Prayers you and your family. I know what you are going through,my aunt who decided to raise me after my mother ran out passed away last February from small cell lung cancer but had beat Non Hodgkin's Lymphoma just 3 years before the SCLC was a crazy ball out f left field wasn't much the doctors could do but make her comfortable because radiation had no effect. I know its not the same as losing a father just letting you know there are others here for support if you need it.
