THE NHS's top cancer doctor has revealed 18 cancer symptoms everyone should know, after a survey found that a worrying number of Brits wouldn't be able to spot red flag signs of the killer disease.
A new NHS survey of 2,000 Brits tested people's knowledge of common cancer symptoms.

Most respondents had no idea that lasting three weeks or more was something to be worried about, as just 21 per cent recognised it as a possible sign of cancer.
More than half (55 per cent) didn't know that – even if it just happens once – could be a sign of disease.
Almost half (49 per cent) didn't recognise unexplained weight loss as a symptom, and more than four in 10 people (42 per cent) didn't flag an as a potential sign of cancer.
TheNHSadvises people to regularly check for any new lumps or unexpected changes in the body to help identify any possible symptoms of cancer.

In fact, respondents were more likely to check their bank balance, forecast or sports results than give their body a once over for worrying changes.
While most bodily changes are unlikely to be cancer, it’s important to get any new or worrying symptoms checked out by a GP as soon as possible so they can help rule cancer out.
