Prayers needed for a friend

Jodi, who I went to high school with, has a sister that found a lump under her arm recently that was determined to be a rare type of tumor. After several visits to a surgeon, the tumor was removed. The pathologist determined that the tumor was a very rare type that is very agressive. This tumor also has finger-like projections that grab and wrap around organs. This tumor will also definately reoccur at sometime and could turn malignant at any time. Jodi's sister, Laura, is heading to the Mayo Clinic Minnosota to have the rest of the tumor removed by a specialist. She has 2 young sons and is in her late 20's. I am asking everyone who reads this to be praying for Laura and her family. Warren, their brother, went through all this in high school with a brain tumor. PLEASE PRAY!!! Thanks.
