The aspirin dose was not that high either - 600mg daily for 2 years.

"...Research has shown that a regular dose of aspirin reduces the long-term risk of cancer in those who are overweight in an international study of people with a family history of the disease."
"...937 people began either taking two aspirins (600 mg) every day for two years or a placebo. When they were followed up ten years later, 55 had developed bowel cancers and those who were obese were more than twice as likely to develop this cancer -- in fact 2.75 times as likely. Following up on patients who were taking two aspirins a day revealed that their risk was the same whether they were obese or not."
