Handheld scanner could make brain tumor removal more complete, reducing recurrence
Cancerous brain tumors are notorious for growing back despite surgical attempts to remove them -- and for leading to a dire prognosis for patients. But scientists are developing a new way to try to root out malignant cells during surgery so fewer or none get left behind to form new tumors. The method, reported in the journal ACS Nano, could someday vastly improve the outlook for patients.

Blood test for 'nicked' protein predicts prostate cancer treatment response
Prostate cancer patients whose tumors contain a shortened protein called AR-V7, which can be detected in the blood, are less likely to respond to two widely used drugs for metastatic prostate cancer, according to results of a study led by researchers at the Johns Hopkins Kimmel Cancer Center.

CNIO experts discover the genomic origin of telomere protectors
A study led by Centro Nacional de Investigaciones Oncologicas researchers has discovered that telomeric repeat-containing RNA do not originate in all telomeres that protect the 20 murine chromosomes, but do exclusively in chromosome 18 and, to a lesser extent, in chromosome 9. This peculiarity sets the stage for future genetic manipulation in mice with the aim of researching the in vivo role of these molecules in telomere biology and in illness. The results have been published in Nature Communications.

Genetic 'hotspot' linked to endometrial cancer aggressiveness
Scientists at The University of Texas MD Anderson Cancer Center in Houston have identified genetic mutations in endometrioid endometrial carcinoma, the most common form of this cancer of the uterine lining.

Breast cancer patients with bilateral mastectomy don't have better survival rates
Breast cancer patients treated with lumpectomy followed by radiation therapy survived as long as patients who had bilateral mastectomy, according to a large study conducted by researchers at the Stanford University School of Medicine and the Cancer Prevention Institute of California.

New method for non-invasive prostate cancer screening
A team of researchers led by Shaoxin Li at Guangdong Medical College in China has demonstrated the potential of a new, non-invasive method to screen for prostate cancer, a common type of cancer in men worldwide. They describe their laboratory success testing an existing spectroscopy technique called surface-enhanced Raman scattering with a new, sophisticated analysis technique called support vector machine.

Increase seen in use of double mastectomy
Among women diagnosed with early-stage breast cancer in California, the percentage undergoing a double mastectomy increased substantially between 1998 and 2011, although this procedure was not associated with a lower risk of death than breast-conserving surgery plus radiation, according to a study in the Sept. 3 issue of JAMA. The authors did find that surgery for the removal of one breast was associated with a higher risk of death than the other options examined in the study.

Enzyme controlling metastasis of breast cancer identified
Researchers at the University of California, San Diego School of Medicine have identified an enzyme that controls the spread of breast cancer. The findings, reported in the current issue of PNAS, offer hope for the leading cause of breast cancer mortality worldwide. An estimated 40,000 women in America will die of breast cancer in 2014, according to the American Cancer Society.

'Prepped' by tumor cells, lymphatic cells encourage breast cancer cells to spread
Breast cancer cells can lay the groundwork for their own spread throughout the body by coaxing cells within lymphatic vessels to send out tumor-welcoming signals, according to a new report by Johns Hopkins scientists.

Sabotage as therapy: Aiming lupus antibodies at vulnerable cancer cells
Yale Cancer Center researchers may have discovered a new way of harnessing lupus antibodies to sabotage cancer cells made vulnerable by deficient DNA repair. The study, led by James E. Hansen, M.D., assistant professor of therapeutic radiology at Yale School of Medicine, found that cancer cells with deficient DNA repair mechanisms (or the inability to repair their own genetic damage) were significantly more vulnerable to attack by lupus antibodies.

Global snapshot of infectious canine cancer shows how to control the disease
While countries with dog control policies have curbed an infectious and gruesome canine cancer, the disease is continuing to lurk in the majority of dog populations around the world, particularly in areas with many free-roaming dogs. This is according to research published in the open-access journal BMC Veterinary Research.
