How aspirin fights colorectal cancer
Taking aspirin reduces a person's risk of colorectal cancer, but the molecular mechanisms involved have remained unknown until a recent discovery. discovered that aspirin might exert its chemopreventive activity against colorectal cancer, at least partially, by normalizing the expression of epidermal growth factor receptor (EGFR) in gastrointestinal precancerous lesions. EGFR is overexpressed in about 80 percent of cases involving colorectal cancer, the third-leading cause of cancer-related death in the United States.
