Can Radiation For Cancer Cause Excessive Vaginal Discharge?

just had a ct scan with contrast done because I was having a problem with excessive vaginal discharge. I also had a hysterectomy done in December 2013 stage 1b cancer. the results of ct scan showed a mild diffuse bladder wall thickening. please correlate clinically result. I also had radiation done externally 25 treatments in march & april & had 3 internal radiation done also in april? did the radiation cause this problem?
