Please help our dad

Hello, My name is Wendy.  I am writing this in hopes of helping  my father.  So a little back story.  Last year my dad was diagnosed with prostate cancer.  After successful treatment  he was in remission. Unfortunately, we recently found out that the  cancer returned . He is currently getting radiation treatment.  This has been a long  and stressful road for him and our family. He has always been self employed working as a master craftsman building homes . Although he has insurance, the medical expenses and copays for multiple doctors and specialist are expensive. Since the diagnosis he has only been able to work  limited hours daily due  to the daily radiation treatment which causes fatigue afterwards.   We are hoping to get him some relief and help cover his medical expenses and mortgage to take the stress off of him and allow him to recover without worrying about the next few months of not working.  He truly is one of the kindest men I have ever known. He has always helped  others at church, home, and at times complete  strangers . We are hoping  to repay him for the  great help he has been to others . Please if anyone can help,  it would be greatly appreciated.
