That is the conclusion of a new study published in the April 1, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study's findings could help physicians and other clinicians as they discuss test results with women who undergo BRCA gene testing. http://www.physorg.com/news155810166.html Medicine & Health Mon, 09 Mar 2009 09:36:59 EST news155810166 By targeting and disabling a protein frequently found in melanoma tumors, doctors may be able to make the cancer more vulnerable to chemotherapy, according to early results of a clinical study conducted by researchers in the Duke Comprehensive Cancer Center. http://www.physorg.com/news155559442.html Medicine & Health Fri, 06 Mar 2009 10:58:10 EST news155559442 Breast cancer patients 35 years old and younger have higher rates of their cancer returning after treatment than older women patients with the same stage of cancer, and their risk of recurrence is greatly impacted by the type of treatment they received, according to a March 1 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO). http://www.physorg.com/news155397867.html Medicine & Health Wed, 04 Mar 2009 14:04:56 EST news155397867 In one of the first studies to examine maternal and newborn health risks and colorectal cancer, UC Davis researchers have found that women diagnosed with the disease during or shortly after their pregnancies have the same survival as women who have the disease and are not pregnant.

This segment of the population is growing faster than any other age group and not surprisingly, the incidence of glioblastoma in older adults is on the rise. Because survival in older patients tends to be short and they have a higher risk of suffering debilitating side effects from therapy, physicians are unsure how to manage their treatment. A new study examining the patterns of treatment in older patients with glioblastoma was published in Annals of Neurology, the official journal of the American Neurological Association. http://www.physorg.com/news151076329.html Medicine & Health Tue, 13 Jan 2009 13:38:49 EST news151076329 A new study sheds light on a little understood biological process called quiescence, which enables blood-forming stem cells to exist in a dormant or inactive state in which they are not growing or dividing. According to the study's findings, researchers identified the genetic pathway used to maintain a cell's quiescence, a state that allows bone marrow cells to escape the lethal effects of standard cancer treatments. http://www.physorg.com/news150726406.html Biology Fri, 09 Jan 2009 12:26:46 EST news150726406 UC Davis Cancer Center researchers report today the discovery of a molecule that targets glioblastoma, a highly deadly form of cancer.
