Signs of cancer may also not be clear or obvious and GPs see, on average, only around eight new cases a year. A full time GP will have between 6,000-8,000 appointments every year. And they will only have around 10 minutes per appointment to pick out warning signs that could be cancer, but equally may be a symptom of a less serious condition.
Sarcoma UK’s On The Ball campaign is still going to help with diagnosis.
