Question
Chapter 5, Problem 9CRCAQ
Summary Introduction
To review:
The origin of the following types of tumors:
a) Basal cell carcinoma
b) Squamous cell carcinoma
c) Melanoma
Introduction:
A cell mass formed by the accumulation of abnormal cells is known as tumor. Various types of tumors develop in the skin. The tumors are of two types, where one is benign and the other is malignant. The major risk factor of skin cancer is the overexposure of UV (ultraviolet) rays. Skin cancers can be curable if detected in an early stage.

His surgeon recommends skin grafting procedure as his medical-surgical intervention. The surgeon explained that they are going to perform full-thickness graft that involves removing or harvesting all the epidermis and dermis from the donor site that is usually taken from the abdomen, groin, forearm, or area above the clavicle. The small pieces of skin that is removed from the donor sites will be used to cover the burned area. Though Leno know that it is a safe surgical procedure, his insight on harvesting skin from other part of his body will create a new injury and might be his skin will no longer be the same again in terms of color and texture.
