Please pray for identical twins BRCA2 positive

My name is Heather and I am a breast cancer survivor, BRCA 2 positive with an identical twin, who is also BRCA 2 positive.  I was diagnosed in October 2008 and successfully went through tx and am now cancer free.  My twin sister was diagnosed six months later with a type of ampullary cancer.  She had the whipple procedure in August 2009 with a good outcome and then two months later--she was diagnosed with mets to the liver.  This has been a horrible year and I never could have imagined that we both would have been diagnosed with different types of cancer.  I responded wonderfully to treatment and chemo, but it has been horrendous for my sister.  She has lost 100 pounds and is only a shell of the person that she used to be.  I sincerely believe that there is so much connection with the BRCA gene and family history.  Our mother had breast cancer twice and then died from ovarian cancer.  My paternal grandmother died from pancreatic cancer and then my dad died from liver cancer.  I have a strong family hx and I dont even usually like to tell my story because of people's reactions.  My sister's treatment and chemo has been hell.  Her first chemo regimen the doctors said--was not working--so now the cancer is spreading.  They have given her a few months to live and I hope they are wrong.  She has two small children and I cant imagine life without her.  Please pray for us. Cancer sucks and I just wish there was a cure.  When this all started, she cried and told me that she wished she had been diagnosed with breast cancer.  What a horrible thing to have to make a choice on any type of cancer.  I PRAY EVERY DAY FOR HER AND I DONT CLAIM THIS CANCER IN THE NAME OF GOD.  PLEASE PASS THIS ON TO ALL YOU KNOW--HER NAME IS KATHY AHMED.  Thanks and bless us all, heather
