Found cancer, removed uterus, and then it turned out: it was someone else's test

In the US, a 43-year-old woman underwent a hysterectomy due to a misdiagnosis of cancer, which turned out to be another patient's test. The incident occurred in 2025 at Kaiser Permanente medical center in Georgia. After the surgery, it was discovered that the tissue sample belonged to another patient. The woman filed a lawsuit for compensation. Similar cases occurred in Israel in 2014 and 2004.

In the United States, 43-year-old Cassandra Barksdale underwent surgery to completely remove her uterus, cervix, fallopian tubes, and ovaries after a biopsy mistakenly showed aggressive endometrial cancer. However, after the operation, it was discovered that the tissue sample in which cancer was found belonged to another patient. The error occurred due to careless handling of the sample at a diagnostic company before it was sent to an external laboratory. Cassandra filed a lawsuit for negligence. Kaiser Permanente admitted that the error could have been avoided and apologized. Similar cases occurred in Israel: in 2014, a woman had her breast removed, and in 2004, a woman had her uterus and ovaries removed due to erroneous tests. In Israel, strict protocols exist to prevent such errors.
