“Skin cancer is highly prevalent, it takes time to develop and is curable, provided there is an early diagnosis , ” says Moreno Giménez, president of the Spanish Academy of Dermatology and Venereology (AEDV). On the occasion of World Cancer Day (4 February) the association has used to remember the importance of regular checkups.
Within the skin cancer there are two ways different:
• Tumors derived from epithelia. It is also known as non – melanoma skin cancer. In turn may be two forms: basal cell carcinoma and espincoelular carcinoma.
• tumors derived from melanocytes. Melanoma is undoubtedly the most malignant tumor is known. It comes to have a 5 – year survival close to 98 percent if it is removed in its infancy.
Moreno warns that ” the non – melanoma skin cancer is the most common tumor, with what we could say that 1 in 5 people will develop skin cancer during their life.” Of basal cell carcinoma are diagnosed 71 new cases per 100,000 inhabitants / year, while the squamous cell carcinoma 20 cases per 100,000 inhabitants / year.
The specialist reports that melanoma has increased its frequency 1000 in the last 20 years , but has not gotten worse prognosis, since it has made progress in early diagnosis. ” It is the least common of the cutaneous malignant tumors, accounting for 4 percent of all of them, although it is responsible for 80 percent of deaths from this cancer.”
However, Moreno currently affects about 160,000 cases a year are diagnosed worldwide and represents about 1.5 percent of all cancers in both sexes, being the fifth most common tumor in men and the sixth in women. In Spain, where the melanoma is more common in women as in the rest of Europe are diagnosed each year approximately 3,200 new.
