An exciting aspect of the study, published by Cell Press on December 2 in the American Journal of Human Genetics, is the association of tRNA mutations with elevated levels of prostate-specific antigen (PSA) in Austrian men diagnosed with various stages of prostate cancer. http://phys.org/news210520506.html Medicine & Health Thu, 02 Dec 2010 13:55:21 EST news210520506 It can be fatal if the clot breaks away and lodges in the lung (pulmonary embolism). The aim of this analysis of primary care data is to establish a clearer picture of the increased risk of venous thromboembolism in different cancers, and to help create bespoke guidelines for doctors in how to prevent the condition arising after a cancer diagnosis. http://phys.org/news208694365.html Medicine & Health Thu, 11 Nov 2010 11:10:02 EST news208694365 The future of cancer diagnosis may lie in just a few milliliters of blood, according to a research team led by Professor Arie Admon of the Technion-Israel Institute of Technology. http://phys.org/news207391308.html Medicine & Health Wed, 27 Oct 2010 09:42:04 EST news207391308 Researchers have identified a novel, dual-platform technology, the On-Q-ity Circulating Cancer Capture and Characterization Chip (C5), which they believe is more efficient than the commonly used single-platform device in identifying circulating tumor cells (CTCs) in breast cancer. http://phys.org/news204998120.html Medicine & Health Wed, 29 Sep 2010 21:00:01 EST news204998120 A test based on a panel of microRNAs under development by Rosetta Genomics, Ltd., in Rehovot, Israel, may allow for more precise diagnosis and better targeted therapy for patients with lung cancer. http://phys.org/news204997889.html Medicine & Health Wed, 29 Sep 2010 16:51:38 EST news204997889 (PhysOrg.com) -- What goes through a woman's mind when she first hears the words, "You have breast cancer"? One in eight women will hear those words at some point in their lives and yet very little research has been conducted about women's thoughts at this early stage before treatment or surgery. http://phys.org/news203267375.html Medicine & Health Thu, 09 Sep 2010 16:20:01 EST news203267375 Postmenopausal women diagnosed with colon cancer may be at increased risk of death if they fail to maintain a healthy body weight before cancer diagnosis, according to a study published in the September issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. http://phys.org/news203226833.html Medicine & Health Thu, 09 Sep 2010 05:10:13 EST news203226833 Integrating palliative care early in the treatment of patients with advanced lung cancer not only improved their mood and quality of life, it also extended their lives. In the August 19 New England Journal of Medicine, Massachusetts General Hospital (MGH) investigators report that patients with metastatic non-small-cell lung cancer (NSCLC) who received early palliative care along with standard treatment lived more than two months longer than patients receiving standard care only. Metastatic NSCLC is difficult to treat, and patients typically are expected to survive less than one year. http://phys.org/news201362074.html Medicine & Health Wed, 18 Aug 2010 17:00:01 EST news201362074 The boom in cancer biomarker investments over the past 25 years has not translated into major clinical success. The reasons for biomarker failures include problems with study design and interpretation, as well as statistical deficiencies, according to an article published online August 12 in The Journal of the National Cancer Institute. http://phys.org/news200848741.html Medicine & Health Thu, 12 Aug 2010 16:30:08 EST news200848741 In the first ever published estimate of the percentage and number of cancer survivors who live with their minor children, a team led by a Wake Forest University Baptist Medical Center researcher found that millions of cancer survivors are parenting young children, highlighting a group of survivors with very special needs. http://phys.org/news196944353.html Medicine & Health Mon, 28 Jun 2010 11:46:07 EST news196944353 (PhysOrg.com) -- To diagnose cancer reliably, doctors usually conduct a biopsy including tissue ana-lysis ? which is a time-consuming process. A microscopic image sensor, fitted in an endoscope, is being developed for in vivo cancer diagnosis, to speed up the detection of tumors. http://phys.org/news194849770.html Medicine & Health Fri, 04 Jun 2010 06:10:01 EST news194849770 A new study has found that when African American and white cancer patients are treated at similar, specialized cancer care institutions, mortality rates are roughly equal. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the findings suggest that where patients receive care may partly explain observed racial disparities in cancer mortality. http://phys.org/news188456700.html Medicine & Health Mon, 22 Mar 2010 06:50:25 EST news188456700 Researchers have developed a novel animal model showing that four commonly used chemotherapy drugs disrupt the birth of new brain cells, and that the condition could be partially reversed with the growth factor IGF-1. http://phys.org/news180269636.html Medicine & Health Thu, 17 Dec 2009 10:54:31 EST news180269636 Despite recent advances in diagnosis and treatment, the prognosis of patients with biliary tract cancer is still poor.

These findings could one day lead to a genetic test that could help select or predict successful treatment options for patients with this type of cancer. The results were published in the American Journal of Pathology. http://phys.org/news156619491.html Medicine & Health Wed, 18 Mar 2009 18:25:25 EST news156619491 Women diagnosed with breast cancer shoulder the emotional burden of disclosing their diagnosis to loved ones, managing the feelings of others at precisely the time when they need support themselves, according to research to be presented at the annual meeting of the American Sociological Association (ASA). http://phys.org/news137053304.html Medicine & Health Mon, 04 Aug 2008 07:21:44 EST news137053304
