The study examined the relationship between aspirin use and the development of pancreatic cancer. The study included 88,378 women over a 18 year period.
The study found:
(a) Women who took 2 or more standard aspirin tablets per week had a 20% increased risk of pancreatic cancer compared to women who took fewer than 2 aspirins per week.
(b) Compared to women that have never had aspirin;
(i) women who had 1-3 tablets a week had an 11% increase in pancreatic cancer
(ii) women who had 4-6 tablets a week had an 29% increase in pancreatic cancer
(iii) women who had 7-13 tablets a week had an 41% increase in pancreatic cancer
(iv) women who had over 14 tablets a week had an 86% increase in pancreatic cancer
(c) Women who reported more than 20 years of regular aspirin use had a 58% increased risk of pancreatic cancer.
The study shows that regular aspirin use is associated with a significantly increased risk of pancreatic cancer among women.
