Studies have shown that taking aspirin lowers the risk of colorectal cancer and the risk of death from colorectal cancer. The decrease in risk begins 10 to 20 years after patients start taking aspirin.
Always consult with your physician before taking any medicine or supplement as there are potential risks involved. Generally, you will take a low-dose aspirin (100 mg or less) every day.
The possible harms of aspirin use (100 mg or less) daily or every other day include an increased risk of stroke and bleeding in the stomach and intestines. These risks may be greater among the elderly, men, and those with conditions linked to a higher than normal risk of bleeding.
Other common side effects can include rashes, abdominal pain, hives, heartburn, asthma, headache, cramps, upset stomach, and stomach ulcers.
