Medical Bills ; cancer treatment; surgery

My mother, Betty Miranda has been diagnosed with stage 4 pancreatic cancer: This is after they diagnosed her with diabetes, removed her gal bladder and have run miltipil tests and xrays.  She only has medicare and they cover about 75% of her bills, but thats not counting the trips, the gas, some prescriptions are not even covered. Her chemo alone is eating them alive not counting all the extra pain meds and prescriptions. I am sparing everything I can and it simply isnt enough.
       My mother and father are some of the kindest people you could meet, this disease is costing them everything they own, I am reaching out to help them pay off this medical debt.
