Page 2: 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

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….

Page 4: 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

3 layers

1- Epidermis

2- Dermis

3- Hypodermis

Page 5: 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

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

Page 6: 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

Dermis

“Middle Layer”- gives skin elasticityThings found in the dermis:

1- Glandsa. sebaceous glands-

produce oilb. sweat glands- produce

sweat2- hair- you have b/w 100,000 and

200,000 hairs on your head

Page 7: 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

Hypodermis

“inner layer”

Attaches skin to bone and muscle

Acts as insulation and cushion for organs

Page 8: 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

What is skin cancer?

Skin cancer develops when abnormal cells develop and replicate in the skin tissue

( most occur in the epidermis)

Page 9: 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

Risk factors……….

• Light colored skin

• Prolonged exposure to the sun- UV radiation

• Age

Page 10: 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

What are the signs/symptoms….

Remember your ABC’s………….A- Asymmetry

B- Border

C- Color

D- Diameter

Page 11: 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

How is skin cancer diagnosed?

Unusual looking skin:• Biopsy

• X-rays

• Blood test

• Scans of liver

Page 12: 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

Three types of skin cancer….

1- Basal cell carcinoma

2- Squamous cell carcinoma

3- Melanoma

Page 13: 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

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”

Page 14: 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

Basal Cell Continued……

• Growth is slow

• Removal is the most common form of treatment

• Overall success rate of complete recovery- 90 %

Page 16: 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

Squamous Cell Carcinoma…

• Occur 25% as often as basal cell

• Can spread (metastasize)

• More common is men than women

Page 17: 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

Squamous Cell Continued…..

Appearance: Starts out as firm, red, bump

Hot spots: Occur mainly on the lower lip

Page 18: 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
Page 19: 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

Melanoma……

• Most deadly form of skin cancer

• Develop when an existing mole changes in color or shape

• Begins in melanocytes

Page 20: 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

•Melanocytes- cells that

produce melanin, found

throughout the epidermis

Type: Signs fact

Basal Dome shaped bump

Most common

Squamous Red, firm bump

More common in men

Melanoma Results from abnormal mole growth

Most deadly

Page 23: 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

Treatment……..

• Surgery

• Chemotherapy

• Anticancer drugs/perfusion

• Biological therapy

• Radiation therapy
