When you?re told that you have skin cancer, it?s natural to wonder what may have caused the disease. The main risk factors for skin cancer is exposure to sunlight (UV radiation), but there are also other risk factors. A risk factor is something that may increase the chance of getting a disease.

People with certain risk factors are more likely than others to develop skin cancer. Some risk factors vary for the different types of skin cancer.

Risks for Any Type of Skin Cancer
Studies have shown that the following are risk factors for the three most common types of skin cancer:

Sunlight: Sunlight is a source of UV radiation. It?s the most important risk factor for any type of skin cancer. The sun?s rays cause skin damage that can lead to cancer.

Severe, blistering sunburns: People who have had at least one severe, blistering sunburn are at increased risk of skin cancer. Although people who burn easily are more likely to have had sunburns as a child, sunburns during adulthood also increase the risk of skin cancer.

Lifetime sun exposure: The total amount of sun exposure over a lifetime is a risk factor for skin cancer.

Tanning: Although a tan slightly lowers the risk of sunburn, even people who tan well without sun burning have a higher risk of skin cancer because of more lifetime sun exposure.

Reflected sunlight: Reflected sunlight by sand, water, snow, ice, and pavement. The sun?s rays can get through clouds, windshields, windows, and light clothing.

Proximity to equator: In the United States, skin cancer is more common where the sun is strong. For example, more people in Texas than Minnesota get skin cancer. Also, the sun is stronger at higher elevations, such as in the mountains. Doctors encourage people to limit their exposure to sunlight.

Sunlamps and tanning booths: Artificial sources of UV radiation, such as sunlamps and tanning booths, can cause skin damage and skin cancer. Health care providers strongly encourage people, especially young people, to avoid using sunlamps and tanning booths. The risk of skin cancer is greatly increased by using sunlamps and tanning booths before age 30.

Personal history: People who have had melanoma have an increased risk of developing other melanomas. Also, people who have had basal cell or squamous cell skin cancer have an increased risk of developing another skin cancer of any type.

Family history: Melanoma sometimes runs in families. Having two or more close relatives (mother, father, sister, brother, or child) who have had this disease is a risk factor for developing melanoma. Other types of skin cancer also sometimes run in families. Rarely, members of a family will have an inherited disorder, such as xeroderma pigmentosum or, nevoid basal cell carcinoma syndrome, that makes the skin more sensitive to the sun and increases the risk of skin cancer.

Having fair (pale) skin: Skin that burns easily: in the sun easily, blue or gray eyes, red or blond hair, or many freckles increases the risk of skin cancer.

Certain medical conditions or medicines: Medical conditions or medicines (such as some antibiotics, hormones, or antidepressants) that make your skin more sensitive to the sun increase the risk of skin cancer. Also, medical conditions or medicines that suppress the immune system increase the risk of skin cancer.

Other Risk Factors for Melanoma

The following risk factors increase the risk of melanoma:
Dysplastic nevus: A dysplastic nevus is a type of mole that looks different from a common mole. A dysplastic nevus may be bigger than a common mole, and its color, surface, and border may be different. It?s usually wider than a pea and may be longer than a peanut. A dysplastic nevus can have a mixture of several colors, from pink to dark brown. Usually, it?s flat with a smooth, slightly scaly or pebbly surface, and it has an irregular edge that may fade into the surrounding skin.

A dysplastic nevus is more likely than a common mole to turn into cancer. However, most do not change into melanoma. A doctor will remove a dysplastic nevus if it looks like it might have changed into melanoma.

More than 50 common moles: Usually, a common mole is smaller than a pea, has an even color (pink, tan, or brown), and is round or oval with a smooth surface. Having many common moles increases the risk of developing melanoma.

Other Risk Factors for Both Basal Cell and Squamous Cell Skin Cancers
The following risk factors increase the risk of basal cell and squamous cell skin cancers:

1. Old scars, burns, ulcers, or areas of inflammation on the skin

2. Exposure to arsenic at work

3. Radiation therapy

Other Risk Factors for Squamous Cell Cancer

The risk of squamous cell skin cancer is increased by:

Actinic keratosis: Actinic keratosis is a type of flat, scaly growth on the skin. It is most often found on areas exposed to the sun, especially the face and the backs of the hands. The growth may appear as a rough red or brown patch on the skin. It may also appear as cracking or peeling of the lower lip that does not heal. Without treatment, this scaly growth may turn into squamous cell skin cancer.

HPV (human papillomavirus): Certain types of HPV can infect the skin and may increase the risk of squamous cell skin cancer. These HPVs are different from the HPV types that cause cervical cancer and other cancers in the female and male genital areas.

About SIMSYS-MoleMate
The FDA approved SIMSYS-MoleMate Skin Imaging System, a non-invasive skin cancer screening procedure, is a significant advance in the early detection of potentially life threatening moles and lesions.
Physicians have found the SIMSYS-MoleMate Siascope hand-held device easy to learn and use, and that it rapidly provides accurate images of the pigment, blood, and collagen below the mole or lesion.

Now, for the first time, physicians can more accurately evaluate suspicious moles and lesions in a non-invasive, pain-free way. Experts also believe it may reduce the need for time consuming and expensive biopsies.
