Help my Dad fight Multiple Myeloma

On March 21, 2017, my Dad was simply swinging an ax to take apart a headboard, to load in his truck.  Little did he know, his bones are very weak.  One swing and his humerus snapped, in his arm.  He went to the hospital, knowing he had broken it.  They did an x-ray, and the results weren't good.  They found a lesion on his bone where the break was.  From there, they transferred him to a different hospital to perform more tests.  After a week in the hospital, they performed surgery to place rods in his arm for repair.  The day after the surgery, we got the news we were all hoping NOT to hear.  My Dad has CANCER.  Multiple Myeloma, to be exact.  Cancer of the red blood cells and bone marrow.  I am asking for help so that I can take the time off work needed to get him through his treatments.  He started 2 types of chemo, a bone strengthening injection, and radiation the beginning of this month (April).  I'm asking for help so that I can be there for my dad and take him to all his appointments.  Every appointment is 100 mile round trip.  That's 5 days a week.  Please, any little bit helps.  Thank you all in advance, for any help you may be able to provide would be a relief.
