Lena,
I know you must be anxious and frightened when there are so many "unknowns" but I agree with Mike, it's best if you can somehow calm yourself. You were smart to find this website and information is power...keep that thought in mind and it will help you with making some tough decisions.
My first real and strongest fear came when I found blood in my urine on 2/14/07; I had been having issues with frequency, urgency, and pressure for a few weeks prior. Not long afterwards I had a cysto done and when the doctor asked if I wanted to look at the monitor, I saw a red, nasty looking piece of cauliflower looking tissue where I knew my bladder was suppose to be pink...I knew it was cancer. This past July I celebrated three years of being cancer free, after doing chemo and having had my bladder removed and an Indy Pouch made. I feel very blessed and if your mother needs treatment, I wish your mom the same blessings in her futue.
You may want to check my website for info., link located below my name; I got an Indy at age 56 but there is some info. about the Ileal on there also.
