Help Robert Martinsen with medical bills

In 2014 and 2015 Bob had lung cancer 2 times and went through 38 chemo and radiation treatments and went into remission. Then a year and half ago he had bladder cancer, had chemo twice for that and was cancer free. Now this time he really needs help. He was diagnosed with 2 different cancers. One is tongue cancer and the other is lymph node cancer. He couldn't be in Duluth for treatment on where the cancer is located, they are sending him to the Mayo in Rochester for treatment. Bob and Pat were at the mayo for 4 days with so many tests, his testing started at 7 am and didn't end until about 4 or 5 pm. He has more tests on September 28th and 29th. October 1st he has surgery and after that will be in rehab and having chemo and radiation treatments for approximately 5 to 6 weeks in Rochester. We are asking for help for the expenses for housing and medical bills. If anyone is able to help it would be greatly appreciated. Positive thoughts and Prayers would also be welcomed. We also have a donation account set up through the North Shore Federal Credit Union.
