(Press-News.org) ALEXANDRIA, Va. – New studies exploring breast cancer risk perceptions and use of radiotherapy and MRI for women with ductal carcinoma in situ (DCIS, a preinvasive form of breast cancer) were highlighted today in a virtual presscast in advance of the 2013 Breast Cancer Symposium. The Symposium will take place September 7-9, 2013, at the San Francisco Marriott Marquis in San Francisco.
Three major studies were highlighted in today's presscast:
Radiation therapy for DCIS is safe, and does not appear to increase the risk of developing or dying from cardiovascular disease: A population-based study conducted in the Netherlands found that cardiovascular disease incidence and mortality rates among DCIS survivors ten years after completion of radiation therapy were similar to those of the general population of Dutch women.
MRI around the time of surgery may be unnecessary for women with DCIS: A large, retrospective study of women who underwent a lumpectomy for DCIS found that adding an MRI scan to standard mammography immediately before or after surgery does not decrease locoregional recurrence rates.
A large survey suggests majority of women may have an inaccurate perception about their personal breast cancer risk: An analysis of survey data collected from nearly 10,000 Long Island, New York, women who were scheduled to undergo mammography screenings determined that roughly one in ten women had an accurate perception of her lifetime risk of developing breast cancer. Additionally, less than half of women said they had ever discussed breast cancer risk with their doctor.
"Oncologists are continuously reviewing their processes to ensure patients receive the best quality of care. Two studies presented today inform how we manage the growing number of patients with DCIS," said Steven O'Day, MD, American Society of Clinical Oncology Cancer Communications Committee member. "And another very important study points to the need for better communication between women and their doctors to ensure women receive appropriate breast cancer screening and, conversely, prevent unnecessary anxiety."
This year's Breast Cancer Symposium will bring together oncology professionals representative of the full spectrum of patient care to discover and discuss the latest research from more than 170 abstracts. Interactive discussions and presentations will focus on strengthening collaborative treatment approaches and enhancing patient care for the 234,580 newly diagnosed cases of breast cancer expected to occur in 2013*.
Six leading medical specialty societies co-sponsor the three-day, multidisciplinary symposium, including the American Society of Breast Disease, the American Society of Breast Surgeons, the American Society of Clinical Oncology, the American Society for Radiation Oncology, the National Consortium of Breast Centers and the Society of Surgical Oncology.

What scientists can see in your pee
2013-09-05
Researchers at the University of Alberta announced today that they have determined the chemical composition of human urine. The study, which took more than seven years and involved a team of nearly 20 researchers, has revealed that more than 3,000 chemicals or "metabolites" can be detected in urine. The results are expected to have significant implications for medical, nutritional, drug and environmental testing.
"Urine is an incredibly complex biofluid. We had no idea there could be so many different compounds going into our toilets," noted David Wishart, the senior ...
Children with behavioral problems more at risk of inflammation
2013-09-05
Children with behavioral problems may be at risk of many chronic diseases in adulthood including heart disease, obesity, diabetes, as well as inflammatory illnesses (conditions which are caused by cell damage).
Analyzing data on more than 4,000 participants in the Children of the 90s study at the University of Bristol, researchers from Harvard and Columbia's Mailman School of Public Health found that children with behavioral problems at the age of 8, had higher levels of two proteins (C-reactive protein—CRP; and Interleukin 6—IL-6) in their blood when tested at the age ...
China's clean-water program benefits people and the environment, Stanford research shows
2013-09-05
The brown, smog-filled skies that engulf Beijing have earned China a poor reputation for environmental stewardship. But despite China's dirty skies, a study led by Stanford environmental scientists has found that a government-run clean water program is providing substantial benefit to millions of people in the nation's capital.
The Miyun reservoir, 100 miles north of Beijing, is the main water source for the city's more than 20 million inhabitants. Greater agricultural demands and a decline in precipitation, among other factors, have cut the reservoir's output by two-thirds ...
Pest-eating birds mean money for coffee growers, Stanford biologists find
2013-09-05
In recent years, Stanford biologists have found that coffee growers in Costa Rica bolster bird biodiversity by leaving patches of their plantations as untouched rainforest.
The latest finding from these researchers suggests that the birds are returning the favor to farmers by eating an aggressive coffee bean pest, the borer beetle, thereby improving coffee bean yields by hundreds of dollars per hectare.
The study is the first to put a monetary value on the pest-control benefits rainforest can provide to agriculture, which the researchers hope can inform both farmers ...
Scientific reproducibility is hampered by a lack of specificity of the material resources
2013-09-05
A key requirement when performing scientific experiments is the accessibility of material resources, including the reagents or model organisms, needed to address a specific hypothesis. The published scientific literature is a source of this valuable information, but frequently lacks sufficient detail to the extent that researchers are unable to identify material resources used to perform experiments.
A study, published today in PeerJ, demonstrates the magnitude of the problem – a problem that negatively affects the ability of scientists to reproduce and extend reported ...
Clues in coral bleaching mystery
2013-09-05
Stanford, CA— Coral reefs are tremendously important for ocean biodiversity, as well as for the economic and aesthetic value they provide to their surrounding communities. Unfortunately they have been in great decline in recent years, much of it due to the effects of global climate change. One such effect, called bleaching, occurs when the symbiotic algae that are essential for providing nutrients to the coral either lose their identifying photosynthetic pigmentation and their ability to perform photosynthesis or disappear entirely from the coral's tissue. Without a healthy ...
Body's 'safety procedure' could explain autoimmune disease
2013-09-05
Monash University researchers have found an important safety mechanism in the immune system that may malfunction in people with autoimmune diseases, such as Multiple Sclerosis, potentially paving the way for innovative treatments.
Published today in Immunity, the research, led by Head of the Monash Department of Immunology Professor Fabienne Mackay, described for the first time how the body manages marginal zone (MZ) B cells, which form a general first line of attack against germs, but are potentially harmful.
MZ B cells are integral to our defenses as they rapidly ...
Space around others perceived just as our own
2013-09-05
A study from Karolinska Institutet in Sweden has shown that neurons in our brain 'mirror' the space near others, just as if this was the space near ourselves. The study, published in the scientific journal Current Biology, sheds new light on a question that has long preoccupied psychologists and neuroscientists regarding the way in which the brain represents other people and the events that happens to those people.
"We usually experience others as clearly separated from us, occupying a very different portion of space," says Claudio Brozzoli, lead author of the study at ...
Cheaper Chinese solar panels are not due to low-cost labor
2013-09-05
A study of the photovoltaic industries in the US and China shows that China's dominance in solar panel manufacturing is not driven solely by cheaper labour and government support, but by larger-scale manufacturing and resulting supply-chain benefits.
But the researchers say a balance could be achieved through future innovations in crystalline solar cell technology, which have the potential to equalise prices by enhancing access to materials and expanding manufacturing scale across all regions.
The study is published today in the Royal Society of Chemistry journal Energy ...
New computational approaches speed up the exploration of the universe
2013-09-05
How many different molecules can be created when you release one of the universe's most reactive substances, hydrogen cyanide, in the lab? And will the process create some particularly interesting molecules?
That is what scientists call a good question, because hydrogen cyanide seems to have played a role in creating some of life's building blocks. Hydrogen cyanide is an organic compound and it is found in large quantities in the universe. It may have helped in producing amino acids and DNA bases, some of life's basic molecules.
If hydrogen cyanide can lead to the formation ...
