When we visit a doctor or medical professional we trust their judgement and years of training in diagnosing our health problems. However, occasionally they fail to meet these expectations and either miss signs of illness or diagnose the condition as something else.
Misdiagnosis can be summarised in two ways. The first is when an illness or condition is not diagnosed at all. The second occurs when the wrong diagnosis is made.
An example of the first type of misdiagnosis could be when a patient has visited their GP with stomach problems, but their concerns are dismissed and a diagnosis is not made, only to later discover they have a form of cancer.
