What is melanoma?
Melanoma is a type of skin cancer and is considered to be most
dangerous form of the disease. Although less commonly diagnosed than
other types of skin cancer, melanoma account for over 75% of skin cancer
deaths.
Melanoma develops in cells called melanocytes.
Melanocytes are cells that are responsible for creating skin
pigmentation, or melanin. Melanin is what gives our skin its natural
hue.
As skin is exposed to UV rays of the sun, more melanin is
produced, in hopes to prevent burning of the skin. The end result is
damage to the DNA in skin cells. UV rays can also be found in tanning
booths and lamps, so indoor tanning is not any safer.
People with
many moles are at a higher risk for developing melanoma. Although most
moles are benign, there are certain types that carry a higher risk, such
as dysplastic nevi, also referred as atypical moles. They often have a
melanoma-like appearance.
Caucasians are 20 times more likely to
develop skin cancer than African Americans. This is due to the
protection of the skin pigmentation. Those with red hair, light
complexions or freckles, are also at a higher risk for developing
melanoma. However, regardless of skin color, there is a risk factor when
the skin is being exposed to UV rays.
There are other risk
factors for developing melanoma such as family history of the disease,
certain medications, and genetics. Gender also plays a role as men
develop melanoma at a higher rate than females.
Melanoma can be
life threatening if left untreated or diagnosed in late stages. There
are medications and therapies for the disease. But, early detection is
key. When detected early, there is an excellent survival rate.
