Doctors in America have been left baffled after a cancer patient developed an "uncontrollable" Irish accent - despite never visiting the country.
The 50-year-old man from North Carolina was diagnosed with prostate cancer when he appeared to develop foreign accent syndrome (FAS), according to the British Medical Journal.
The rare syndrome is seen in patients who have suffered strokes or head injuries but this is the first time it's been seen in a prostate cancer patient, according to research by Duke University in North Carolina and the Carolina Urologic Research Center in South Carolina.
