Mike's Bone Marrow Transplant Expenses

In 2015, Mike, my grandpa, was diagnosed with Multiple Melanoma. This is a cancer of the bones. It softens and destroys all of the bones in the body, which is extremely painful.  
Mike has went through many years of chemotherapy, radiation, and already one bone marrow transplant.  These treatments are very expensive, and Mike is already in need of another bone marrow transplant. He has to go Rochester, Minnesota to get this procedure done. While his bone marrow transplant is taking place, Mike and  his wife Tammy, will need to be in Rochester away from their home in Northern Wisconsin for 1 1/2 months. Tammy will be unable to work during this hard time. 
We are asking for money to help them through this hard time and to help cover some of his medical expenses.
