Breast Cancer - Adjuvant Tamoxifen Improves 15-Year Survival By One Third
7/29/2011
For women with breast cancer who take adjuvant Tamoxifen daily for 5 years, their risk of dying from the disease drops by one third, compared to their chances without the drug, researchers reported in The Lancet today. They referred specifically to women with estrogen-receptor positive breast cancer, also known as hormone-sensitive breast cancer...
Using a "systems biology" approach - which focuses on understanding the complex relationships between biological systems - to look under the hood of an aggressive form of breast cancer, researchers for the first time have identified a set of proteins in the blood that change in abundance long before the cancer is clinically detectable. The findings, by co-authors Christopher Kemp, Ph.D...
The eon-spanning clock of evolution - the millions of years that generally pass before organisms acquire new traits - belies a constant ferment in the chambers and channels of cells, as changes in genes and proteins have subtle ripple effects throughout an organism...
The Future Of 3-D Is Breast Cancer Detection; Saves Time, Money
7/29/2011
A Seattle, Washington based hospital has announced the launch of a new 3-D mammography imaging technology, or better known as tomosynthesis now, is available for patient appointments. This development will make it possible for more precise readings that reduce the need for follow-up appointments by up to 40% saving all parties serious cash...
Male Circumcision Lowers Prevalence Of Penile Precancerous Lesions Among African Men
7/29/2011
A University of North Carolina-led international study shows that among Kenyan men, circumcision is associated with a lower prevalence of human papillomavirus-associated precancerous lesions of the penis. Human papillomavirus HPV is a sexually transmitted virus that plays an important role in genital cancers in men and women, including cancers of the penis and cervix...
Patient Marries 3 Days Before Cancer Surgery To Remove 10-Inch Tumor
7/29/2011
No cancer surgery is easy, but the two operations David Bieszke underwent at Loyola University Hospital to remove an aggressive, 10-inch tumor were especially challenging. The tumor extended from his navel to his diaphragm. It choked a major blood vessel, and invaded smaller blood vessels to both kidneys. It would take two surgeries, each lasting six hours, to remove the tumor...
Convergence In Head And Neck Cancer --Centers Collaborate To Reveal Unexpected Genetic Mutations
7/29/2011
Baltimore, MD; Boston and Cambridge MA; Pittsburgh, PA; and Houston, TX . Thurs. July 28, 2011 -- Powerful new technologies that zoom in on the connections between human genes and diseases have illuminated the landscape of cancer, singling out changes in tumor DNA that drive the development of certain types of malignancies such as melanoma or ovarian cancer...
The National Cancer Institute has awarded $8.2 million over the next five years to Fred Hutchinson Cancer Research Center to extend its role as the coordinating hub of a nationwide research consortium that aims to better understand the link between obesity and cancer...
New Protein Structure Model To Inhibit Cancer
7/29/2011
Researchers at the University of Hertfordshire have developed a new structural model of a protein, which makes it possible to develop more effective drugs to target diseases such as cancer, heart disease and influenza...
Human blood is a precious resource. Because stored blood has a very limited shelf life, keeping every available unit of it suitable for medical use is a crucial function at hospitals and other health care facilities especially during supply shortages such as those currently being experienced in the Triad, other parts of North Carolina and numerous sections of the country...
