Mum told me to keep it a secret
My dad has stage 4 cancer
Last year he had bladder cancer which was apparently aggressive , and apparently it was treated
I just got told today but 3 weeks ago my dad got told that he has cancer in his lymph nodes, lung, kidney and renal gland, my mum always lies and told me that "it's all early and looking good" which I think is bullshit he's having a pet scan
Last year when he had bladder cancer she told me I can't tell anyone, which means my 2 sisters
Now I don't believe her that it's not serious she told me that dad said no matter what don't tell me ( I'm going through alot of hard things) but mum told me "incase it gets worse or bad"
I don't know what to do, if it's travelled into the lungs then I'm pretty sure he's terminal, I want to tell my sisters as he may decline quickly but I don't want them to hate mum more
Mum has pancreatitis and has proteins leaking from her kidney due to smoking, drinking and being over weight, she has her Gaul bladder removed and she's still eating unhealthy smoking and drinking ( although lying about it since she calls drunk) , I'm worried that if I go against mums wishes they will hate her and she may also die soon
I really don't know what to do
