New discoveries about Tumor-Suppressing Protein could help reduce treatment side effects

Researchers at the Stanford University School of Medicine have untangled two distinct ways in which a common, naturally occurring "tumor-suppressor" protein works. The separation of these two functions -- which can have quite different consequences -- could enhance efforts to develop treatment approaches that mitigate the sometimes-devastating side effects of radiotherapy and chemotherapy.

The protein, p53, is mutated or missing in more than half of all human cancers, and most cancers involve at least some compromise in its function.

Blood test for lung cancer? Characteristic patterns in microRNA reveal disease

Researchers have identified characteristic patterns of molecules called microRNA (miRNA) in the blood of people with lung cancer that might reveal both the presence and aggressiveness of the disease, and perhaps who is at risk of developing it. These patterns may be detectable up to two years before the tumor is found by computed tomography (CT) scans.

The findings could lead to a blood test for lung cancer, according to a researcher with the Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute who helped lead study.

Coffee provides protections from a type of breast cancer: Study

Recent research from Sweden has shown that drinking coffee may help curb the risk of developing a certain type of breast cancer. For the study they compared coffee consumption in postmenopausal women with breast cancer and women of the same age without cancer, they found those who drank five or more cups of java a day showed a 0.43 times lower risk of estrogen-receptor negative cancers.
