Cancer researcher Manel Esteller has been investigating the development of breast cancer. His team has discovered that environmental and lifestyle factors play a role in determining when a cancer-causing genetic mutation is "switched on".
Scientists are learning more about the effect of smoking on genes, including the DNA in organs that don't come into contact with tobacco fumes. Smoking leaves mutations that can last decades after quitting.
The future isn't far off, according to US researchers: doctors will soon be able to detect cancer and locate tumor cells just by examining one blood sample. But is this new screening method as good as it sounds?
