What does it mean if a medical condition is said to 'recur'?

When a medical condition is described as 'recur,' it signifies that the condition has manifested again after a period of improvement or absence. This recurring nature implies that the issue resolved temporarily, allowing for a period during which the individual might have been symptom-free, only for the same condition to return later. Understanding this term is crucial for both patients and healthcare providers, as it often influences treatment plans and long-term management strategies. In contrast, the other options describe different situations: stability suggests the condition has not changed; resolution means it has healed completely, with no expectation of return; while going undetected refers to conditions that are present but not identified.
