Is there a way to easily detect basal cell carcinoma in its early stages?

High index of : Suspicion. Early examination of non-healing ulcers. Pearly nodules, nodules that bleed easily, nodules with dilated blood vessels around them, by biopsy. See this site for more information. http://www.ncbi.nlm.nih.gov/pubmedhealth/pmh0001827/.

Biopsy : Despite the fact that for the trained eye a nodular basal cell carcinoma is easy to identify clinically, all suspicious lesions need to be biopsied and examined under a microscope to make a definitive diagnosis.
