Skin type and UV exposure are considered the most important risk factors for skin cancer.

Compare the risk estimates for the skin characteristics (OR around 2) with the risk of other risk factors for cancer, such as smoking for lung cancer (OR around 20).

What may explain the relatively low risk estimates for the skin?

This may be due to the geographical location and climate in this part of Central Europe. Sun light exposure is much lower than in Australia and many other geographical regions.
