Skin Cancer: The Facts

The Facts………. Skin cancer is the most common cancer Approximately 1 million cases per year It is estimated that nearly half of Americans will develop skin cancer by the time they turn 65

Some basic anatomy….

3 layers 1- Epidermis 2- Dermis 3- Hypodermis

Epidermis “Outer Layer” Contains Keratin- protein used to protect and water proof cells Outer layer skin cells replaced once per month Nails - dead cells that grow out of the epidermis

Dermis “Middle Layer”- gives skin elasticity Things found in the dermis: 1- Glands a. sebaceous glands- produce oil b. sweat glands- produce sweat 2- hair- you have b/w 100,000 and 200,000 hairs on your head

Hypodermis “inner layer” Attaches skin to bone and muscle Acts as insulation and cushion for organs

What is skin cancer? Skin cancer develops when abnormal cells develop and replicate in the skin tissue ( most occur in the epidermis)

Risk factors………. Light colored skin Prolonged exposure to the sun- UV radiation Age

What are the signs/symptoms…. Remember your ABC’s…………. A- Asymmetry B- Border C- Color D- Diameter

How is skin cancer diagnosed? Unusual looking skin: Biopsy X-rays Blood test Scans of liver

Three types of skin cancer…. 1- Basal cell carcinoma 2- Squamous cell carcinoma 3- Melanoma

Basal Cell Carcinoma….. Most common ( accounts for 90% of the cases) Does not spread( metastasize) Appearance: Looks like a dome-shaped bump/ texture is “pearly”

Basal Cell Continued…… Growth is slow Removal is the most common form of treatment Overall success rate of complete recovery- 90 %

Squamous Cell Carcinoma… Occur 25% as often as basal cell Can spread (metastasize) More common is men than women

Squamous Cell Continued….. Appearance: Starts out as firm, red, bump Hot spots: Occur mainly on the lower lip

Melanoma…… Most deadly form of skin cancer Develop when an existing mole changes in color or shape Begins in melanocytes

Melanocytes- cells that produce melanin, found throughout the epidermis

Type:Signsfact BasalDome shaped bump Most common SquamousRed, firm bump More common in men MelanomaResults from abnormal mole growth Most deadly

Treatment…….. Surgery Chemotherapy Anticancer drugs/perfusion Biological therapy Radiation therapy
