Commonly known as skin cancer
-Over exposure to UV light
-Precancerous skin lesions.
-Family history of skin cancer
-Weakened immune system
-Exposure to radiation or harmful chemicals
The three different types of skin cancer
- Squamous cells lie just below the outer surface and function as the skin's inner lining.
- Basal cells, which produce new skin cells, sit beneath the squamous cells.
- Melanocytes, cells that produce melanin, are located in the lower part of your epidermis. Melanocytes produce more melanin when you're in the sun to help protect the deeper layers of your skin.
Basal cell carcinoma may appear as:
- A pearly or waxy bump
- A flat, flesh-colored or brown scar-like lesion
- A firm, red nodule
- A flat lesion with a scaly, crusted surface
Melanoma signs include:
- A large brownish spot with darker speckles
- A mole that changes in color, size or feel or that bleeds
- A small lesion with an irregular border and portions that appear red, white, blue or blue-black
- Freezing (cryosurgery). Destroying early skin cancers with liquid nitrogen
- Excisional surgery. Cutting out diseased tissue
- Radiation therapy. Using high-powered energy beams to kill cancer cells
- Chemotherapy. Using drugs to kill cancer cells
- Biological therapy. Biological treatments stimulate your immune system in order to kill cancer cells.
-One person dies of melanoma every hour
-About 86 percent of melanomas can be attributed to exposure to ultraviolet (UV) radiation from the sun
-The overall 5-year melanoma survival rate for African Americans is only 77 percent, versus 91 percent for Caucasians
-The estimated cost of treating melanoma in 2010 was $2.36 billion
