B.C. patient having continous pain in urethra & bladder that began with 1st round of chemo. My ? is, can chemo cause an inflamation of the urethra that is permamnent? I am a 58 yr. old female, had partial mastectomy 11 mo. ago, adriamycin, cytoxan chemo every 2 weeks 4 rounds, 33 rads, 9 Herceptin infusions (every21 days) that I have stopped & am struggling with whether to continue.They want a full year.(have had 7 months) Have had Ext. & int. ultrasounds of entire pelvic region& kidneys, dozens of urine & blood tests, biopsies of uterus & a cervical polyp, all negative, then finally a cysto that showed irritation/inflamation of urethra & bladder, but still not testing positive for infection.Have no discharge or itching, just pain.Was put on presc."just in case it is an infection that is not showing up on tests", Cipro,Zithromax,Doxycycline,(1 at a time)did not help, & Detrol which helped a little with night time frequency & slight diff. in level of pain.Pain is constant & is much worse after each treatment.During AC had nosebleeds, bleeding from urethra , rectum, (not profuse, just small amount) for 3-4 days after each, & mouth sores, definately irritating.as it went thru me. Had invasive ductal carcinoma, 1.5 cent.,stage 1, sentinal node biopsy negative, clear margins, Her2+ER+PR+grade was "between 2&3". In otherwise good health. Pain is affecting QOL. Will it ever go away?Has been 8 months since the AC ended, but feel the Herceptin is irritating & not allowing it to heal? Thank you for any advice.
