Advice, please, re bleeding.

The worse thing for me about having breast cancer is that now when anything else happens that I would have taken lightly I think "cancer." I hope a day will come when I can stop doing this.

Anyway, yesterday, I had bleeding after urinating, noticeable bleeding, and immediately thought bladder or kidney cancer. I took some Uristat last night and it seems to be better--no bleeding and just a little burning, so it probably is a urinary tract infection (UTI) although the symptoms seem somewhat different from past incidences of UTI--less severe. Has anyone out there had this problem; I'm still on herceptin but nothing else at the moment other than normal drugs: high blood pressure, thyroid, reflux, and one baby aspirin. Thanks.
