pancreatic cancer doesn't really give you a chance. By the time they find it it's usually too late and you only have a few months. so how to detect this early ? or just pray your whole life it will not happen to u ?

you can have an ultrasound scan - speak to your GP is you are worried. The thing is to be vigilant about your health. If you are worried, then go to a doctor and ask for a referral. You can always pay to have private tests done if you can afford it and want the results back quickly.

Pancreatic cancer is really tough to detect, which is why it's detected late so often. Things like weight loss, jaundice, occasional abdominal pain, gastric outlet obstruction and new onset diabetes for no reason (you're not fat, overweight etc). Overall pan CA is very rare. Only about 2% of newly diagnosed cancers in the US is pan CA so try not to worry about it.
