Answer

Patients who live close to the equator tend to present with cSCC at a younger age than do patients who live more distant from it.

The highest incidence of cSCC occurs in Australia, where nonmelanoma skin cancer incidences as high as 1.17 per 100, a rate 5 times greater than all other cancers combined, have been reported. [26] The high incidence is likely due to the large numbers of light-skinned people in this region who have had extensive sun exposure. [27]
