Researchers in Cambridge have unveiled plans to trial a new test for throat cancer, amid hopes the device - which costs just £25 - could pave the way for more widespread national screening.
The study, which is to be conducted at several centres across the UK, will look into whether the "cytosponge" is effective in diagnosing Barrett's oesophagus - a condition which can be a precursor to throat cancer.
"If this trial is successful it will provide a cheap, safe and highly effective method of identifying people with Barrett's oesophagus," said chief investigator Dr Rebecca Fitzgerald. "This would open the doors for a national screening programme."
Cancer Research UK clinical trials director Kate Law added that throat cancer is currently one of the most difficult forms of the disease to diagnose and treat.
Last week, a report from Oxford University's Cancer Epidemiology Unit indicated that taller people could be at more risk of developing cancer, although the precise trigger remains unknown.
