Stress from social isolation, combined with a high-fat diet, increases levels of a brain neurotransmitter - neuropeptide Y, or NPY - in mice that then promotes obesity, insulin resistance, and breast cancer risk, say researchers at Georgetown Lombardi Comprehensive Cancer Center, a part of Georgetown University Medical Center (GUMC). Major increases in NPY levels are seen when isolation and the high fat diet are combined...

Breast cancer stem cells wear a cell surface protein that is part nametag and part bull's eye, identifying them as potent tumor-generating cells and flagging their vulnerability to a drug, researchers at The University of Texas MD Anderson Cancer Center report online in Journal of Clinical Investigation. "We've discovered the ...

Apigenin, a natural substance found in grocery store produce aisles, shows promise as a non-toxic treatment for an aggressive form of human breast cancer, following a new study at the University of Missouri. MU researchers found apigenin shrank a type of breast cancer tumor that is stimulated by progestin, a ...

A large, multicenter study found that the Breast Imaging and Reporting Data Systems (BI-RADS) terminology used by radiologists to classify breast imaging results is useful in predicting malignancy in breast lesions detected with MRI. Results of the study are published online in the journal Radiology. "BI-RADS was developed to standardize ...

Radiotherapists are constantly battling in order to administer the correct dose of radiotherapy, as respiratory movement during radiotherapy poses a certain risk that a tumor receives either a dose that is insufficient, or the surrounding healthy tissue is being subjected to a potentially toxic over-dose. Dr. Amira Ziouèche presented a ...

The fact that treating cancer patients with multiple drugs often results in better outcomes than a single drug treatment is long been known amongst the medical profession. However, a MIT study published in the May 11 issue of Cell has just demonstrated that the order and timing of administering drugs ...

Using a concentrated, highly targeted dose of radiation to the breast has equally good results as irradiating the whole area, with no adverse effects on survival and a much better cosmetic outcome, Hungarian researchers have found...

Respiratory movement during radiotherapy makes it difficult to hit the right treatment target and this in turn can lead to an under-dose of radiation to the tumour, or a potentially toxic over-dose to the surrounding healthy tissue. Getting this right is a real challenge for the radiotherapist, but new techniques ...
