For years, women have been told that early detection of cancer saves lives. Not always. A definitive new study finds that screening healthy women for ovarian cancer — one of the deadliest and most-feared of malignancies — actually does more harm than good.
In an 18-year study of 78,216 women, those randomly assigned to be screened for ovarian cancer died at the same rate as women who weren't, according to research released Wednesday in advance of the annual meeting of the American Society of Clinical Oncology.
Tests for ovarian cancer can backfire
Coffee drinking may cut prostate cancer risk
In case you needed one, here’s another possible reason to have that cup of coffee in the morning: Men who regularly drink coffee appear to be less likely to be diagnosed with prostate cancer, especially the most lethal kind, according to new research.
Lorelei Mucci of the Harvard School of Public Health and colleagues analyzed data collected from 47,911 U.S. men who participated in the Health Professionals Follow-up Study, a large, ongoing examination of a variety of health issues for men. As part of the study, the men reported their coffee consumption every four years between 1986 and 2008. During that period, 5,035 cases of prostate cancer were reported, including 642 fatal cases.
Doctors examine AIDS 'cure' case
Doctors say a 45-year-old man in California may be the first person ever cured of AIDS as a result of the discovery of an apparent HIV immunity gene.
Timothy Ray Brown tested positive for the human immunodeficiency virus in 1995, but has entered scientific journals as the first person to have that HIV virus completely eliminated from his body in what doctors have termed a "functional cure," KCBS-TV, San Francisco, reported Monday.
Produce industry presses USDA on pesticide report
Every year for two decades, the U.S. Department of Agriculture has issued an annual report on the amount of pesticide residue it detects from samples of fresh fruits and vegetables around the country.
The Environmental Protection Agency uses the data to monitor exposure to pesticides and enforce federal standards designed to protect infants, children and other vulnerable people. But the 200-page annual report has become a target of an unusual lobbying campaign by the produce industry, which worries that the data are being misinterpreted by the public.
FDA approves boceprevir, the first new hepatitis C drug in 20 years
The Food and Drug Administration on Friday approved marketing of the Merck drug boceprevir, the first new drug for hepatitis C in 20 years. The agency is still considering approval of a similar drug, telaprevir, and is expected to approve it soon as well. Both drugs are members of a new class of hepatitis drugs called protease inhibitors, which block a key enzyme required by the virus to replicate.
They are expected to convert hepatitis C from a debilitating disease into a manageable condition for the majority of people infected with the virus. Boceprevir, which will be marketed by Merck under the brand name Victrelis, is approved only for use in conjunction with the current hepatitis C drugs, peginterferon-alpha and ribavirin.
Marijuana cuts lung cancer tumor growth in half, Harvard study shows
The active ingredient in marijuana cuts tumor growth in common lung cancer in half and significantly reduces the ability of the cancer to spread, say researchers at Harvard University who tested the chemical in both lab and mouse studies.
They say this is the first set of experiments to show that the compound, Delta-tetrahydrocannabinol (THC), inhibits EGF-induced growth and migration in epidermal growth factor receptor (EGFR) expressing non-small cell lung cancer cell lines. Lung cancers that over-express EGFR are usually highly aggressive and resistant to chemotherapy.
Anti-retroviral drugs 'help reduce' HIV transmission
An HIV-positive person who takes anti-retroviral drugs after diagnosis, rather than when their health declines, can cut the risk of spreading the virus to uninfected partners by 96%, according to a study.
The United States National Institutes of Health sampled 1,763 couples in which one partner was infected by HIV. It was abandoned four years early as the trial was so successful. The World Health Organization said it was a "crucial development".
