Multidrug resistance (MDR) is the mechanism by which many cancers develop resistance to chemotherapy drugs, resulting in minimal cell death and the expansion of drug-resistant tumors. To address the problem of resistance, researchers at the National Institute of Biomedical Imaging and Bioengineering (NIBIB) at the National Institutes of Health (NIH) have developed nanoparticles that…
Many breast tumors grow in response to female hormones, especially estrogen. Drugs that reduce estrogen levels in the body often are effective in reducing tumor size and preventing recurrence of the cancer. But some tumors become resistant to these therapies and continue to grow and spread.
When a woman is diagnosed with the earliest stage of breast cancer, how aggressive should her treatment be? Will the non-invasive cancer become invasive? Or is it a slow-growing variety that will likely never be harmful? Researchers at the University of Michigan developed a new technology that can identify aggressive forms of ductal carcinoma in situ, or stage 0 breast cancer, from non-aggressive…
Preliminary tests have demonstrated that a new device may enable existing breast cancer imagers to provide up to six times better contrast of tumors in the breast, while maintaining the same or better image quality and halving the radiation dose to patients. The advance is made possible by a new device developed for 3D imaging of the breast by researchers at the Department of Energy's Thomas…
Pathologists have been largely diagnosing disease the same way for the past 100 years, by manually reviewing images under a microscope. But new work suggests that computers can help doctors improve accuracy and significantly change the way cancer and other diseases are diagnosed. A research team from Beth Israel Deaconess Medical Center (BIDMC) and Harvard Medical School (HMS) recently developed…
Researchers at Massachusetts Institute of Technology research center in Singapore have developed a new microfluidic device that tests the effects of electric fields on cancer cells. They observed that a range of low-intensity, middle-frequency electric fields effectively stopped breast and lung cancer cells from growing and spreading, while having no adverse effect on neighboring healthy cells.
An international team led by researchers at the Austrian Institute of Molecular Biotechnology (IMBA) in Vienna and the University of Maryland School of Medicine in Baltimore discovered that genetically determined breast cancer can be largely prevented by blocking a bone gene. An already approved drug could be quickly available and would then be the first breast cancer prevention drug.
Scientists from the University of Zurich have been able to understand for the first time why many cancer cells adapt relatively quickly to the treatment with therapeutic antibodies in invasive forms of breast cancer. Instead of dying off, they are merely rendered inactive. The researchers have now developed an active substance that kills the cancer cells very effectively without harming healthy…
Since the introduction of targeted therapies in oncology the task of the pathologist has expanded beyond histological diagnostics: today, the pathologist analyses tumour tissue samples to establish a molecular profile with tumour cell characteristics – which in turn become the targets of medication.
The ongoing debate about breast cancer diagnostics has left many women confused — particularly over what age they should get mammograms and who needs treatment. An issue with current methods is that they often identify lumps but cannot conclusively pinpoint which ones are cancerous. To help resolve this uncertainty, researchers have developed a pill that could improve imaging techniques so that…
A team of investigators from Houston Methodist Research Institute may have transformed the treatment of metastatic triple negative breast cancer by creating the first drug to successfully eliminate lung metastases in mice.
Johns Hopkins scientists report they have developed an antibody against a specific cellular gateway that suppresses lung tumor cell growth and breast cancer metastasis in transplanted tumor experiments in mice, according to a new study published in the February issue of Nature Communications.
Results from recent trials are promising: an almost 40% increased breast cancer detection rate from digital breast tomosynthesis (DBT) screening compared to conventional mammography.
A new EU-funded project HYPMED is developing a ground-breaking imaging method for more accurate detection of breast cancer and a better, more personalised, understanding of its response to therapy.
In a comprehensive modeling study, researchers from UC Davis and other institutions have found that breast cancer screening with digital mammography poses only a small risk of radiation-induced breast cancer for most women. However, the research showed increased risk for women with large breasts or breast implants, who must often receive extra screening views, increasing their radiation exposure.
Breast cancer screening has helped to detect cancer in its early stages, but it is unclear how important this contribution is to mortality reduction because treatment has greatly improved. Overdiagnosis and overtreatment remain associated risks that need to be fully assessed for screening to be of real benefit. Leading experts in this field passionately discussed these controversies in a…
Additional breast cancers found with MRI are sometimes larger and potentially more aggressive than those found on mammography, according to a study published online in the journal Radiology.
The mammography detection rate of an early-stage but potentially invasive type of breast cancer rises with age, according to a large new study from Germany published online in the journal Radiology.
A photograph may reveal how something looks, but direct observation can divulge how the objects behave. The difference can mean life or death, especially when it comes to fighting human disease. To help researchers examine exactly how human diseases work at the molecular level, Virginia Tech Carilion Research Institute scientist Deborah Kelly has developed a new set of tools to peer into the…
A magnetic resonance (MR) breast imaging technique that uses no ionizing radiation or contrast agent could reduce unnecessary biopsies by providing additional information about suspicious findings on X-ray screening mammography, according to a new study published online in the journal Radiology.
For some, TOR may bring to mind a Celtic mountain or perhaps an Internet privacy group. In the world of molecular biology it’s a cellular pathway that’s found in everything from yeast to mammals. mTOR (as it’s called in mammals) plays a central role in instructing the cell to grow and divide in response to nutrients. When it’s turned down, the cell shifts into a second, tidying mode,…
American Society of Human Genetics issues recommendations on age-appropriate genetic testing in children and adolescents.
Researchers at the University of California, San Diego School of Medicine and Moores Cancer Center have discovered a molecular mechanism that connects breast tissue stiffness to tumor metastasis and poor prognosis. The study may inspire new approaches to predicting patient outcomes and halting tumor metastasis.
Agendia co-founder and Chief Research Officer, Laura van't Veer, Ph.D., has won the European Inventor Award in the SME category. The European Inventor Award is a prestigious innovation award presented by the European Patent Office, with only 15 inventors nominated in a total of five categories worldwide.
“I am very concerned about the impact that Angelina Jolie has on the media,” Walter Rocca, professor of epidemiology and neurology at the Mayo Clinic in Rochester, Minnesota, stated. He wasn’t hinting to Jolie’s acting choices or waifish silhouette, but to the confusion surrounding her decision to remove her ovaries to prevent ovarian cancer. By Mélisande Rouger
