We have all been assured by doctors and the manufactures of sunscreen that it is the most basic and safe way of guarding against skin cancer.
But in recent years studies have suggested that sunscreen may not prevent some forms of skin cancer.
Research published in the journal Nature found that sunscreen can protect against sunburn, but cannot protect against skin damage from ultraviolet rays (UV).
It can be hard to avoid the effects of UV rays as they can reach you on a cloudy and hazy day, as well as bright and sunny days. UV rays also reflect off of surfaces like water, cement, sand, and snow. Indoor tanning (using a tanning bed, booth, or sunlamp to get tan) exposes users to UV radiation as well.
The Centers for Disease Control and Prevention (CDC) says that the hours between 10 a.m. and 4 p.m. Daylight Saving Time (9 a.m. to 3 p.m. standard time) are the most hazardous for UV exposure outdoors in the continental United States. UV rays from sunlight are the greatest during the late spring and early summer in North America.
The CDC also says that dangerous UV radiation emitted from the sun and tanning beds are the primary reason for the skyrocketing incidence of melanoma over the last three decades.
Therefore, it has always been taunted by the medical community that UV rays make us more vulnerable to skin cancer.
We need to ask though, what is really causing skin cancer – the sun or the administration of a sunscreen lotion?
