Alcohol use, tobacco use and male gender associated with an earlier onset of colorectal cancer

Colorectal cancer is the second leading cause of cancer deaths, according to background information in the article. Screening asymptomatic patients is an important strategy for reducing these deaths, because by the time patients experience symptoms, the cancer may have progressed beyond the point where it can be cured.

Colorimetric screening detects DNA, small molecules and proteins

Using the unusual color properties of gold at the nanoscale, scientists at Northwestern University have developed a "litmus test" for DNA and small molecule binding that eventually could be used by pharmaceutical companies to rapidly identify promising candidates for new anti-cancer drugs.

Guidelines for medication withdrawal

Although thousands of scientific papers evaluate and compare new and established drugs each year, providing evidence to help doctors prescribe safe and effective doses, almost no studies focus on when or how to stop these medications, even late in life.

Biodegradable drug containing nano-particles effective in killing human breast tumors

Research studies, based at the University of Pennsylvania, demonstrate that biodegradable nano-particles containing two potent cancer-fighting drugs are effective in killing human breast tumors.

Lack of response to herceptin may be reversed with PI3K inhibiting agents

Breast cancer patients with HER2-positive tumors who don't respond to Herceptin (trastuzumab) may benefit from cocktail therapy that includes Herceptin along with one or more PI3K inhibiting agents, say researchers at the University of Texas M. D. Anderson Cancer Center.

Exposure to arsenic in utero and early childhood tied to lung disease and cancer in adults

Children who are exposed to high levels of arsenic in their drinking water are seven to 12 times more likely to die of lung cancer and other lung diseases in young adulthood, a new study by University of California, Berkeley, and Chilean researchers suggests.

Removal of a woman's ovaries raises risk of dementia

Mayo Clinic researchers have found that ovariectomy, surgical removal of a woman's ovaries, raises her risk of developing dementia or cognitive impairment. Risk is especially increased if a woman has her ovaries removed at a young age.

Salivary biomarkers of existing periodontal disease

A University of Kentucky study published in the Journal of American Dental Association could help change the diagnosis and treatment of periodontal disease.

New discovery could help improve some forms of chemotherapy

The research looked at XPB helicase from an archaea, a single cell organism similar to bacteria. Helicases are enzymes that unwind or separate the strands of the nucleic acid double helix, an action that is critical to transcription and nucleotide excision repair (NER), as well as other cell processes.

Fullerene shows promise in reducing radiation side effects

Using transparent zebrafish embryos, researchers at Jefferson Medical College in Philadelphia have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation.

Access to breast cancer wonder drug will depend on where you live

Access to a potentially life-saving breast cancer drug in the UK has nothing to do with need but rather where they happen to live.

Discovery of virus implicated in genetics of prostate cancer

The Open Access journal PLoS Pathogens has published an article detailing research that identifies a new retrovirus in the tissue of human prostate tumors.

Assessment of health-related quality of life in children with cancer: consistency and agreement between parent and child reports

Researchers and physicians can confidently assess quality of life factors in pediatric patients from either the child or parents, according to a new study.

New approach to treating hepatitis C virus

Last year Peter Sarnow, PhD, professor of microbiology and immunology at the Stanford University School of Medicine, identified a previously unknown mechanism that the hepatitis C virus uses to replicate, yielding a promising new approach to combating the disease-causing virus.

Protein loss linked to colon polyp risk from growth hormone

The use of growth hormone therapy has been linked in some people to the development of colon polyps, a possible precursor to colorectal cancer - but medical researchers have debated the extent of a cancer risk.

Risk of invasive breast carcinoma among women diagnosed with ductal carcinoma in situ and lobular carcinoma in situ

A new study of women with early stage, localized breast cancer identifies new patterns and risk factors for invasive disease that may influence how patients are treated.

Discovery of new human retrovirus

Howard Hughes Medical Institute researchers and their colleagues have discovered a new retrovirus in humans that is closely related to a cancer-causing virus found in mice. Their findings describe the first documented cases of human infection with a retrovirus that is native to rodents.
