Cancer treatments began with aggressive chemical cocktails and evolved with the creation of drugs from cells. Now, living beings can be incorporated into the war against these diseases. A few days ago, a team of researchers from the universities of San Diego (USA) and Adelaide (Australia) presented in the magazine Science a work in which modified bacteria were used to detect tumor DNA in the intestines of mice. This capacity could be incorporated into those explored by other projects, who have managed to use bacteria designed to carry therapeutic loads to the interior of solid tumors, overcoming the barriers with which they protect themselves from the immune system and the difficulties in reaching them with medications.
