Mornings With John Mackenzie

John MacKenzie chats with Associate Professor Michelle Wykes, Group Leader of Molecular Immunology at QIMR Berghofer Medical Research Institute, about breakthrough cancer research in regard to both breast and bowel cancer. The discovery of a so-called "master switch" is being understood in efforts to potentially turn on vital dendritic cells, which act like the generals of the immune system, to fight particular tumours. "We're seeing palpable tumours that completely disappear and melt away," Michelle Wykes said.
