Dad’s hospital and medical bills

our family would like to ask for financial assistance for hospital and medical bills for my dad. Last 2015, we discovered a tumor on my dad's left kidney. The doctor advised us that it should be removed during that time. Unforetunately, my dad have to undergo an urgent and different operation. He underwent appendectomy. We were already having financial difficulties that is why we have to disregard first the tumor and prioritize what needs to be operated asap. A year had passed, the doctor informed us that the tumor from his kidney grew and have to be removed asap. After the operation, the doctor told us that he removed metastasis that he also noticed during the operation. Last june, my dad felt pain around his abdomen and already having a hard time moving around. Upon checking, the doctor found out that there are metastasis found at his other organs like liver, lungs, bones and muscles. This time he have to undergo tomotheraphy. Something about radiation just to ease the pain. After this, we were advised that he have to take oral medication to treat his cancer. Just last sept 9, my dad was rushed again to the hospital because he was having a hard time breathing. This time, his lungs was filled with water and have to be treated again. Up to now, he is still in the hospital because the excess fluid should be drained. Our family is already having a hard time looking and asking for financial assistance to anyone. The hospital bills are already rising from 80k to 400k and still going up. His cancer meds have to stop first because he needs to recover first before he can resume the medication. Unfortunately, we do not have any money to buy the medicine. We really appreciate any help.
