Estrogen receptor β limits breast cancer growth and indicates outcome
In a June 24th study in the Journal of Clinical Investigation, Rong Li and colleagues at the University of Texas determined that activation of the estrogen receptor β (ERβ) limits tumor cell growth.

3D mammography detects more invasive cancers and reduces call-back rates
Reporting in the June 25 issue of JAMA, researchers from Penn Medicine and other institutions found that 3D mammography -- known as digital breast tomosynthesis -- found significantly more invasive, or potentially lethal, cancers than a traditional mammogram alone and reduced call-backs for additional imaging.

Combo tumor imaging can distinguish malignant & benign breast tumors, help avoid biopsies
Imaging breast tumors using four approaches together can better distinguish malignant breast tumors from those that are benign, compared with imaging using fewer approaches, and this may help avoid repeat breast biopsies, according to a study published in Clinical Cancer Research, a journal of the American Association for Cancer Research.

Cell division discovery could optimise timing of chemotherapy and explain some cancers
Research led by the University of Warwick in collaboration with groups in Nice and Rotterdam has been able to demonstrate how the cycle of cell division in mammalian cells synchronizes with the body's own daily rhythm, its circadian clock. The study not only helps to explain why people with sustained disrupted circadian rhythms can be more susceptible to cancer, it may also help establish the optimal time of day to administer chemotherapy.

3D Mammography finds more invasive cancers and reduces unnecessary recalls
3D Mammography finds significantly more invasive cancers and reduces unnecessary recalls, according to a large, retrospective study published in June 25 issue of the Journal of the American Medical Association. The study features data from University Hospitals Case Medical Center Seidman Cancer Center. The study, the largest of its kind, focused on the impact of 3D mammography at a diverse range of sites across the US, looking at nearly half a million mammograms at 13 sites.

Addition of 3-D imaging technique to mammography increases breast cancer detection rate
The addition of tomosynthesis, a 3-dimensional breast imaging technique, to digital mammography in more than 170,000 examinations was associated with a decrease in the proportion of patients called back for additional imaging and an increase in the cancer detection rate, according to a study in the June 25 issue of JAMA.

Cancer: The roots of evil go deep in time
Every year around 450,000 people in Germany are diagnosed with cancer. Each one of them dreams of a victory in the battle against it. But can cancer ever be completely defeated? Researchers at Kiel University have now reached a sobering conclusion.

To advance care for patients with brain metastases: Reject five myths
Professional pessimism and out-of-date 'myths,' rather than current science, are guiding and compromising the care of patients with cancer that has spread to the brain, says a blue-ribbon panel of experts from leading academic centers in an article published online June 24 in Neurosurgery. The authors identify five key misconceptions that must be addressed -- and how to address them -- in order to advance new thinking in the treatment of brain cancer.

New possibilities for leukemia therapy with a novel mode of leukemia cell recognition
Scientists at A*STAR's Singapore Immunology Network have discovered a new class of lipids in the leukemia cells that are detected by a unique group of immune cells. By recognizing the lipids, the immune cells stimulate an immune response to destroy the leukemia cells and suppress their growth. The newly identified mode of cancer cell recognition by the immune system opens up new possibilities for leukemia immunotherapy.

Cancer genes hijack enhancers
Unlike most other forms of cancer, medulloblastomas exhibits very few mutations in growth-promoting genes. In collaboration with an international team of colleagues, scientists from the German Cancer Research Center have now made an important discovery about a particularly malignant subgroup of medulloblastomas: often the cancer-causing genes are transcribed at higher or lower levels than normal. This change is due to regulatory mechanisms that were previously unknown. For example, one cancer-gene hijacks a so-called 'enhancer.'

Study sheds light on racial disparity in colon cancer
African-Americans with colon cancer are half as likely as Caucasian patients to have a type of colon cancer that is linked to better outcomes. The finding may provide insight into why African-Americans are more likely to die of colon cancer than Caucasians with the same stage of disease.

The colon has a safety mechanism that restricts tumor formation
Colon cancer development starts with the formation of benign tumors called adenomas. It is estimated that between 30 and 50 percent of people over 50 will develop one of these tumors. These adenomas or polyps are pre-cancerous lesions that over many years, can progress to colon cancer. Scientists at the IRB Barcelona have discovered that the colon has a safety mechanism to restrict the formation and growth of adenomas. The study was published on Sunday in Nature Cell Biology.

Cancer chain in the membrane
Supercomputer simulations reveal clusters of a protein linked to cancer warp cell membranes -- findings could help design new anticancer drugs. Researchers at the UTHealth Medical School used XSEDE/TACC supercomputers Lonestar and Stampede to simulate molecular dynamics of Ras protein clusters at the cell membrane. Simulations give greater understanding of Ras protein role in cancer and provide models for further experimental tests.

Scientists use X-rays to look at how DNA protects itself from UV light
The molecular building blocks that make up DNA absorb ultraviolet light so strongly that sunlight should deactivate them -- yet it does not. Now scientists have made detailed observations of a 'relaxation response' that protects these molecules, and the genetic information they encode, from UV damage.

Long non-coding RNAs can encode proteins after all
Case Western Reserve School of Medicine scientists have made an extraordinary double discovery. First, they have identified thousands of novel long non-coding ribonucleic acid transcripts. Second, they have learned that some of them defy conventional wisdom regarding lncRNA transcripts, because they actually do direct the synthesis of proteins in cells. Both of the breakthroughs are detailed in the June 12 issue of Cell Reports.

Is focal treatment for prostate cancer as effective in the long-term as radical therapies?
Focal therapy for prostate cancer, in which only the tumor tissue is treated with cryoablation (freezing), can prolong life, result in less complications such as incontinence, and improve post-treatment quality of life. But the long-term effectiveness of focal treatments has not been well-studied. A new analysis that followed patients treated with optimized cryoablation of prostate cancer for an average of 10 years post-treatment is published in Journal of Men's Health.

Young indoor tanning increases early risk of skin cancer
Dartmouth researchers have found that early exposure to the ultraviolet radiation lamps used for indoor tanning is related to an increased risk of developing basal cell carcinomas at a young age. Their findings are reported in the July 2014 issue of Pediatrics. Since indoor tanning has become increasingly popular among adolescents and young adults, this research calls attention to the importance of counseling young people about the risk of indoor tanning.
