When you find out that you have cancer, your focus shifts to receiving treatments and maximizing recovery. But what happens when you discover that your advanced diagnosis could have been prevented earlier? This news can be painful to carry, and feeling angry about it is normal.
In Oregon, you can sue the doctor for their failure to diagnose the cancer early. However, it is important to understand that a strict time limit exists on holding a negligent practitioner accountable.
Filing a claim within the two-year window
Under Oregon law, you have two years to file a medical malpractice lawsuit. Usually, the clock starts on the day the mistake or omission occurred. Since cancer emerges late and may display silent symptoms, the timer does not start until the day you actually discover it or when you should have reasonably realized it. This means if a doctor missed a tumor in 2024, but you were not correctly diagnosed until 2026, your legal timeline generally begins at the time of that correct diagnosis.
Considering the absolute cutoff date
While Oregon offers a pathway to hold physicians liable, the law enforces a strict statute of repose. If more than five years have passed since the date of the initial medical error, you can no longer file a claim. For instance, if you discovered the mistake in the sixth year, this cutoff bars you from suing the healthcare provider.
Taking action to avoid complications
Oregon’s statute of limitations can be confusing to understand. If you are unsure about when you need to file a claim, seeking guidance from a medical malpractice attorney may be helpful. They can also offer insights on building a strong claim.
