blood in urine?

[pilgrim37]

Hi all:

I'm a year out from my last herceptin treatment (had stage III her2+, 3 months taxol/herceptin, bilateral mastectomy, 3 months A/C, 6 weeks radiation, balance of year on herceptin). Had complete response and was ecstatic.
Just returned from what was supposed to be routine annual obgyn appt & urine test showed microscopic blood in the urine. She said it could be caused by bladder cancer (& also many other things) -- tests pending. I'm scared. Looked up her2+ bladder cancer, & it's not good. Of course, if it's a recurrence, I'd be stage IV. Anyone had mets to the bladder? I'm ahead of myself b/c haven't been diagnosed with anything other than microscopic blood in urine, but just thought I would ask...
