Very sorry for your loss but there is a monumemental difference between now and 1985. Unfortunately it sounds like you guys had an Oncologist who made promises he/she shouldnt have. But living 10 years on metastatic cancer in 1985 is actually phenominal. Be thankful for what they gave you and stop blaming them for what you think they took. Fact of the matter is Oncologists gave you 10 years with your Dad.
