For seven months, Cassandra Barksdale believed she was fighting for her life. What she did not know was that the cancer diagnosis came from a medical error involving another patient’s tissue sample.
Barksdale, a 43-year-old Georgia woman, recently filed a lawsuit against Kaiser Permanente after she says a tissue-labeling mistake resulted in doctors diagnosing her with an aggressive form of endometrial uterine cancer, according to court records. The lawsuit also states that the diagnose led to a full hysterectomy, an irreversible procedure that she never needed.
The physical consequences were only part of the damage. For months, Barksdale lived with the belief that she didn’t have much time to live. She said the diagnosis, she thought she had, mentally affected her and her sons, who were forced to confront the possibility of losing their mother.
“I even started making funeral plans with them to let them know, you know, if I don’t make it out, this is what I want done,” Barksdale said.
Seven Months of Believing She Was Dying
Barksdale initially went to Kaiser Permanente Southwood Medical Center in Jonesboro, Georgia, seeking treatment for heavy bleeding and fibroids in January 2025. Fibroids are noncancerous growths that can develop in and around the uterus.
She underwent a biopsy on March 10, 2025, and was informed days later that the results indicated an aggressive form of endometrial cancer. Believing the diagnosis was hers, Barksdale prepared herself and her family for what she thought could be a battle for her life.
On May 15, 2025, she underwent a full hysterectomy, as per the doctor’s recommendations. According to the lawsuit, she was also told she would receive instructions regarding chemotherapy.
At that point, Barksdale was not simply dealing with a diagnosis on paper. She had undergone major surgery and was preparing herself mentally and emotionally for cancer treatment.
Then came the revelation that changed everything.
The Diagnosis Allegedly Belonged to Someone Else
According to the lawsuit, DNA testing in September 2025 determined that the tissue sample showing aggressive cancer did not belong to Barksdale. It allegedly belonged to another patient.
The discovery meant that Barksdale had spent months in a mental prison and unnecessary physical battle, believing she had cancer based on a tissue sample that was not hers.
Her attorney say the error had a devastating domino effect.
“She came into Kaiser Permanente looking for answers, and she left with a diagnosis that did not belong to her,” Attorney Shannan Young said.
“And every step that was taken after that was based off of misinformation.”
The Human Cost of a Medical Error
Mistakes happen, but medical errors, especially in this situation that can impact a person’s livelihood are particularly dangerous and shouldn’t be taken lightly either, as they can lead to serious consequences.
For Barksdale, the alleged error cost her a chance to possibly have more children. The circumstances surrounding the other patient remain unclear. Because of medical privacy laws, information about the other woman, including whether she received the correct diagnosis, what treatment she may have received, or whether her care was delayed, is not publicly available. For scenario purposes, the other patient missed crucial treatment for seven months last year while believing she was fine. That uncertainty makes the mix-up particularly troubling.
Kaiser Permanente Acknowledges the Incident
Kaiser Permanente has acknowledged that Barksdale should not have experienced what happened.
In a statement, representatives said the organization has highly trained staff and processes intended to prevent errors of this nature.
The healthcare provider also said it took immediate steps after the incident to prevent a similar mistake from happening again.
Kaiser Permanente said it recognizes the impact of the incident and is committed to working with Barksdale and her attorneys toward what it described as a fair and accountable resolution.
More Than a Diagnosis
Barksdale’s lawsuit serves as a lesson about the consequences that can arise from a laboratory or labeling error regarding one’s livelihood. For seven months, her misdiagnosed cancer felt like a prison sentence, leading to a mental battle that shaped the reality her family believed they were living.
Now, her lawsuit is seeking accountability and raising questions about how a mistake involving something as fundamental as identifying a patient’s tissue could lead to such profound consequences.
“I want accountability, and I also want what happened to me; I don’t want it to happen to no one else,” Cassandra Barksdale said.
A diagnosis can determine the treatment a person receives, the decisions they make, and how they see their future. In Barksdale’s case, she alleges that a diagnosis that did not belong to her changed all three.
The lawsuit remains ongoing, and the allegations have not been proven in court.
