Townsend Letter for Doctors and Patients: A new view of cancer's origins

  • "We have known for years that chronic inflammation causes cancer, yet we did not know precisely how," said Prof. Houghton. "Tissue stem cells, which are long-lived cells within organs that act to repair and replenish cells, have long been thought of as targets for carcinogens and the source of cancer. We show that bone marrow-derived stem cells attempt to participate in repair but, under conditions of inflammation, are unable to behave normally and instead progress towards cancer. This dramatically changes the way we think about cancer. If this model applies to human cancer, we will need to revise our approaches to prevention and treatment."
