by Fred Hutchinson Cancer Center Credit: Pixabay/CC0 Public Domain Over the decades, scientists have revealed many strategies our cells use to keep normal cells from becoming cancerous. Now, Fred Hutchinson Cancer Center scientists have discovered a completely new—and counterintuitive—emergency brake that bladder cells use to stave off tumors even when cancer-promoting genes are turned on. In...

Researchers may have found the earliest changes that occur in seemingly healthy breast tissue long before any tumours appear, according to a new study published in the journal Nature Communications. The study, funded by Cancer Research UK, showed that before becoming cancerous, breast cells with the BRCA1 gene mutation undergo changes similar to those normally seen in late pregnancy....
by Hebrew University of Jerusalem It is a fact that has long baffled doctors: Cancer in the small intestine is quite rare, whereas colorectal cancer, a neighboring though much smaller organ, is one of the leading causes of cancer death for men and women. What is it about the colon that seems to attract cancer?...
by Manel Esteller and Alberto Bueno-Costa, Josep Carreras Leukaemia Research Institute Researchers of the Josep Carreras Leukaemia Research Institute discover that a leukaemic cell is capable of transforming into a non-cancerous cell through epigenetic changes. All the tissues of our body have the same DNA, but they perform very different functions and have very different aspects. For example, a lymphocyte and a neuron share...
