detected

A more pertinent subsea sound was detected by the US Navy’s sonar system at the time the sub went missing - an acoustic signal consistent with an implosion.

When it leaves the body, it can be detected to show its size and location on a scanner.

A lung-cancer screening programme that sees mobile clinics visit local communities in England has detected the disease earlier in more than 5,000 people.

Since the programme's launch, in 2019, 5,037 lung cancers have been detected, with 76% of those at the earliest stages of the disease.

People are nearly 20 times more likely to survive for five years if their cancer is detected early, experts say.
