By Alina Selyukh, Dave Zimmerman. Reuters http://www.reuters.com/article/2011/08/19/us-seattlegenetics-idUSTRE77I5VG20110819 Doctors screen for cervical cancer too often Most doctors opt for screening women for cervical cancer more often than guidelines suggest, according to a new study. By Genevra Pittman. Reuters http://www.reuters.com/article/2011/08/19/us-cervical-cancer-idUSTRE77H6KZ20110819 Chromosomes and Cancer Aneuploidy—when the cells of an organism contain more or fewer than the standard number of chromosomes for its species—is found in greater than 90 percent of all human cancers. But how exactly it relates to cancer, and whether it is a cause or merely a consequence of genomic instability, has long been a mystery. Two new studies published today (August 18) in Science show that it’s probably both, pointing to a gene defect that can cause aneuploidy, and elucidating the disastrous effects of aneuploidy on a cell’s genome. By Jef Akst. In The Scientist http://the-scientist.com/2011/08/18/chromosomes-and-cancer/ How Caffeine Fights Cancer Caffeinated drinks may help prevent skin cancer by inhibiting a DNA repair pathway, thus killing potentially precancerous cells. By Jef Akst. In The Scientist http://the-scientist.com/2011/08/15/how-caffeine-fights-cancer/ Fast FDA Approval of Melanoma Drug The Food and Drug Administration approved an expensive new melanoma drug (vemurafenib, brand name Zelboraf) much faster than expected, giving a boost not only to that drug but also to other experimental products that may offer gene-based personalized medicine.

By Jenifer Goodwin.

Here, we explain three new theories for how cancer may form. By George Johnson. In The New-York Times http://www.nytimes.com/2011/08/16/health/16cancer.html Tiny genetic error responsible for hereditary cancer A single hereditary error in DNA can cause a key anti-cancer gene to switch off, giving a greater risk of developing cancer. By Tim Dean. In Australian Life Scientist http://www.lifescientist.com.au/article/397579/tiny_genetic_error_responsible_hereditary_cancer/ Cancers generate muscle-like contractions to spread around the body Scientists have discovered that a protein called JAK triggers contractions in tumours which allows cancer cells to squeeze though tiny spaces and spread, in research published in Cancer Cell.
