    test positive for

    Hi, I was reading an English article about throat cancer and I found this sentence:
    "those tumours that tested positive for the strain"
    I did not understand what those tumours do..... in other words?
    Could you please help me?
    thanks a lot!

    Re: test positive for

    The tumours did nothing.

    A small piece of tumour tissue was removed and sent to a laboratory where it was tested to establish if cancer cells existed.

    To explain a bit further: the results of test to determine whether that strain [strain: Information from Answers.com] existed in the tumour were positive. When the results of a test to show the existence of something are positive, it's normal to abbreviate this to 'it tested positive for [thing-sought]'.

    PS You can hear this in any episode of CSI (usually several times); things on that show are always 'testing positive for blood'.

    Re: test positive for

    Usually in the case of tumors, they are described as either "malignant" (cancerous) or "benign" (harmless). When a tumor is removed and sent to the pathology laboratory to be checked for disease, this is called a biopsy. In the case you described, it would seem more natural for the doctor to say something like "The biopsy showed a malignancy" rather than "tested positive for cancer." I'm wondering if the article you read was referring to the biopsy testing positive for a certain strain of HPV (human papillomavirus), which is known to cause cervical cancer and has also recently been linked to throat cancer.
