Medical Malpractice Claims for Mental Health
If properly and timely diagnosed, most forms of cancer have a high recovery rate. The prognosis worsens the longer the cancer progresses without medical intervention. Early detection is critical to survival rate and allows less-invasive treatment options.
Advances in medicine allow doctors to detect cancers at very early stages. In spite of these technologies, some doctors dismiss reported complaints or do not order appropriate tests necessary for early detection. Because any delay can be costly, a medical professional who fails to diagnose cancer leaves the patient at risk of a bad outcome.
The majority of medical malpractice claims allege that a doctor fell below the standard of care by failing to diagnose a serious medical condition. The most common diseases that are not diagnosed are breast cancer, colon cancer, melanoma and lung cancer. Failure to diagnose these conditions in a timely manner often results in death.

Do I have a Viable Medical Malpractice Claim if My Doctor Failed to Diagnose Cancer?
The first step in a medical malpractice claim for failure to diagnose is proving that the doctor fell below the standard of care with respect to the treatment. This can occur when a doctor fails to order appropriate tests or misinterprets the results.
A failure to diagnose on its own, however, does not give rise to a medical malpractice claim. The patient must prove the delay in providing a proper diagnosis negatively impacted the outcome. When the condition results in the death of the patient, this is demonstrated by evidence that the patient likely would have survived but for the misdiagnosis. In other cases, harm can be proven by a prognosis that is worse than what would have occurred if the cancer was diagnosed timely.
