I Have Ovarian Cancer. My Recent CT Scan Shows That

I have ovarian cancer. my recent CT scan shows that a tumor located low in the pelvis is pressing agains my bladder. I have to frequently run to the bathroom where I urinate a small amount of urine. My creatine count is a 5 so we did not do chemo today. we have opted to do give me 42 oz of fluids and then check my creatine on Thursdasy in hopes of giving me my carbolplatin chemo. Have you heard of a tumor pressing on the blader having this impact on urination?
