SKIN CANCER RISK FACTORS
August 14, 2019
1) Prolonged sun exposure: While sun exposure in the first 10 years of life determines a person’s lifetime potential for skin cancer, sun exposure in later life determines the extent to which this potential is realized. You can reduce your risk of skin cancer at any age by improving your sun protection use, whether you are 15 or 50.
2) History of sunburn: Around 10% of people with melanoma have a close relative (mother, father, brother, sister, child) with the disease. This could be because the family tends to spend more time in the sun, or because the family members have fair skin, or both. Less often, it is because of a gene change (mutation) along with sun exposure.
3) Indoor tanning habits: Ultraviolet radiation from the sun and artificial sources, such as tanning beds and sun lamps, to be a known carcinogen. Research indicates that UV light from the sun and tanning beds can both cause melanoma and increase the risk of a benign mole progressing to melanoma. Indoor tanning equipment, which includes all artificial light sources, including beds, lamps, bulbs, booths, etc., emits UVA and UVB radiation. The amount of the radiation produced during indoor tanning is similar to that of the sun, and in some cases might be stronger.
Evidence from multiple studies has shown that exposure to UV radiation from indoor tanning devices is associated with an increased risk of melanoma and non-melanoma skin cancer, including squamous cell carcinoma and basal cell carcinoma.

4) Certain types of moles: These moles look different to ordinary moles and may evolve to melanomas. If you have multiple dysplastic moles you are at greater risk of melanoma. Your doctor may recommend regular checks with a dermatologist (skin specialist).
See your doctor if you think you have moles with the following ‘dysplastic’ features:
- larger than most moles
- smudgy and irregular edges
- uneven in color
- may have some pinkness
5) Family history: Family history and hereditary factors (particularly within your immediate family), play an important part in the risk of developing skin cancer. This is demonstrated by the increased incidence of skin cancer among Caucasian people.
If one or both of your parents have had a skin cancer, you too could be at risk, especially as you are likely to have the same skin type as them. Traits such as red or blond hair, light colored eyes, fair skin, sun sensitive skin, and a tendency to freckle are genetic risk factors for developing melanoma and non-melanocytic skin cancers when combined with UV exposure.
6) Skin that freckles and burn easily: Some people are more likely to get freckles than others, depending on their genes and skin type. If a person is genetically more likely to develop freckles, exposure to sunlight can make them appear.
Freckles are common in children and may disappear or become less noticeable as they grow up.
7) Red and blonde hair: There are groups of people who are at a higher risk of developing melanoma. Those who have fair skin, red or blonde hair, light-colored eyes, or skin that freckles easily are all more vulnerable to the sun. Since people with these traits naturally have less melanin pigment, they also have less protection from UV radiation. Melanoma is 20 times more common in white people than it is in people of color.
8) Blue or green eyes: New research suggests that genes tied to blue eyes and red hair could put people at higher risk for moles or freckling in childhood, which are often precursors to the deadly skin cancer melanoma later in life.
