Human skin and its subcutaneous tissue are susceptible to develop tumors, from very small to very large ones with different characteristics and behavior during lifetime. They can be benign or malignant. The treatment of skin tumors depends on their characteristics. Some are excised for cosmetic reasons, especially if they are on the face, while others are excised because they represent a risk of turning malignant (skin cancer) or there is already a suspicion of being malignant. In case of malignant tumors surgery may be combined with other types of therapy, medications or x-ray radiation during the treatment.
