Aspirin slows spread of colon, pancreatic cancer in tumor ce
Platelets are blood cells involved with clotting. They promote the growth of cancerous cells by releasing growth factors and increasing the response of certain proteins that regulate tumor cell development (oncoproteins). Low doses of aspirin, an anti-platelet drug, have been shown to reduce the risk of some types of gastrointestinal cancers, but the process by which aspirin hampers tumor growth has been unclear. "The current study was designed to determine the effect of inhibition of platelet activation and function by aspirin therapy on colon and pancreatic cancer cell proliferation," the researchers wrote....
