Same here my partners dad died from not going it was too late when he finally went we lost him 2 months later so my children never got to know their Grandad. The same happend with my Grandad he was still young too.
I say to my partner if you are ill make sure you go please, he never goes unless he really has to.
I keep meaning to go myself as I have a couple dodgy looking moles, I should take my own advice.
I wish you and your family well at this sad time and thank you for making people more aware, while suffering your self.
