Nanoparticles, 'PH Phoresis' Could Improve Cancer Drug Delivery
7/11/2013
Researchers have developed a concept to potentially improve delivery of drugs for cancer treatment using nanoparticles that concentrate and expand in the presence of higher acidity found in tumor cells...
Molecular Subtyping Of Breast Cancer Shows Potential Of Personalized Medicine
7/11/2013
A new study at the University of Miami's Sylvester Comprehensive Cancer Center shows the potential of personalized medicine to guide therapy in early-stage, invasive breast cancer. The study in the rapidly advancing field of molecular subtyping was led by Stefan Gluck, M.D., Ph.D., professor of medicine...
Fish Oils Increase Risk Of Prostate Cancer
7/11/2013
Men who eat a lot of oily fish or consume omega supplements should watch out, new research reveals that males with high blood concentrations of omega-3 fatty acids are at a higher risk of developing prostate cancer. The finding comes from a large prospective study published in the Journal of the National Cancer Institute...
New evidence suggests that using advanced genetics technologies to monitor for remaining cancer cells after treatment may soon become an effective tool to inform treatment decisions and ultimately predict patient outcomes for patients with a particularly aggressive form of acute lymphocytic leukemia (ALL)...
Too Frequent Cervical-Cancer Screenings May Cause More Harm Than Good
7/11/2013
For decades, women between the ages of 21 and 69 were advised to get annual screening exams for cervical cancer. In 2009, however, accumulating scientific evidence led major guideline groups to agree on a new recommendation that women be screened less frequently: every three years rather than annually...
Alzheimer's May Protect From Cancer And Vice Versa
7/11/2013
Patients with Alzheimer's disease have a lower risk of developing cancer, while seniors with cancer have lower rates of Alzheimer's disease compared to cancer-free people of the same age, researchers from the National Research Council of Italy, Milan, reported in the journal Neurology. Study author, Dr...
Common Cause For Brain Tumors In Children
7/11/2013
Brain cancer is the primary cause of cancer mortality in children. Even in cases when the cancer is cured, young patients suffer from the stress of a treatment that can be harmful to the developing brain. In a search for new target structures that would create more gentle treatments, cancer researchers are systematically analyzing all alterations in the genetic material of these tumors...
Potential Biomarker To Identify Disrupted Micronuclei In Solid Tumors
7/11/2013
Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis...
Secrets Of Tumor-Suppressor PTEN Revealed
7/11/2013
Genetic mutations aren't the only thing that can keep a protein called PTEN from doing its tumor-suppressing job. Johns Hopkins researchers have now discovered that four small chemical tags attached (reversibly) to the protein's tail can have the same effect, and they say their finding may offer a novel path for drug design to keep PTEN working...
Breast Cancer An Increased Risk For Women Who Give Birth To Multiple Babies After IVF
7/11/2013
Women who give birth to multiple babies following IVF treatment are at a higher risk of breast cancer than those giving birth to singletons or who remain childless. Dutch investigators from the Omega study group said the explanation may not be the multiple pregnancy per se but a maternal trait related to a higher implantation potential and to breast cancer itself...
