What assistance can my elderly parents get for daily upkeep of their home?

Mother is 78 has stage 4 cancer and is currently undergoing chemo treatments. She has been fighting cancer for over 8 years. This last round is leaving her very week, can not do the daily care for her home and my father. My father is 84 and is crippled and is in constant pain, incontinent & a diabetic. He is under doctors care. He no longer can help around the house and is having difficulty maintaining his hygiene.
