Basal-cell carcinoma
In the United States approximately 3 out of 10 caucasians develop a basal-cell carcinoma during their lifetime. This tumor accounts for approximately 70% of non-melanoma skin cancers. In 80 percent of all cases, basal-cell carcinoma affects the skin of head and neck. Furthermore, there appears to be an increase in the incidence of basal-cell cancer of the trunk in recent years.
Skin cancer in Australia
Melanoma, basal cell carcinomas and squamous cell carcinomas are predominantly caused by exposure to ultra violet radiation (UVR), and both UVA and UVB radiation has internationally been categorised as carcinogenic. Artificial UVR primarily used in tanning salons and sunbeds, has generated concern among health officials and it was observed to considerably heighten the risk of developing cutaneous malignant melanoma. A study in 2010 found strong evidence supporting association between indoor tanning salon use and increased risk of developing melanoma. The study demonstrated strong correlations between increased risk of melanomas and carcinogenic ultraviolet radiation related outcomes. These increased risks were specifically associated with younger participants, with tanning and solarium use relatively popular among teens and young adults. An increase of 59% in risk of developing melanoma was associated with people who used sun beds before they were 35.
