There have been many who know if cancer is a
very dangerous disease, skin cancer is no exception, the many types of skin
cancer, but not all dangerous skin cancer, the following are the types of skin
cancer and other:
• Kaposi's Sarcoma.
Kaposi's Sarcoma occurs due to viral infections that cause mutations in
endothelial cells, shaped like a red or purple
spot on the network under the skin. Kaposi's Sarcoma can occur in people
with impaired immune systems such as people with AIDS or organ transplant
recipients, infected by human herpesvirus 8 (HHV-8).
• Merkel cell carcinoma.
Merkel cells are cells that are located close to the nerve endings in the skin and related to the function of the skin as
the senses are sensing. Merkel cells in malignancy are extremely rare and led to
the formation of hard bumps under the skin or in the hair follicles.
• Carcinoma of oil glands (sebaceous glands).
Cancer of the sebaceous glands is rare
cancer, but are aggressive. Cancer generally appears in the sebaceous glands
oil glands in the skin, then formed a hard lump does not feel sick. Sebaceous
cancer can occur anywhere, but usually occurs in the eyelids and often
misdiagnosed as other eye disorders.
Not
all disorders or bumps in the skin caused by cancer, but skin cancer also often
appear in the form of mild abnormalities of the skin, therefore the doctor's
diagnosis is very important in determining the causes and types of
abnormalities in it.
Causes
Of Skin Cancer
Generally, skin cancer caused by exposure to
ultraviolet light causing DNA damage in skin tissue. The main source of
ultraviolet light is sunlight consisting of three types, namely:
•
Ultraviolet
A (UVA)
•
The Ultraviolet B (UVB)
•
Ultraviolet C (UVC)
Of
the three types of ultraviolet rays, which are most harmful to the skin is a
UVC ray. UVC rays, however, can be
absorbed by the atmosphere before it reaches the ground. UVA and UVB can damage
skin cells, especially the pale-colored,
and potentially cause skin cancer.
Artificial
UV light sources such as lamps and UV tanning bed can also cause skin cancer.
Some
factors that can increase a person's risk of developing cancer of the skin are:
•
have a white skin. Everyone can develop skin cancer, regardless of the color of
their skin. But Whites have protection against UV rays are weaker compared with
darker skin. Darker skin has melanin more so that has protection against UV
rays are stronger. In addition to easy spots formed on the skin indicate that
more vulnerable skin exposed to skin
cancer.
•
Frequent exposure to sunlight. People are often exposed to the Sun's rays are
more at risk of experiencing skin cancer compared with those who rarely exposed
to sunlight. Some conditions that can increase the exposure to sunlight, among
others
• live
in an area that has a bright.
• live in higher areas.
•
moles. People who have a lot of moles or moles that have abnormal (larger than
normal) are exposed to a higher risk of
skin cancer compared to people who have a little Mole.
•
age. People with advanced age are more easily affected by skin cancer compared
with children or teenagers.
•
Skin ever sunburn (sunburn). Skin
blisters due to the sunlight make the
skin more at risk of developing cancer of the skin, especially if the skin blister occur at the time of children or
teenagers.
•
Actinic keratosis. In people with skin tone brighter, exposure to sunlight is
easy to cause the formation of spots in
the form of a scaly skin thickening on the face, hands, and head. This
condition is pre-cancer, and very
potentially turning into skin cancer.
•
a history of skin cancer. If a person never had skin cancer and was cured, it
is possible that the same condition would reappear.
•
a history of skin cancer in a family member. A person exposed to a high risk of
skin cancer if you have a sibling or parent had ever suffered from skin cancer.
•
The weakening of the immune system.
People with a weak immune system have a high risk of developing cancer of the
skin. Including HIV/AIDS, people who are taking the immunosuppressant
medication, and organ transplant recipients.
•
radiation therapy. Eczema or acne sufferers are given
radiation therapy had a higher risk of developing cancer of the skin,
especially basal cell cancer.
•
Exposure to certain chemicals. Various carcinogenic chemicals, such as arsenic,
can also increase the risk of developing the
skin cancer.
