Colorectal Cancer Risk Reduced by Aspirin

Researchers in Scotland conducted a study in which they found low-dose aspirin used regularly can cut the risk of colorectal cancer by a third. After just one year of taking a daily dose of 75 milligrams, patients had reduced their colon cancer risk by 13 percent, the study found. After five years of taking the same daily dose, the risk was reduced by 37 percent.

Over 5,000 people participated in the study – 2,279 cases (people with bowel cancer) and 2,907 matched controls. Ages ranged from 16 to 79. All the study subjects completed questionnaires on their food choices and lifestyle traits. The bowel cancer survivors and those who developed the disease were tracked over five years.

Increased risk reduction was found in those who took more than 525 milligrams of aspirin per week. The risk reduction was found to last ten years. A relationship between aspirin use and colon cancer risk reduction had been explored by previous research, but the Scottish scientists wanted to determine if a low dosage could be effective. High dose use of aspirin can cause gastrointestinal bleeding; the Scottish research shows a high dose may not be necessary.

Colon cancer is the third leading cause of cancer in males, and fourth leading cause in females. It might be related to a Western diet which includes low-fiber and high-fat foods. (Source:

The American Cancer Society does not recommend taking aspirin to ward off colorectal cancer due to potential harmful side effects. It is not recommend to begin any medication regimen without speaking to your doctor or health practitioner.

Be very cautious taking an aspirin every day. Each year 16,000 people die from taking aspirin type over the counter drugs and many thousands are hospitalized. See the comment I placed below regarding Magnesium, much safer and more effective.
