In February 2021, a 45-year-old Philadelphia woman named Isis Spencer went to Lankenau Medical Center for a biopsy. She had no symptoms. She felt fine. She was just following up on a concern her doctor had flagged.
Then she got the call that changed everything: she had cancer. Grade 2-3 endometrial cancer, they told her — cancer in the lining of her uterus.
Within weeks, her uterus was gone.
And then she found out she never had cancer at all.
One of the largest medical mistake verdicts in recent Pennsylvania history, covering damages against Main Line Health (through a prior private settlement) and a jury award of $12.25 million against Penn Medicine and the treating physician.
What Went Wrong at the Lab
The problem started with Spencer's biopsy slides at Main Line Health's Lankenau Medical Center. Lab work involves taking tiny tissue samples, placing them on glass slides, and examining them under a microscope. When slides get contaminated — meaning tissue from one patient ends up mixed in with another patient's sample — the results can be completely wrong.
That is what happened to Spencer. Her slides had been contaminated with someone else's tissue. That other tissue showed cancer. So the lab report said Spencer had cancer — when in fact, her own tissue was perfectly healthy.
She had no idea. No one told her the lab had made an error. Instead, she got a cancer diagnosis.
A Second Opinion That Should Have Stopped Everything
Spencer did the right thing. She sought a second opinion at Penn Medicine, one of the top hospital systems in the country.
A doctor there, gynecological oncologist Janos Tanyi, ran more tests — including another biopsy. According to Spencer's court complaint, that biopsy came back negative for cancer. Other tests also came back negative.
But Spencer says she was never told those results were clear. Instead, she was encouraged to move forward with surgery.
On March 8, 2021, Spencer underwent a total hysterectomy — the complete surgical removal of her uterus.
After the surgery, Penn Medicine's own lab examined the tissue that had been removed. Their finding: no cancer. Not a single cancer cell.
Spencer had lost her uterus because of someone else's tissue on a contaminated lab slide.
The Real Cost: More Than a Verdict
Losing your uterus is not just a surgical outcome. For Spencer, the surgery triggered sudden early menopause. She described symptoms including dizziness, nausea, and severe headaches. And beyond the physical effects, she had spent weeks believing she had advanced cancer — going through the fear, the grief, and the life-altering decisions that come with that kind of diagnosis.
The jury recognized the full weight of what she lost.
How the $35 Million Was Divided
Reached a private settlement with Spencer in 2022 — before the trial began — for contaminating the biopsy slides.
The jury assigned 35% of the remaining verdict — $12.25 million — for going ahead with surgery even after their own tests showed no cancer. Penn Medicine has announced plans to appeal.
What This Case Tells Us
This case is a clear example of how one mistake in a lab can set off a chain of decisions — each one relying on the last — that leads a healthy person into surgery they did not need.
Labs contaminate slides. Doctors sometimes push forward with treatment without sharing all of the information. And patients, already scared, often trust that the medical team has their facts right.
This case shows that hospitals and labs can be held responsible when their errors cause real harm. You do not have to simply accept what happened to you.
What to Do If You Think a Doctor or Hospital Made a Mistake
If you — or someone you love — had surgery, lost an organ, or went through cancer treatment and later found out the original diagnosis may have been wrong, it is worth talking to someone who handles these kinds of cases.
Other warning signs to look for:
-
A second opinion gave you a very different result than the first
-
A doctor told you test results were one thing, but you later learned otherwise
-
You had a procedure and the removed tissue came back showing nothing wrong
-
Your symptoms never matched the diagnosis you were given
You do not have to figure out on your own whether something went wrong. That is what a free conversation is for.
