    Yes, there ARE false positives - Cancer News.


    Was that your question?

    My concern with some of these tests is that they leave you with more questions than you started with!

    This is a DNA test,If it is sensitive enough,if come out positive, even can not find any cancer by colonscopy but can not r/o any cancer cells inside the body.Cancer forming are first change DNA of the cell then through 1st,2nd 3 rd... mutation then became cancer cell.If the test can pickup the DNA change then even before the micro cancer cell grow will be positive.Because this people has positive test even no sign or genernal finding can not say is cancer free then can not say false positive.

    Please don't misunderstand my question.I never say there are no false positive sure must have but base my understanding it is very hard to say it is cancer free and say it is false positive,it may need many year for observation then get the conclusion.

    Again - the question was whether ANYONE has received a false positive. The answer is yes.

    The OP asked what time it is. You described how to build a watch.

    I find your posts remarkably confusing and off target. You are not talking to medical professionals. You ARE talking to people who need very specific information and/or some reassurance.
