Health Notes:
A look at the latest medical studies and trends
Two tests endorsed to detect colorectal cancer
The American Cancer Society and other health groups are endorsing two tests to detect or prevent colorectal cancer. The new policy is based on evidence that the tests work well enough to recommend, and may be more amenable to some patients than more invasive tests. One test is virtual colonoscopy, which uses a CT scan to look for abnormal growths, and unlike the standard colonoscopy, does not require inserting a camera-tipped tube rectally. The other test examines stool to find abnormal DNA associated with cancer.
New study examines risks after stopping hormones
A new study shows that when a woman stops taking hormones prescribed for menopause most of the benefits disappear, but a slightly higher risk for breast and other cancers persists for at least three years. The data comes from a major study by the Women’s Health Initiative that looked at 16,000 women who used the estrogen and progestin combination drug Prempro, made by Wyeth. Researchers urge caution in interpreting the results, noting that a woman’s individual risk remains small. The findings do not change recommendations for hormone use – they should be considered only if a person is having moderate to severe hot flashes and other symptoms, and only at the lowest dose and shortest period of time.
