Aspirin could improve survival rate for some cancer patients, according to a study by the National Cancer Institute.

Researchers with the institute say breast cancer and bladder cancer patients could prevent from taking aspirin three times per week.

They studied more than 140,000 men and women over 13 years, and each participant was 65 years old at some point.

Researchers found those with breast or bladder who took aspirin three times per week increase their survival odds by 25% through 33%.

Those who used any amount of aspirin increase their odds of survival by at least 20%.

Researchers say the anti-inflammatory impact of aspirin could be the reason it helps increase survival rates.
