Skin Cancer Prevention
The main risk factor for cancer is overexposure to ultraviolet radiation.
Avoid intense or prolonged sun exposure, trying not to be exposed at times when the solar radiation is larger is the best preventive measure that can be used.
Other forms include using materials that protect those sensitive areas such as the use of hats, sunglasses that absorb UV rays by 99% to 100%, or using appropriate fabrics to cover the skin.
Most inexpensive fabrics that are made of light colored summer clothes do not have ultraviolet filters let through much of this kind of radiation. It should be sunscreen in the trunk if it is to remain long in the sun, even wearing t-shirt.
The use of sunscreens reduces the risk of exposure. Must be used correctly, there are different degrees depending on the type of skin. They should be used with a time of sun exposure before and get better after bathing in the sea or pool.
As seen, the booths and tanning lamps are dangerous and should therefore be used with caution, avoiding excessive tanning.
When you notice a mole that has changed in appearance, or bleeding, call your doctor. This can be removed and biopsied to see if it is malignant or not.
This type of cancer can be prevented more than many others. Following the instructions above can be reduced or canceled much of the risk factors, so that the chances of developing skin cancer also decreased.
Skin Cancer Risk Factors: Genetic and Other Factors
Genetic factors
The nevoid basal cell epithelioma syndrome is an inherited disorder in which patients develop numerous basal cell carcinoma from the second decade of life and that ultimately affect any area of the skin.
Xeroderma pigmentosum is an inherited disorder that is caused by an alteration in DNA repair, is also associated with the occurrence of multiple cutaneous carcinomas.
In cutaneous malignant melanoma has been described a familial predisposition. The estimated risk is 70% present in patients with neurocutaneous melanosis and different types of xeroderma pigmentosum, from 1% in children of patients with non-familial melanoma alone and 6% in families with dysplastic nevus syndrome and history of two or more malignant melanomas.
Those who have been treated with medicines that suppress their immune systems, are more likely to develop melanoma. Read the rest of this entry »
Skin Cancer Risk Factors: Physical Characteristics Factors
Physical Characteristics
The white people of Scottish, English or Irish with blond or red hair, blue eyes and abundant freckles are especially susceptible.
Melanoma is very rare in the population being predominantly black or Oriental, when it occurs, little pigmented areas such as palms and plants and their prognosis is worse. The sensitivity of skin to sun tanning and the difficulty increases the risk of melanoma.
The skin reaction to sunlight is associated with factors such as skin pigmentation, the number of freckles in childhood or adulthood and the number of nevi (moles-like formations, which are benign melanocytic tumors), accounting for all factors risk for cutaneous malignant melanoma.

Skin Cancer Risk Factors: Environmental Factors
The reason that causes this type of cancer is not entirely known. Yes, we have studied some factors that influence their occurrence.
Environmental factors
Excessive exposure to the sun influences the production of these cancers. People who work outdoors, such as farmers and sailors, have a higher incidence. Often occur on exposed skin, often in head and neck.
Although sunlight helps to synthesize vitamins A and D, overexposure, produce or burns, increases the risk of developing skin cancer, including malignant melanoma.
There is a correlation between risk of melanoma and latitude. It also influences the time period during which a person has lived in Ecuador-latitude countries, which means excessive sun exposure maintained for a period of life. Read the rest of this entry »
Types of Skin Cancer: Melanoma
Melanoma skin cancer
This disease develops in the melanocytes, skin cells that produce melanin that gives color. Melanocytes are found in the epidermis, layer of outer skin.
Melanoma is the type of skin cancer less common and more severe. You can easily spread to other parts of the body through blood or lymphatic system. If diagnosed early, the prognosis is better.
It can occur from existing moles, or a new formation, small, pigmented, appearing in an area of normal skin.
Will have to consult with your doctor if you notice a change in the size, shape or color of a mole. Or a mole that is swollen or painful to the touch or oozing or bleeding. Read the rest of this entry »
Other Types of Skin Cancer: Kaposi’s Sarcoma
Other less common types:
* Kaposi’s sarcoma: originates in the dermis but can also occur in internal organs.
Kaposi sarcoma in two forms:
That which usually develops in those patients with acquired immunodeficiency syndrome (AIDS) and children and young people of equatorial Africa. This form grows very fast and tends to affect internal organs.
Before the onset of the disease, tended to present only the elderly of European origin Mediterranean. In these people grows very slowly on the skin and rarely spreads.
In the first the characteristic appearance is a sin pink, red or purple round or oval, in any part of the body but more often in the face. Read the rest of this entry »
