HELP my Son with Medical Expense for Cancer

Please help my son! He’s a single dad and this news could not come at a worse time with work being slow during this pandemic. He’s been diagnosed with Testicular Cancer.  He has a MAJOR medical plan with a $5000 deductible. Many hands make the load light.  He’s only 29 years old and facing this horrific disease so any help will be much appreciated!  Please share!
