A new study finds that long-term aspirin use before a diagnosis of colorectal cancer (CRC) may be associated with lower CRC-specific mortality. The report that appears in JNCI: The Journal of the National Cancer Institute, suggests that the findings for pre-diagnosis aspirin use might help reduce CRC mortality in the overall population by limiting metastatic spread of colorectal tumors before diagnosis. Preventing distant metastases leads to fewer deaths from colorectal cancer.
