Computer-aided mammography doesn't improve breast cancer detection
The widely used mammography software known as computer-aided detection
(CAD) doesn't improve detection of invasive breast cancer, new
research suggests. By Kathleen Doheny. In USA Today

Screening has little impact on breast cancer deaths: study‎
Falling breast cancer death rates have little to do with breast
screening but are down to better treatment and health systems,
scientists said on Friday, in a study likely to fuel a long-running
row over the merits of mammograms.

Scant Evidence to Link 9/11 to Cancer, US Report Says
There is not enough evidence yet to say whether the dust and smoke
cloud produced by the terrorist attack on the World Trade Center
caused cancer, federal officials concluded in a report released on
Tuesday.

Convergence in head and neck cancer
In back-to-back papers published online July 28 in Science,
researchers from the Broad Institute, Dana-Farber Cancer Institute,
Johns Hopkins Kimmel Cancer Center, the University of Pittsburgh, and
the University of Texas MD Anderson Cancer Center have confirmed
genetic abnormalities previously suspected in head and neck cancer,
including defects in the tumor suppressor gene known as p53. But the
two teams also found mutations in the NOTCH family of genes,
suggesting their role as regulators of an important stage in cell
development may be impaired.

Researchers Look to Dogs to Better Understand Intricacies of Bone
Cancer
A new University of Minnesota discovery may help bone cancer patients
fight their disease more effectively, according to new research
published in the September issue of “Bone”. In Science Daily

Are Cancers New Species?
Cancer is one of the scourges of modern society. An increasing number
of people are fighting it, and a lot of research is being done in
order to understand it better, hopefully leading to treatments or
cures.
At present, the dominant theory is that cancer arises from a handful
gene mutations. But recently, Peter Duesberg and his colleagues at UC
Berkeley have launched the idea that cancer instead arises from
chromosome disruptions, and that this, in fact, constitutes a form of
speciation. So, according to this view, cancers are newly evolved
species, as they have new chromosomal karyotypes. On top of this,
cancers are autonomous and don’t need other cells for survival.

Growing Up Near Livestock Tied to Blood Cancers
Children raised on livestock farms are at significantly greater risk
of developing blood cancers -- such as leukemia, multiple myeloma and
non-Hodgkin's lymphoma -- later in life, a new study contends. In U.S.

Cancer mystery solved
Same protein (maspin) can slow disease or put it on fast track.

Early-stage breast cancer: Microscopic tumor spread is no worry
Women with early-stage breast cancer have plenty of procedures and
treatments to deal with. So it may come as welcome news that a large
clinical trial has found no reason for doctors to perform two tests
that were thought to help predict patient survival. Writing in the
Journal of the American Medical Assn., the researchers say that the
test results are meaningless.

Researchers Find 3 Genes (MSR1, ASCC1, and CTHRC1) Linked to Esophagus
Disorders
Mutations in three genes have been found to be more common among
people with disorders of the esophagus, including esophageal cancer
and Barrett esophagus (a complication of gastroesophageal reflux
disease), a new study shows. In U.S. News & World Report

Can the cat give you cancer? Parasite in their bellies linked with
brain tumours
Scientists have found a link between brain tumours and a parasite that
is found in both cats' stomachs and humans.

Pas de lien entre le 11/09 et des cancers
Il n'existe pas de preuve que l'exposition aux poussières et aux
décombres du World Trade Center après les attentats du 11 septembre
2001 à New York ait entraîné de nombreux cas de cancers, affirme un
rapport du gouvernement américain.

Plan cancer: à mi-parcours, Sarkozy exhorte à "ne pas relâcher
l'effort"
Nicolas Sarkozy a souligné "la poursuite des avancées obtenues dans la
lutte contre le cancer" et appelé "à ne pas relâcher l'effort,
notamment en matière de prévention et de dépistage", en recevant lundi
un nouveau rapport d'étape sur le plan cancer 2009-2013.

Cancer de la prostate résistant : la testostérone est court-circuitée
Des chercheurs texans ont identifié un mécanisme de résistance à la
castration hormonale dans les cancers de la prostate. La
dihydrotestostérone (DHT), puissant androgène, continuerait à être
synthétisée par une voie alternative indépendante de la testostérone.
