Bone Fluoride Levels Not Associated With Osteosarcoma

image A study that investigated bone fluoride levels in individuals with osteosarcoma, which is a rare, primary malignant bone tumor that is more prevalent in males has been released by the International and American Associations for Dental Research have released in its iJournal of Dental Research/i. Since there has been controversy as to whether there is an association between fluoride and risk for osteosarcoma, the purpose of this study, titled "An Assessment of Bone Fluoride and Ost...

Familial Breast Cancer Patients Have Characteristic Progressive Telomere Shortening

image It has emerged that telomeres, the complex structures that protect the end of chromosomes, of peripheral blood cells are significantly shorter in patients with familial breast cancer than in the general population. Results of the study carried out by the Human Genetics Group of the Spanish National Cancer Research Centre (CNIO), led by Javier Benitez, to be published in open-access journal iPLoS Genetics/i on July 28th, reflect that familial, but not sporadic, breast cancer cases...

Study Reveals How Maspin Protein Reduces Growth and Spread of Cancer Cells

image A new way to control cancer development has been developed by scientists; thus providing a new hope for survival to scores of people infected by the disease. Lawson Health Research Institute's Dr. John Lewis, Dr. Ann Chambers, and colleagues discovered that maspin, a cellular protein, could reduce the growth and spread of cancer cells, but only when it is in the nucleus. To assess the effects of maspin on tumour growth and development, the team tested two aggressive cance...

Role of Mammogram Screening in Breast Cancer Deaths

image In Europe, mammogram screening have little impact on reducing breast cancer death rates, finds study. Three pairs of countries with similar access to treatment but varying levels of breast screening showed scant difference in the degree of mortality attributed to the disease, researchers reported. The study, published online by the British Medical Journal, adds to a growing body of evidence suggesting that two decades of routine screening has yielded modest results at b...

Study Sheds Light on How Some Breast Cancers Alter Their Sensitivity to Estrogen

image Study conducted by researchers from John Hopkins University has shed light on why some breast cancer cells become resistant to the anti-cancer effects of the drug tamoxifen. The key is a discovery of two genetic "dimmer switches" that apparently control how a breast cancer gene responds to the female hormone estrogen. In a report published online July 7 by IHuman Molecular Genetics/I, the scientists show how a gene known as RET in breast cancer cells responds to estrogen by dia...

Tiny Drug Transporter to Fight Cancer Cells Developed

image Scientists from Ohio State University have developed a nano-sized drug transporter that has the ability to silence damaging genes by finding the equivalent of an expressway into a target cell. This transporter may help improve cancer treatments. The transporter, called a nanocarrier, is a lipid-based structure containing a piece of RNA. Lipids are fatty molecules that help maintain the structure of cell membranes. The RNA segment encased in the carrier sets off a pro...

Space Study Could Reveal Superior Therapies for Cancer

image US astronomers, including one of Indian-origin, have said that the information gathered from studying the universe is showing promise in yielding new cancer treatments. Studying how chemical elements emit and absorb radiation inside stars and around black holes, Ohio State University astronomers Sultana Nahar and Anil Pradhan are working with medical physicists and radiation oncologists to develop a potential new radiation treatment-one that is intended to be tougher on tumors, but g...

Breast Cancer Risk Tied to Breast Density

image Women with breasts that appear dense on mammograms are at a higher risk of breast cancer than women with less dense breasts, and the tumors in dense breasts are more likely to have certain aggressive characteristics, according to a study published online July 27 in thei Journal of the National Cancer Institute./i Mammographic breast density--a reflection of the proportions of fat, connective tissue, and epithelial tissue in the breast--is a well-established risk factor for breast...

Livestock Farms Linked to Increased Blood Cancer Risk

image Growing up on a livestock farm seems to raise the risk of developing blood cancers, shows research published in Occupational and Environmental Medicine. The risk of developing a blood cancer was three times as high for those who had grown up on a poultry farm, the study shows. Previous research has suggested that farmers are at increased risk of blood cancers, the possible explanations for which have focused on exposure to pesticides or infections as a result of conta...

Cancer and 9/11 Exposure Not Related: US Review

image There is no proof that exposure to the dust and rubble from the World Trade Center after the attacks of September 11, 2001 caused cancer, a US government review of scientific studies has shown. The review of peer-reviewed medical and scientific literature sparked anger among some firefighters, police and other first responders who said they have seen too many colleagues suffer from cancer to believe that there was no link. "Insufficient evidence exists at this time to pro...
