**Chennai, March 21, 2025** – Scientists are exploring a novel approach to cancer treatment using genetically engineered bacteria to target and destroy cancerous cells. This research builds upon early 19th-century immunotherapy experiments that showed bacteria could shrink tumors, although this approach was later overshadowed by chemotherapy and radiation.
Modern advancements in genetic engineering and synthetic biology are allowing researchers to program bacteria to deliver anti-cancer agents directly to tumors, potentially overcoming limitations of traditional treatments and minimizing side effects. The unique ability of certain bacteria to thrive in the low-oxygen, acidic environment of tumors is being exploited. These bacteria can either directly kill cancer cells or stimulate the body’s immune response.
While safety concerns and the complexity of the tumor microenvironment remain challenges, recent studies using engineered E. coli bacteria have shown encouraging results in laboratory animals, leading to tumor shrinkage and even complete elimination in some cases. Research focuses on solid tumors with poor blood supply and resistance to conventional therapies, such as colon, ovarian, and metastatic breast cancers. There’s also evidence suggesting that bacterial therapies can enhance the effectiveness of existing immunotherapies.
Professor Justin Stebbing of Anglia Ruskin University highlights that, although human trials are needed to confirm efficacy and safety, the potential of bacteria-based cancer therapies is significant. This approach offers a potentially powerful new weapon in the fight against cancer, offering a targeted therapy that could revolutionize cancer treatment. The future of cancer treatment may lie in harnessing the power of the very organisms once feared as disease agents.
