Study finds possible heart risk with prostate drug The Associated Press via The New York Times Share     Full results of a big study testing a drug for preventing prostate cancer show a higher risk of heart failure, a surprise finding that could dampen enthusiasm for expanding its use. On March 29, GlaxoSmithKline PLC asked the federal Food and Drug Administration to approve its drug Avodart as a cancer preventive for men at higher-than-normal risk of the disease. The drug already is sold for urinary problems, and no heart failure risks have been seen with that use, doctors say. More
Research raises hope for new head, neck cancer therapies Examiner Share
 Scientists at the Emory Winship Cancer Institute in Atlanta say they've documented how a specific enzyme dubbed RSK2 (ribosomal S6 kinase 2) promotes tumor invasion and metastasis in head and neck cancers. A cancer drug, known as fmk, which was developed at the University of California in San Francisco, is known to specifically hone in on RSK2 in certain cancer cells. So the Emory research
raises the possibility that fmk, or another compound that targets RSK2, might turn out to be an effective treatment for head and neck cancers.

UK study finds breast screen programs save lives Reuters Share
Regular mammographic screening for breast cancer saves the lives of two women for every one who is given unnecessary treatment, scientists said March 31 in a study that adds to a global row regarding screening programs. The British researchers said their work, which contradicts some recent studies on screening programs but confirms others, showed the benefits outweigh the harm screening can cause by picking up tumors that would not have presented a problem. More Report: Thyroid cancer radiation a public threat USA Today Share
A Nuclear Regulatory Commission rule allowing hospitals to discharge radioactive thyroid cancer patients to their homes and hotels poses a public health threat, a congressional report says. The House Subcommittee on Energy and the Environment, which oversees the commission, also found that insurers routinely use the rule to deny hospital care even to patients whom doctors say may pose a radiation risk to others.

HIV drugs could have second life as treatment for retrovirus correlated with prostate cancer Scientific American Share
Some medications already being used to treat HIV appear to inhibit a retrovirus that has been linked to prostate cancer and chronic fatigue syndrome, reports a new study published online April 1 in PLoS ONE. Like HIV, XMRV (xenotropic murine leukemia virus-related virus) is a retrovirus that infects host cells with its RNA through reverse transcriptase enzymes, using protease enzymes to process proteins for viral assembly and integrase enzymes to help infect the host cell's DNA. Many of the drugs approved to treat HIV target one of these processes to slow or prevent host cells from becoming infected. More DNA testing emerges as weapon against cancer Reuters via MSNBC Share
Francis Collins, who helped map the human genome, did not get around to having his own genes analyzed until last summer. And he was surprised by what he learned. Collins has a predisposition for type-2 diabetes, something he never had suspected. The lanky, former director of the National Human Genome Research Institute discovered this through tests offered by Navigenics, 23andMe and DecodeMe -- companies that charge customers a few hundred dollars for a peek at their genetic makeup. More Link between oral sex, mouth cancer discovered redOrbit Share
Researchers from the Institute of Head and Neck Studies and Education at England's University Hospital Coventry have discovered a possible link between oral sex and an increase in mouth cancer. The study, prepared by lead author Hisham Mehanna and published in the British Medical Journal, has discovered a link between the increase of oropharyngeal squamous cell carcinoma and the sexually transmitted human papillomavirus.

More women urged to get radiation after mastectomy HealthDay News via BusinessWeek Share
Women who have a mastectomy for breast cancer are less likely to receive follow-up radiation therapy than those who have a lumpectomy, even if the treatment would be potentially lifesaving, a new study has found. Researchers from the University of Michigan Comprehensive Cancer Center analyzed information on 2,260 Los Angeles and Detroit women with breast cancer, using medical guidelines to assess whether they would be strong candidates for radiation therapy because, for instance, they had particularly large tumors or cancer in four or more nearby lymph nodes. More Study links chemical exposure to breast cancer Reuters Share
Exposure to certain chemicals and pollutants before a woman reaches her mid-30s could treble her risk of developing breast cancer after the menopause, Canadian scientists said April. In a study in Occupational and Environmental Medicine, a British Medical Journal title, the researchers found that women exposed to synthetic fibers and petrol products during the course of their work appeared to be most at risk. More Childhood cancer patients enrolled in clinical trials need clearer communication about their role Bioscience Technology Online Share
A small study of children with cancer enrolled in therapeutic clinical research trials shows that they don't fully understand what physicians and parents tell them about their participation, nor do they feel they are genuinely involved in the choice to take part. While an estimated 70 percent of young cancer patients participate in clinical trials during their treatment, more than half of the 37 children who were interviewed for the study did not know or recall that their treatment was considered experimental or part of research, the investigators report.
