Study Reveals How Some Prostate Tumors Resist Treatment
March 19, 2013 11:45 am | News | CommentsHormonal therapies can help control advanced prostate cancer for a time. However, for most men, at some point their prostate cancer eventually stops responding to further hormonal treatment. This stage of the disease is called androgen-insensitive or castration-resistant prostate cancer.
New Cancer Diagnostic Technique Debuts
March 15, 2013 3:58 pm | News | CommentsCancer cells break down sugars and produce the metabolic acid lactate at a much higher rate than normal cells. This phenomenon provides a telltale sign that cancer is present. Now, a team of researchers has devised a molecular sensor that can detect levels of lactate in individual cells in real time.

Protein “Mousetrap” Stops Cancer-driving Enzyme
March 14, 2013 11:26 am | News | CommentsA seemingly obscure gene in the female fruit fly that is only active in cells that will become eggs has led researchers to the discovery of an atypical protein that lures, traps and inactivates the powerful Polo kinase, widely considered the master regulator of cell division.
The Importance of Genomics for Cancer Research
March 14, 2013 10:20 am | by Ruth Burton, PhD, Product Manager Genomic Solutions, Oxford Gene Technology | Articles | CommentsDespite significant advances, cancer remains one of the predominant causes of mortality in the modern world, and as such has remained a top research priority. It is a complex and continually evolving genetic disease and, as such, requires sophisticated tools for study.
Radiation for Breast Cancer Can Harm Hearts
March 13, 2013 5:24 pm | by MARILYNN MARCHIONE - AP Chief Medical Writer - Associated Press | News | CommentsWomen treated with radiation for breast cancer are more likely to develop heart problems later, even with the lower doses used today, troubling new research suggests. The risk comes from any amount of radiation, starts five years after treatment and lasts for decades, doctors found.
Imaging Drug Finds Cancerous Lymph Nodes
March 13, 2013 1:45 pm | by The Associated Press | News | CommentsThe Food and Drug Administration has approved a new imaging drug, Lymphoseek, from Navidea Biopharmaceuticals Inc., to help doctors locate lymph nodes in patients with breast cancer and skin cancer.
Bitter Melon Juice Kills Pancreatic Cancer Cells
March 13, 2013 9:31 am | News | CommentsA new study shows that bitter melon juice restricts the ability of pancreatic cancer cells to metabolize glucose, thus cutting the cells’ energy source and eventually killing them.
Biomarkers Help Screen for Malignant Kidney Cancer
March 11, 2013 11:20 am | News | CommentsA new immunoassay that tests for the presence of three biomarkers appears to be a valid screening method for the early detection of malignant kidney cancer, according to new data.
Cancer-Promoting Protein Doubles as Cell Suppressant
March 8, 2013 9:58 am | News | CommentsSome cellular proteins have multiple, and occasionally opposing, functions. Researchers demonstrated that the oncogenic protein SRSF1 can also trigger a stop in cell growth and prevent cancerous proliferation by stabilizing p53, the powerful tumor-suppressor protein.
Origin of Aggressive Ovarian Cancer Revealed
March 8, 2013 9:45 am | News | CommentsResearchers have discovered a likely origin of epithelial ovarian cancer (ovarian carcinoma), the fifth leading cause of cancer death among women in the United States.
Long-Used Osteoporosis Drug Carries Cancer Risk
March 5, 2013 4:44 pm | by MATTHEW PERRONE - AP Health Writer - Associated Press | News | CommentsA panel of federal health experts says a long-established bone strengthening drug should no longer be used by women because there is little evidence it works and it may actually increase the risk of cancer.
Obesity Gene Linked to Melanoma Risk
March 4, 2013 11:08 am | News | CommentsThe gene most strongly linked to obesity and overeating may also increase the risk of malignant melanoma– the most deadly skin cancer, new research reveals.
