Some families tend to get more cancers in one type of organ than another. Diabetes, dietary fat, and things that are extremely irritating to the pancreas (ciggerettes, alcohol, chemicals-industrial chemicals!, raise the risk factors). Men get pancreatic cancer at a rate many times greater than females.
The same symptoms are that of gallstones. (fatty food intolerance, epigastric pain,etc)
I think it sucks that a tabloid outed Swayze and he did not have the choice of telling the public or not telling. My greatest sympathies.
Pancreatic cancer carries a one percent survival rate, it is the deadliest and fastest spreading cancer. Often even attempting surgery increases the rate of spread.
