New Study Begins for Kids with High Risk Cancer, Neuroblastoma
Molecular Insight Pharmaceuticals has announced the initiation of a clinical trial of Azedra in pediatric neuroblastoma patients. Neuroblastoma is a type of neuroendocrine cancer that primarily affects children and is the most common solid tumor in children outside of the brain. More »
Usage of Testicular Cancer Markers Too Limited, Say Researchers
A standard part of testicular cancer care isn't used in more than half of all patients who have the condition, researchers have found.
Doctors generally rely on a series of three serum-based tumor markers for testicular cancer, since these are helpful with diagnosis, prognostication and surveillance for disease recurrence following treatment. More »
Researchers Find that a Small Molecule Can Block Cancer Cell Division
By activating a cancer suppressor gene, a small molecule called nutlin-3a can block cancer cell division, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health.
This activation of the p53 gene leads to cellular senescence, a process by which cells lose their ability to grow and divide. An opportunity for new genetic mutations occurs each time a cell divides, so limiting the number of cell divisions in a cancer cell inhibits tumor progression. More »
Protecting Yourself from the Sun to Avoid Skin Cancer
Before leaving home for a day of outdoor activity, take appropriate precautions to ensure that your and your family's skin is well-protected, as the majority of all skin cancers are caused by the sun. More »
Obese Women Experience More Aggresive Breast Cancer
Obese women with breast cancer have lower rates of survival, and suffer a more intense form of the disease, according to recently-published research.
"The more obese a patient is, the more aggressive the disease," said Massimo Cristofanilli, MD, associate professor of medicine in the Department of Breast Medical Oncology at The University of Texas M.D. Anderson Cancer Center. "We are learning that the fat tissue may increase inflammation that leads to more aggressive disease." More »
Genistein in Soybeans May Halt Prostate Cancer Spread
Genistein, an antioxidant found in soybeans, almost completely prevented the spread of human prostate cancer in mice, according to a study published in the journal Cancer Research. In the study, genistein was used in an amount equivalent to what a human being would consume in a soybean-rich diet. More »
Genetic Markers Identify Probability of Lung Cancers Recurrence
Genetic alterations in tumors and tissue taken from early-stage lung cancer patients are clear pointers to which cancers might recur. Researchers say the findings could change the approach to treating even the smallest lung cancers—the size of a pea—which are known to recur within five years in 30 to 40 percent of patients. More »
Researchers Find that Head and Neck Cancers May Be Different Diseases
Different risk factors for head and neck cancer have been identified by researchers at Johns Hopkins Kimmel Cancer Center, raising the possibility that they are different forms of these diseases. More »
Increased Risk of Breast Cancer Recurrence Tied To High Levels of Estrogen
Women whose breast cancer returned after treatment had almost twice as much estrogen in their blood than did women who remained cancer-free, according to a newly published study.
The study's lead author, Cheryl L. Rock, Ph.D., a professor in the Department of Family and Preventive Medicine at the University of California, San Diego, said that high levels of estrogen—which lead to the initial development of breast cancer—could be associated with an increased risk of recurring cancer.

Stress May Increase HPV and Cervical Cancer Risk
Sress can reduce the immune system's ability to resist HPV, a common sexually transmitted disease that may lead to cancer, according to a recent study published in the Annals of Behavioral Medicine. No such association is seen, however, between past major life events, such as divorce or job loss, and the body's response to the infection. More »
