Instead of suing someone for medical misdiagnosis, can you sue for misdiagnosis when it happened in a hospital? If this the case, then it depends on whether the doctor, who did the diagnosis, is an employee of that certain medical institution or not. When a hospital employee commits an error while doing his or her duties, the hospital takes full responsibility for the damages. The principle of an employer’s liability has indicated that any act or omission made by the employee during his or her employment, which has resulted in damages, losses, or suffering, can be liable to the employer, in this case, the hospital. That being said, when a doctor is an employed individual of a hospital, then all his or her actions are attributed to the medical institution, hence, suing the hospital for a misdiagnosis is possible.
Most states have case law requiring courts to simultaneously treat those who represent themselves, known as pro se (pronounced “pro say”) litigants by the same standards as a minimally competent attorney. However, they are also usually required to give pro se litigants the benefit of the doubt. This strange double standard can lead to unusual and unpredictable results.

All medical doctors owe their patients a duty of care to act reasonably under the circumstances. This means that they must act as a “reasonable doctor,” who works in the same geographical area as the defendant doctor, would act under the same or similar circumstances. Doctors who are specialists are usually held to a nationalized standard of care when it comes to medical negligence cases.

Finally, you should also report the incident to a state regulatory agency for further investigation and possible punitive action. Although many of these punishments will be less than what you may want, it still creates a paper trail that can be presented as evidence in a civil case. Doctors and nurses should be reported to their regulatory boards. State health departments are in charge of hospitals and nursing homes, so they should be contacted if the incident occurred at one of these sites.
You will first have to find out whether you have bladder cancer to see if you even have a case. If you do have cancer (and I hope that you do not) then you would need a medical expert to be willing to say that your doctor that was treating your for the UTI's failed to diagnose you as having cancer as soon as they should have diagnosed you. This is the hard part of proving this case.

While some medical errors are unavoidable, and things go wrong even when the utmost skill and care is used, doctors and other health care providers can be held legally responsible for any injuries that result from the provision of negligent or sub-standard care to patients. If you decide to file a personal injury lawsuit against a doctor, it will most likely be under a legal theory known as medical malpractice.
