The high incidence of cancer in Australia is mainly due to C. Successful screening programs.

This conclusion is drawn from the fact that the implementation of effective screening programs in Australia has led to an increased detection rate of cancers at early stages, which results in higher reported incidences. While factors such as sun exposure and smoking rates contribute to cancer prevalence, the focus on screening significantly impacts statistics by identifying cases that might otherwise go undetected.
