According to the WHO (World Health Organisation), one in every three cancers diag- nosed is a skin cancer. Between 2 and 3 million non-melanoma and 132,000 melanoma skin cancers occur each year. A project, named Globocan, supported by the International Agency for Research on Cancer, estimates the ”incidence of, mortality and prevalence from major types of cancer, at national level, for 184 countries of the world” [globocan web site]. The figures of incidence and mortality due to melanoma in the world shows that the more concerned countries are mainly developed countries but this must be linked to the reliability of the data provided by the countries (Fig. 1.1 and Fig. 1.2) [?]. There are many differences between countries depending on latitude…show more content…
Screening techniques have lead to an increase in the incidence of low density melanoma that are detected earlier. If NMSC is less dangerous, its high incidence is becoming a burden for the society as explained in [?]. Moreover a french study reported that, in France in 2011, 10.7% of people, who are treated for cancers, have a skin cancer [?]. Finally, in terms of number of hospital stay, NMSC is the secondary cause compared to other cancer. These figures show that skin cancer is a national and international health matter. If the first challenge in the treatment of skin cancer is its early diagnostic, surprisingly the tools developed to help dermatologists in this matter are sparse and still very expensive. This leads to a situation where most dermatologists only have at their disposal dermo- scopes and visual inspection to decide if the lesion is worth a histological examination. This process is still, today, the gold standard. The dermoscope is widely used but its res- olution and imaging depth are limited. Then in case of suspicion, a surgical biopsy is per- formed. In France, in 2010 , 65,200 patients have been treated for carcinoma but 539,000 biopsy have been performed because of skin cancer suspicion. Then, the percentage
