Research Interests

Associate Professor Freddy Sitas obtained a BSc in 1981, an MSC(MED) in 1987 from the University of the Witwatersrand (South Africa), an MSC in Epidemiology from the London School of Hygiene and Tropical Medicine in 1987, and a DPhil in Epidemiology from the University of Oxford in 1990. Part of his work showed for the first time that Helicobacter pylori is a cause of stomach cancer. He returned to South Africa in 1990 to the position of Head of the National Cancer Registry and in 1999 became Head of the South African MRC Cancer Epidemiology Research Group. In 2000, he was awarded a Readership in Epidemiology by the University of the Witwatersrand.

He was appointed Director of the Cancer Research Division at Cancer Council NSW in 2003.   His interests include cancer and mortality surveillance, viruses and cancer, and tobacco attributed disease.

Currently, Freddy manages our Cancer Causes Program and is a Chief Investigator on the Cervical Health Study, The Cancer Lifestyle, Evaluation And Risk Study (CLEAR), the Skin Health Study and the InterSCOPE study, amongst many others.

Following the publication of data from a study into what people think causes cancer, Freddy was interviewed, discussing how people often attribute cancer to factors outside their control, while not addressing the factors we know contribute to increased risk of cancer, which are within the control of every person.
