Injectable Contraceptives May Increase Breast Cancer Risk In Younger Women
4/10/2012
The first large-scale U.S.-based study to evaluate the link between an injectable form of progestin-only birth control and breast cancer risk in young women has found that recent use of a year or more doubles the risk. The results of the study, led by breast cancer epidemiologist Christopher I. Li, M.D., Ph.D...
Stem Cell Arsenic Exposure Raises Cancer Risk
4/09/2012
A study published online in Environmental Health Perspectives reports that researchers from the National Institutes of Health have discovered how normal stem cells can turn into cancer stem cells and spur tumor growth through exposure to arsenic. Evidence of earlier studies shows that the drinking water of millions of people worldwide is affected by inorganic arsenic, which is a human carcinogen...

Vaccine Yielded Encouraging Long-Term Survival Rates In Certain Patients With NSCLC
4/09/2012
Long-term follow-up of a phase II clinical trial showed encouraging survival in some patients with stage 3B/4 non-small cell lung cancer treated with belagenpumatucel-L, a therapeutic vaccine. The findings were presented at the AACR Annual Meeting 2012. "This is a novel immunotherapy that appears to show unusually long survival in some patients," said Lyudmila Bazhenova, M.D...
A Viable Way For Colorectal Cancer Patients To Overcome Drug Resistance
4/09/2012
When combined with other treatments, the drug cetuximab - which works by slowing or stopping the growth of cancer cells - has been shown to extend survival in certain types of cancer, including metastatic colorectal cancers. Unfortunately, about 40 percent of colorectal cancer patients - specifically those who carry a mutated form of a gene called KRAS - do not respond to the drug...

Stem Cells Turned Cancerous By Arsenic, Spurring Tumor Growth
4/09/2012
Researchers at the National Institutes of Health have discovered how exposure to arsenic can turn normal stem cells into cancer stem cells and spur tumor growth. Inorganic arsenic, which affects the drinking water of millions of people worldwide, has been previously shown to be a human carcinogen. A growing body of evidence suggests that cancer is a stem-cell based disease...
Racial Differences In Breast Cancer Risk Influenced By Vitamin D
4/09/2012
American women of African ancestry are more likely than European Americans to have estrogen receptor (ER) negative breast cancer. There continues to be discussion about the role of low levels of vitamin D in the development of breast cancer for these women...
