New research suggests that aspirin use may lower the risk of colon cancer.
The earliest forms of aspirin were discovered centuries ago. Originally, aspirin was used as a pain reliever. In 1989, researchers at Brigham and Women’s Hospital (BWH) published the results of the Physician’s Health Study, which found that aspirin also helped prevent heart attacks. Now, nearly 25 years later, researchers at Brigham and Women’s Hospital have published new research suggesting that aspirin may have another use – lowering the risk of colon cancer.
Using data from the Women’s Health Study, a team of researchers led by Dr. Nancy Cook, BWH Division of Preventive Medicine, analyzed data collected from roughly 40,000 women aged 45 years or older. Approximately half of the women studied received low-dose (100 mg) aspirin every other day for ten years. The other half of the study participants received a placebo or inactive pill. Researchers continued to gather data from women who agreed to follow up for 18 years. At the end of the ten-year study period, there was no difference between the two groups in terms of overall cancer rates. However, at the end of the 18-year follow-up period, those women who had taken low-dose aspirin had a 21 percent lower rate of colorectal cancer versus those who had taken the placebo. The study did not find any differences in the occurrence of other cancer types or cancer deaths between the two groups.
Should you get a prostate cancer screening? It depends on who you ask or what you read.
While one research study shows that the benefit of prostate cancer screening is significant, another study finds little, if any, benefit. And while one expert defends the prostate-specific antigen (PSA) screening test – which measures levels of the PSA protein in the blood – another just as passionately dismisses it. With studies, experts, and news stories disseminating such widely varying viewpoints, it’s easy to understand why men and their loved ones would feel confused – and wonder how to arrive at an informed decision.
Start by asking an expert.
Dr. Anthony D’Amico, Professor and Chief of Genitourinary Radiation Oncology at Brigham and Women’s Hospital and Chief of the Prostate Cancer Radiation Oncology Service at Dana-Farber/Brigham and Women’s Cancer Center, has been treating prostate cancer for more than 20 years and continues to be a firm advocate of prostate cancer screening, particularly for younger men. “PSA screening is effective in decreasing cancer death,” says D’Amico. “It’s a critical tool for having an informed conversation with a man about whether he needs treatment or not.”
