    Choice A is wrong because PSA is for prostate cancer. Unless the breast contain prostatic tissues by some ectopic processes, I don't see why this should be the answer.

    CA 125 is good for ovarian CA

    alpha-fetoprotein is good for germ cells CA and hepatomas

    CA 19-9 is for biliary duct CA

    So my guess is D. CA 27.29 is good marker for breast CA. CA 15-3 is another marker for breast cancer.

    Here is an article on CA markers http://www.asco.org/ac/1,1003,_18-00...,00.asp?state=

    It took me an hour to look this up!
