Hi there, my heart truly goes out to you and I will lift you and your parents up in prayer. My sweet mom ( a very young 70 ) was diagnosed with bile duct cancer on 10/2/06. She just passed away and went to be with the Lord this past Sun. April 1st. She did rounds of chemo but it got to the point where nothing else would help as the tumors were growing even with chemo. I feel your pain as I am the same age as you and can truly relate to your saddness. I have spent the past 6 months grieving my mom's illness and possible future which was cut shorter than we ever thought. In the end we were all together as she wished and it was amazing. Hospice is awesome too.
I also want to encourage you, I realize the above information is sad and you do want some reality. Most cases found late like my mom's the patient lives a few months to 13 months. BUT I do want to encourage you, my parents became friends with a couple their same age from chemo and the lady was a 5 year survivor of bile duct cancer...so as some of the other people wrote we never know what God will do. God is faithful and has a plan for all of our lives. Even in the midst of this deep, dark storm I am going through I feel GOd's presence like never before. I pray your mom is one that beats the odds with all my heart I pray that for you. You will get through this, spend lots of time with your mom. After she was diagnosed I committed to spending every weekend with her and oh, am I ever thankful I did that, I have no regrets!!! My heart breaks for my dad, they just celebrated their 50th wedding anniv. last June. God bless you my friend and I PRAY for healing.
