People frequently ask “Does ultraviolet (UV) radiation cause cancer?” Many still doubt it and search for the truth. The fact is, it does. Excessive exposure to UV radiation can cause genetic mutations to DNA that can lead to skin cancer. In fact, it is the leading cause of non-melanoma skin cancers.
Skin cancer is a major concern for people who work under the sun. The risk is avoidable through greater awareness of the problem and by taking precautionary measures. Skin cancer develops in the cells in the outer layer of the skin. UV radiation is made up of UVA and UVB rays which may cause permanent damage to the cells. When UVA penetrates deeply into the skin, it may lead to photo-ageing and immune suppression. Meanwhile, UVB causes sunburn, a significant risk factor for skin cancer.
Your body has ways of repairing most of the damage, but if it does not respond right, cells can begin to divide and grow in an uncontrolled way. This growth can eventually form a tumour.
There are a number of mistaken beliefs about sun exposure, skin cancer and vitamin D. Look at the facts behind the fiction:
Fact: Tinted cars can block 60 percent to 70 percent of UV radiation to penetrate
Industry veteran tintworks.com.au says window tint solutions for Adelaide houses and cars are capable of absorbing a large amount of heat that may cause skin cancer.
Myth: Sunscreen is a great sun protection
No lotion is 100 percent protective.
Fact: UV radiation can still be high on a cloudy day
Clouds do not block the sun’s UV radiation, though there is no visible light.
Myth: Sun exposure helps to obtain vitamin D
Vitamin D can be obtained safely from food or supplements without being exposed from the harmful UV radiation.
Fact: Skin cancer is more common in fair-skinned people
Fair-skinned people are sensitive to sun exposure; they easily burn. They are prone to skin damage and high risk for melanoma, the deadliest type of skin cancer.
Myth: Tan people are more resistant to UVR exposure
A tan is only equivalent to a sunscreen with an SPF two or four. It means it is not sufficient to provide essential protection from skin cancer.
If you see the sunlight, seek the shade. Stay protected. Remember: health is wealth.
