Nursing home rang today. Father, late 90s, has tested positive for Covid (5 weeks ago) but asymptomatic apart from fatigue. Has just had blood test results - his long-term anemia has worsened, and some of the bloods "suggest cancer". I have to decide how far they should investigate. My father doesn't have capacity for this decision.
The complicating factor is my father is adamant that he wants to live as long as possible, with every attempt made to save his life. So really I'm being asked "how much suffering do I want to inflict on him to prolong his life"
I'm going to talk to the doctor. I need to know what type of cancer could cause this anemia, what at his age they could do about it, what difference would investigating make to the treatment he would have. Anything else that it would be useful for me to ask?
