My blog friends, please help me pray

My sister, yes the one who has been through so much, has a tumor on her side. I am leaving right now to take her to have a cat scan done on it. Please pray for her strength during this, and also that it would be nothing serious. The doctor said it could just be a fatty tumor, and nothing serious, however it could be something worse. We are hoping for the fatty tumor option. She has lost like 140 pounds, so it is quit possible that is all it is. Thanks in advance.
