Maybe you should ask a real doctor. Right now you're just going to get people who play doctor on the internet.
Some believe the results, some are just waiting for a more definitive study.
In the end one doctor said "..not to take it even if it has SOME benefits. Aspirin, like any other pill can cause gastrointestinal bleeding. So if there is no reason to take it avoid it..."
A pill, after all, is just a transport mechanism. It's the substance of the pill that determines side effects and risk. For example, you don't often hear about multivitamins causing stomach bleeding.
This is truly a balancing act, and we really don't know enough to balance it for generally-healthy people at large.
