Sleep Apnea Tied to Increased Cancer Risk‎‎
Two new studies have found that people with sleep apnea, a common disorder that causes snoring, fatigue and dangerous pauses in breathing at night, have a higher risk of cancer. The new research marks the first time that sleep apnea has been linked to cancer in humans.

Lung cancer tests advised for some heavy smokers‎
New recommendations from chest and cancer doctors call for lung cancer screening in older adults with a long history of smoking a pack a day or more -- but also highlight the possible harms of screening, including a high risk of false positive tests.

Sigmoidoscopy an option for colon cancer screening‎‎
Screening for colon cancer using a flexible tube -- which is less invasive and more convenient than colonoscopy -- may also help prevent new cases and deaths from the disease, a new study suggests.

Folic acid tied to lower child cancer risks‎‎
Rates of two rare childhood cancers (Wilms tumor -a type of kidney cancer-, and primary neuroectodermal tumor) declined after the U.S. began requiring grain products to be fortified with the B vitamin folic acid, a new study finds.

Cancer Research Should Be a National Priority
If a terrorist targeted almost two million Americans per year and killed over half a million of them, the U.S. would almost certainly declare war. Why, then, have we not put the same effort into fighting cancer that we have into fighting wars?
Cancer kills more people every day than terrorists killed on September 11, 2001. Yet our country fails to prioritize cancer as a national issue.

Celldex breast cancer drug (CDX-011) shrinks some tumors: study‎‎‎
Interim results from a mid-stage trial of Celldex Therapeutics Inc's experimental drug showed trends toward reducing tumors in patients with advanced breast cancer, with rates improving for those patients with high levels of a key protein.

Pancreatic Cancer Vaccine Shows Promise‎
A vaccine to treat deadly pancreatic cancer could be available within a couple years.

Panel advises against PSA cancer screening‎‎‎
Doctors should no longer offer the PSA prostate cancer screening test to healthy men because they're more likely to be harmed by the blood draw — and the chain of medical interventions that often follows — than be helped, according to government advisory panel's final report.

Art competition helps cancer patients tell their stories‎‎
The American Cancer Society reports that there are nearly 12 million cancer survivors alive today in the U.S. alone. In addition, there are millions more who love and care for them. The common thread that unites them is the fact that each person is on a cancer journey with a story to tell that can inspire others.

Professor writes about painful effects of ovarian cancer‎‎
After learning she had advanced ovarian cancer, Susan Gubar felt the need to reassure her two grown daughters that not even death could separate them.

Not Letting Cancer Define Us‎ ‎
It is how we face obstacles that define us and those obstacles can vary in size or matter. They can be trying to hit a curve ball in Little League, passing a math test or as common as trying to curb your appetite so that you can shed 10 pounds. Sometimes in life, what seems to be an obstacle is not. If you face these small obstacles with positive focus and bravery, the so-called obstacle will never define you -- in fact, you can actually define it.

Anti-Psychotic Drug Pushes Cancer Stem Cells Over the Edge‎ ‎
An anti-psychotic drug used to treat schizophrenia appears to get rid of cancer stem cells by helping them differentiate into less threatening cell types. The discovery reported in the Cell Press journal Cell on May 24th comes after researchers screened hundreds of compounds in search of those that would selectively inhibit human cancer stem cells, and it may lead rather swiftly to a clinical trial.

New clues about cancer cell metabolism emerge‎ ‎
For almost a century, researchers have known that cancer cells have peculiar appetites, devouring glucose in ways that normal cells do not. But glucose uptake may tell only part of cancer's metabolic story. Researchers from the Broad Institute and Massachusetts General Hospital looked across 60 well-studied cancer cell lines, analyzing which of more than 200 metabolites were consumed or released by the fastest dividing cells. Their research yields the first large-scale atlas of cancer metabolism and points to a key role for the smallest amino acid, glycine, in cancer cell proliferation. Their results appear in the May 25 issue of the journal Science.

Why People Stick with Cancer Screening, Even When It Causes Harm‎ ‎
When it comes to complex medical decisions, cold hard statistics may hold little sway over patients in the face of a single, compelling anecdote.

Cancer de la peau: les cabines à UV dans le collimateur du gouvernement‎‎‎‎
Face à la multiplication des cancers de la peau en France, le gouvernement a décidé de durcir la réglementation des cabines à bronzage artificiel, tenus pour responsables de plusieurs dizaines de décès chaque année par mélanomes.

Les cas de cancer de la peau en forte hausse depuis 1980 en France‎‎‎
Quelque 80.000 cancers de la peau sont signalés chaque année dans l'Hexagone, d'après des données présentées par l'Institut national du cancer (INCa), l'Institut national de prévention et d'éducation pour la santé (Inpes) et le ministère de la Santé, mercredi 23 mai. Près de 9.780 nouveaux cas de mélanomes, le plus dangereux des cancers de la peau, ont été diagnostiqués en 2011. L'incidence de cette forme de cancer de la peau a ainsi plus que triplé entre 1980 et 2005.

Cancer: des molécules "faussaires" pour doper l'effet de la radiothérapie‎
Des molécules "leurres" qui trompent les cellules cancéreuses et les poussent au suicide sont testées pour doper la radiothérapie chez des patients atteints de mélanome cutané avec présence de métastases à proximité sur la peau, selon l'Institut Curie.

Ronfler augmenterait les risques de cancer
Les personnes souffrant de troubles graves de la respiration pendant le sommeil (SDB), ont presque 5 fois plus de risques de développer un cancer.

Quand l'immunité protège aussi du cancer‎‎
AVIS D'EXPERT- Sebastian Amigorena, biologiste et membre de l'Académie des sciences nous explique que le système immunitaire peut nous protéger, au moins partiellement, contre le développement des tumeurs cancéreuses malignes.

Vers un nouveau traitement contre le cancer de la prostate‎‎‎
Des chercheurs américains ont démontré qu'un médicament, nommé le "Zytiga", avait la capacité de d'enrayer la tumeur cancéreuse chez les hommes souffrant d'un cancer de la prostate, avance Le Parisien / Aujourd'hui en France, lundi 21 mai. Cette molécule agirait en bloquant la production de testostérone.
