Part of the problem is that most (or all) of those symptoms can be anything from, well, indigestion or constipation to ... you know what. And other cancers can have completely different symptoms, also apparently innocuous, and yet if ignored, deadly.
We have to try to strike a balance between not rushing to the GP or A&E every time we belch or a curry causes ... ummm, irregular 'movements'
but not ignoring persistent if seemingly trivial issues either. If it seems to not go away, over a period (the video says 4 weeks)
get checked.
Also, I've said before, if you get offered a screening program (I got one for bowel cancer a year or so ago), then (
IMHO) the mindset that says "I'm busy at the moment, I'll get around to it" is idiotic and could cost you your life.
I know this is about pancreatic cancer, and I don't want to detract from that but the same logic, with differing symptoms, applies to other cancers too. No need to panic and always assume the worst, but persistent and unusual symptoms? It
might be serious. Very serious. Get checked.
