowen's disease or superficial basal cell carcinoma referred for PDT and lesion not greater than 2.4cm diameter
You may not qualify if:
- Unable to give consent, \>2cm diameter, lesions on highly curved surfaces where ambulatory device would not adhere
