New research in the International Journal of Clinical Practice suggests non-steroidal anti-inflammatory drugs such as aspirin may cut the risk of developing the disease by 20 percent.
Another report also looks at aspirin's possible cancer-fighting ability when combined with an experimental anti-clotting drug. Research in the Journal of Cellular Biochemistry says the drug combo slowed the growth and spread of breast and melanoma tumors.
Scientists think aspirin inactivates platelets in the blood. Platelets shelter and feed tumor cells, which can make it easier for cancer to spread.
