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.

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.

New study offers potential avenues for treatment of deadly nasopharyngeal cancer
A team of scientists from the Cancer Science Institute of Singapore at the National University of Singapore, National University Cancer Institute Singapore and National University Hospital Singapore, discovered a distinct mutational signature and nine significantly mutated genes associated with nasopharyngeal cancer, paving the way to developing novel therapies for this deadly 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.

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.

Delivering drugs on cue
Current drug-delivery systems used to administer chemotherapy to cancer patients typically release a constant dose of the drug over time -- but a new study challenges this 'slow and steady' approach and offers a novel way to locally deliver the drugs 'on demand,' as reported in the Proceedings of the National Academy of Sciences.

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.'

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.

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.

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.

Cancer by remote-control
One of the deadliest forms of paediatric brain tumour, Group 3 medulloblastoma, is linked to a variety of large-scale DNA rearrangements which all have the same overall effect on specific genes located on different chromosomes. The finding, by scientists at EMBL Heidelberg and collaborators, is published online today in Nature.

BPA exposure during fetal development raises risk of precancerous prostate lesions
A new study has found for the first time that the endocrine-disrupting chemical bisphenol A, BPA, reprograms the developing prostate, making the gland more susceptible to precancerous lesions and other diseases later in a man's life. The results will be reported Sunday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago.

Possible new weapon found for fighting some types of breast cancer
Researchers believe they have discovered one reason why some women with estrogen receptor-positive breast cancer may respond poorly or only temporarily to estrogen-blocking drugs such as tamoxifen. Results of a new study, which was presented Saturday at the joint meeting of the International Society of Endocrinology and the Endocrine Society: ICE/ENDO 2014 in Chicago, point to a previously unrecognized role of the androgen receptor.
