British zoo uses pioneering electrochemotherapy to cure cancer in giant python

Chester Zoo reported that its 4.5-metre reticulated python, Jodie Foster, has become the first snake to survive a novel cancer protocol that blends surgery with electrochemotherapy (ECT). The 23-year-old animal first showed reduced appetite, leading staff to discover a malignant tumour in her jaw, which was removed surgically. When the tumour reappeared, a second operation was performed, during which ECT was administered using bleomycin and targeted electrical pulses to destroy residual cancer cells.

Veterinarian Ian Ashpole described the complex procedure, which required two joined operating tables and temperature control measures. Post-operative checks confirmed the python is now cancer-free, eating regularly, and displaying her usual lively behaviour. University of Liverpool’s Jose Alvarez Picornell praised the collaboration and said the team will publish the method for global veterinary use.
