Bacteria redesigned to consume tumours internally

Scientists are advancing a radical approach to cancer therapy by engineering bacteria capable of infiltrating tumours and breaking them down from within, exploiting the low-oxygen conditions at their core to trigger a controlled biological assault. Research teams across the United States, Europe and Asia are refining strains of bacteria that preferentially colonise solid tumours, particularly in regions where conventional treatments struggle to penetrate. Tumour cores are typically hypoxic, meaning they contain little oxygen. That hostile microenvironment, which limits the effectiveness of chemotherapy and radiotherapy, creates favourable conditions for certain anaerobic or facultative...
