Cancer Research: Tackling 'untreatable/ brain tumors ♦ Decline in smoking rates may increase lung cancer mortality ♦ New prostate cancer treatment ♦ Improved radiation therapy for cancer

Nanotechnology and genetic interference may tackle 'untreatable/ brain tumors There are no effective available treatments for sufferers of Glioblastoma multiforme, the most aggressive and devastating form of brain tumor. Now a study may offer hope to the tens of thousands diagnosed with gliomas every year, using a nanomedical treatment first engineered to tackle ovarian cancer tumors. Continue Reading
Decline in smoking rates may increase lung cancer mortality due to inadequate screening guidelines A decline in smoking rates may mean that many people who could have benefited from early detection of lung cancer are dying because they don’t qualify for low-dose CT scans. Continue Reading
New target for prostate cancer treatment  A promising new therapeutic target for prostate cancer has been found by researchers, offering evidence that a newly discovered member of a family of cell surface proteins called G-protein coupled receptors promotes prostate cancer cell growth. Continue Reading
'DNA spellchecker' means that genes aren't all equally likely to mutate  A study that examined 17 million mutations in the genomes of 650 cancer patients concludes that large differences in mutation rates across the human genome are caused by the DNA repair machinery. 'DNA spellchecker' is preferentially directed towards more important parts of chromosomes that contain key genes. The study illustrates how data from medical sequencing projects can answer basic questions about how cells work.Continue Reading

Effect improves radiation therapy for patients with cancer The complex parts of the blue light known as the Cherenkov Effect can be measured and used in dosimetry to make therapies safer and more effective, scientists report. Continue Reading
