Hi Damamma,
Welcome to the site although I am sorry that you had to find us. And I am sorry to hear of your sisters diagnosis. My dad was diagnosed in the summer of 2008 and his CC was deemed inoperable. His treatment was Photodynamic Therapy with the possibility of chemo to come, but he never had chemo. Has your sister spoke with her doctors about the possibility of other treatments such as radiation, PDT or Cyberknife?
Please feel free to ask any and all questions that you will have and I am sure that someone here will be able to help. At the top of the page there is a search function that you can use to look for postings on any topic and this will hopefully be of some use to you. I hope that you will keep coming back as you will get a load of support and help from us all.
My best wishes to you and your sister,
Gavin
