Delayed Diagnosis in New York

About Delayed Diagnosis
Delayed diagnosis occurs when a healthcare provider fails to identify a medical condition in a timely manner, allowing the disease to progress to a more advanced and less treatable stage. Unlike misdiagnosis, the correct diagnosis is eventually made, but the delay causes measurable harm to the patient. These cases are especially common in cancers, heart disease, and infections where early intervention is critical to survival.
