Misdiagnosis in Arizona

About Misdiagnosis

Misdiagnosis occurs when a healthcare provider incorrectly identifies a patient's condition, leading to inappropriate treatment or no treatment at all. This is one of the most common forms of medical malpractice and can result in disease progression, unnecessary procedures, or harmful medications. Cancer misdiagnosis is particularly devastating, as delayed treatment can mean the difference between a curable and terminal prognosis.
