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.

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.

Doctors

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.

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.

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.
