A new method of diagnosing bladder cancer has been developed by researchers at the University of Texas MD Anderson Cancer Centre.
The team identified a method of locating the cancer at its earliest stages through determining the presence or absence of microRNA.
Existing laboratory tests are sufficient to determine the presence of this non-coding part of DNA.
Liana Adam, assistant professor at the university, commented: "Measuring expressions of microRNA in bodily fluid represents a very promising tool with widespread implications for screening."
However, she added: "This needs further validation, but we could reasonably use this method for widespread screening of bladder cancer."
Certain microRNAs had previously been shown to be dysregulated in the blood of people with bladder cancer.
Statistics from Cancer Research suggest that bladder cancer is the seventh most common cancer in the UK.
The charity claims that around 10,300 people are diagnosed with the condition every year.
