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 »
