Basal cell carcinoma is the most commonly diagnosed type of skin cancer. It is estimated that 75% of non-melanoma skin cancer cases are basal cell carcinomas. So, what exactly causes it?

UV Rays

Ultraviolet rays from the sun and from tanning beds are the primary risk factors for developing BCC. It is important to stay out of the sun during its peak times (10 a.m.-2 p.m.), as this is when the sun's rays are at their hottest. When outdoors, wear sunscreen, even when it is shady!

Skin Tone

Fair skinned people have a higher risk factor for developing basal cell carcinoma. Keep in mind that when exposed to UV rays, all skin tones are at risk!

Basal Cell Nevus Syndrome

This syndrome is a genetic disorder that causes tumors to develop at early ages. People with syndromes like basal cell nevus syndrome, are more sensitive to UV rays.

Other Factors

Other risk factors for development include radiation therapy treatment and immune suppression therapy.

The bottom line is that the best defense for the average, healthy person against BCC is the use of sun screen! Br sun smart- an ounce of prevention is really worth a pound of cure when it comes to skin cancer!
