Cancer refers to a group of diseases that involve abnormal cell growth in one or more parts of a body which may also spread to other parts of the body. Cancers that arise from the skin are called skin cancers. They can be categorized mainly into three types, basal-cell cancer (BCC), squamous-cell cancer (SCC), and melanoma. Basal skin cancer grows gradually and damages the surrounding tissue. It becomes visible as a raised area of skin that appears shiny with small blood vessels running over it. It may also appear as a raised area with an ulcer. The most common form of treatment for skin cancers is surgical excision or reconstructive surgery. Human papillomaviridae (HPVs) are small non-enveloped viruses belonging to the Papillomaviridae family. There are five main classes or genera of HPVs namely α, β, γ, ν, and µ. Out of these five, α-HPV and β-HPV are known to play a role in human diseases. α-HPVs play an etiological role in mucosal and skin infections as well as cervical carcinoma and benign viral warts. β-HPVs have been associated with skin infections and SCC. This book presents various researches on the role of viruses in the development of skin cancers. Those in search of information to further their knowledge will be greatly assisted by this book.

The type of cancer that involves an abnormal growth of skin cells is called skin cancer. There are three prominent forms of this type of cancer named as basal cell carcinoma, squamous cell carcinoma, and melanoma. The main reason for development of skin cancer is exposure of skin to sun, and usually includes lips, ears, neck, face, and scalp. Basal cell carcinoma may appear like a pearly or waxy bump or as a flat, flesh colored scar-like lesion. Squamous cell carcinoma often affects people with darker skin tone and appears as a firm red nodule or as a flat lesion with a scaly crusted surface. The signs of melanoma include a large brownish spot with darker speckles, a painful lesion that itches or burns, or as a mole that changes in color and size. A weakened immune system, exposure to radiation, a personal history of skin cancer, fair skin, and excessive sun exposure are some factors that increase the risk of skin cancer. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the prevention and treatment of skin cancer. It aims to shed light on some of the unexplored aspects of this disease. The book will serve as a reference to a broad spectrum of readers.

Procedural dermatology refers to the specialty within dermatology which focuses on the diagnosis, study and treatment through surgery of the diseases which affect the skin. It also deals with cutaneous appendages, hair, nails, mucous membranes and subcutaneous tissue. The procedures within this field are generally performed on outpatient basis and are minimally invasive. Some of the procedures which are conducted within this procedural dermatology are sclerotherapy, cutaneous reconstruction of surgical defects, hair transplantation, Mohs micrographic surgical excision and small-volume liposuction. Sclerotherapy refers to the form of treatment wherein medicine is injected into the blood vessels in order to cause them to shrink. Procedural dermatology is an upcoming field of science that has undergone rapid development over the past few decades. The aim of this book is to present researches that have transformed this discipline and aided its advancement. It is a vital tool for all researching and studying this field.
