Question
At a local hospital’s gynecological free clinic, many people had tests done, and one of my friends later had several more. The result of the immunohistochemistry was CK7+, does this mean they have cancer?
Answer
I’m happy to answer your question: CK stands for cytokeratin, and CK7 is one of the immunohistochemical tests, which is positive for ovarian, lung, and breast cancers, but negative for colorectal, prostate, and gastrointestinal cancers. Therefore, if a patient has this test result, it should be taken very seriously. It’s recommended to go to a top-tier hospital for further examination. I hope my response is helpful to you.
