I have been taking baby aspirin since I had a colon cancer scare after my doctor advised me to. After a lot of literature reading, daily low dose aspirin therapy seems to be a good way to take care of your health.
According to most general physicians here in Germany I shouldn't be taking it as a person without said medical history.
I don't plan to continue taking daily Asprin when I have met my weight loss and exercise goals.
This new evidence for benefits with cancer patients is very interesting.
Studies like that are hard to judge as a layman, meta-studies even more so.
[2] found:
> Cancer was the major contributor to the higher mortality in the aspirin group, accounting for 1.6 excess deaths per 1000 person-years. Cancer-related death occurred in 3.1% of the participants in the aspirin group and in 2.3% of those in the placebo group
In addition there's the risk of gastrointestinal bleeding.

My intuition says that excessive inflammation, mechanical wear, or other repeated injuries at any scale are cancer/death fuel.
