Skin Cancer Post-Operative Scar Evaluation Using Autofluorescence Features

In this work post-operative skin cancer scar evaluation with LED screening device has been described. The wavelength used for inducing autofluorescence (AF) of chromophores in the skin is 405nm. The green channel of the captured images is the best to calculate AF intensity ratio from the scar and the surrounding skin of 10 patients with healthy healing and scars with cancer recurrence. This non-invasive multispectral screening method can help dermato-oncologist to make a decision on evaluating if the scar is healing correctly and evaluate any pigmentation that could be suspected as a recurrent cancer.
