Cancer Epidemiology

The epidemiology of cancer is the study of the features affecting cancer, as a way to assume possible trends and causes. The study of cancer epidemiology uses epidemiological methods to discover the source of cancer and to recognize and progress improved treatments.

This extent of study must resist with problems of lead time bias and length time bias. Lead time bias is the notion that early diagnosis may artificially inflate the survival statistics of a cancer, without really improving the usual history of the disease. Length bias is the concept that slower growing, more indolent tumors are more likely to be analyzed by screening tests, but improvements in diagnosing more cases of indolent cancer may not interpret into better patient outcomes after the implementation of screening programs.
