but I don't buy that.
mais je n'y crois pas.
anyone here will question that.
que quiconque ici en doute.
qu'une des raisons principales
this war against cancer
a story about a good friend of mine.
l'histoire d'un bon ami à moi.
Ehud was diagnosed with brain cancer.
de cancer du cerveau.
of the most deadly forms of brain cancer.
une des formes les plus mortelles.
that they only have 12 months,
qu'il n'avait que 12 mois
they have to find a treatment.
ils devaient trouver un traitement.
find a cure, he will die.
of different treatments to choose from,
parmi lesquels choisir,
if a treatment is even working or not,
si un traitement fonctionnait,
about three months or so.
faire beaucoup d'essais.
into his first treatment,
just a few days into that treatment,
après seulement quelques jours,
"Adam, I think this is working.
« Adam, je crois que cela fonctionne.
Something is happening."
Il se passe quelque chose. »
How do you know that, Ehud?"
Comment le sais-tu ? »
I feel so terrible inside.
si mal à l'intérieur.
we got the news, it didn't work.
que cela ne fonctionnait pas.
into his second treatment.
gotta be working there."
quelque chose doit fonctionner. »
again we get bad news.
nous avons appris la mauvaise nouvelle.
and then his fourth treatment.
puis son quatrième traitement.
is going through such a huge struggle,
traverse un moment très dur,
are going through your head.
vous traversent l'esprit.
this is the best that we can offer?
le mieux que nous ayons à offrir.
more and more into this.
the best that doctors could offer Ehud.
que les docteurs pouvaient offrir à Ehud
patients with brain cancer generally.
aux patients atteint d'un cancer.
all across the board with cancer.
nous ne nous en sortons pas bien.
have seen those statistics before.
ont sûrement déjà vue.
how many patients actually died of cancer,
combien de patients sont morts du cancer,
that many things that have changed.
que peu de choses ont changé.
for example, on the rise.
du cancer du poumon.
for example, stomach cancer
le cancer de l'estomac
of the biggest killers of all cancers,
les plus mortels,
Anyone knows, by the way?
struck by stomach cancer?
plus atteinte de cancer de l'estomac ?
medical technology breakthrough
la technologie médicale
that saved humanity from stomach cancer?
du cancer de l'estomac ?
or a better diagnostic?
ou un meilleur diagnostic ?
no longer eating spoiled meats.
de viandes avariées.
that happened to us so far
contre le cancer
the refrigerator was invented.
in cancer research.
comme recherches sur le cancer.
of good cancer research
de bonne recherche sur le cancer
that taught us about cancer.
majeures sur le cancer.
to still do ahead of us.
de travail à accomplir.
reason why this is the case,
la raison principale de notre échec
medical imaging comes in.
entre en jeu,
of the best medical imaging
de la meilleure imagerie médicale
to brain cancer patients,
de cancer du cerveau
to all cancer patients,
where the bones are,
où sont les os
where tumors are.
où sont les tumeurs.
outside of the body,
à nous à l'extérieur du corps :
into these patients by the billions,
par milliards dans le patient
that are hungry for sugar.
voulant du sucre.
for example, lights up there.
que le cœur s'éclaire ici
needs a lot of sugar.
lights up there.
is the thing that's clearing
a wonderful technology.
to look into someone's body
de voir l'intérieur du corps
each and every one of the cells
allowing us to look into someone's body
de regarder l'intérieur du corps
has the cancer metastasized?
are showing you very clearly
where is the tumor.
small little hot spots there.
are in any one of these tumors?
cancéreuses sont composées les tumeurs ?
de cellules cancéreuses.
that this number sunk in.
que vous perceviez bien cela.
of these small little blips
at least 100 million cancer cells
100 millions de cellules cancéreuses
like a very large number,
un nombre important,
an incredibly large number,
in order to pick up something early enough
afin de détecter quelque chose assez tôt
to do something meaningful about it,
faire quelque chose de significatif,
that are a thousand cells in size,
qui font un millier de cellules
a handful of cells in size.
seulement quelques cellules.
pretty far away from this.
a little experiment here.
to now play and imagine
de jouer et d'imaginer
that the tumor is out.
que la tumeur est enlevée.
have already been removed,
about the size of a golf ball or so
de la taille d'une balle de golf
of this person's brain.
everything looks the same,
tout se ressemble
and healthy brain tissue
et le tissu cérébral sain
a little bit on the brain,
a little harder, stiffer,
sont un peu plus dures, rigides
a little bit like this and say,
vous faites un peu comme cela,
and start cutting the tumor
et retirez la tumeur,
to a stage where you think,
I took out everything."
like, pretty crazy --
challenging decision of your life here.
la plus difficile de votre vie.
and let this patient go,
laisser le patient partir,
some leftover cancer cells behind
des cellules cancéreuses
around the tumor
have to take every single day
doivent faire chaque jour
to a few friends of mine in the lab,
à des amis au labo et avoir dit :
there's got to be a better way."
une meilleure façon de faire. »
that there's got to be a better way.
qu'il doit y avoir une meilleure solution.
the sugar and so on.
dont je vous ai parlé, avec le sucre.
instead of using sugar molecules,
little particles made of gold,
de petites particules d'or
interesting chemistry around them.
les cellules cancéreuses.
to look for cancer cells.
these gold particles
ces particules d'or
every single cell in our body
or are you a healthy cell?
cancéreuse ou saine.
we're sticking in and shining out
la particule reste, brille
"Hey, look at me, I'm here."
« Regardez-moi, je suis là. »
through some interesting cameras
grâce à des caméras
maybe we can guide brain cancer surgeons
nous pouvons guider les neurochirurgiens
and leaving the healthy brain alone.
sans toucher au cerveau sain.
and boy, this works well.
cela fonctionne bien.

dans le cerveau de cette souris.
growing in this mouse's brain,
and asked the doctor
as if that was a patient,
comme si c'était un patient
out of the tumor.
morceau par morceau.
to see where the gold particles are.
pour voir où sont les particules d'or.
into this mouse,
dans la souris,
right here at the very left there
where the gold particles are.
où sont les particules d'or.
c'est que les particules d'or
is that these gold particles
"Hey, we're here. Here's the tumor."
« Nous sommes là. La tumeur est là. »
to the doctor yet.
pas encore au docteur.
now please start cutting away the tumor,
d'enlever la tumeur,
just took the first quadrant of the tumor
que le premier quart de la tumeur
is now missing.
the second quadrant, the third,
le deuxième, le troisième
the doctor came back to us and said,
What do you want me to do?
que je fasse ?
some extra margins around?"
une marge supplémentaire ? »
"You've missed those two spots,
« Vous avez oublié ces deux endroits,
and then let's take a look."
and lo and behold,
that the cancer is completely gone
ait complètement disparu
huge amounts of healthy brain
trop de cerveau sain
as they take away a tumor,
en enlevant les tumeurs,
have to guess with their thumb.
d'utiliser leur pouce.
to take those tiny little leftover tumors.
d'enlever ces restes de tumeur.
even if it's just a handful of cells,
même si ce ne sont que quelques cellules,

est ma vision de la direction prise.
what should we be working on now?
ce sur quoi nous devrions travailler.
medical imaging is heading to

way, way earlier in the process,
bien, bien plus tôt,
so we can actually do something about it.
afin de pouvoir agir.

toutes ces cellules nous permettrait
we are now getting to a point
these cancer cells real questions,
aux cellules cancéreuses,
to the treatment we are giving you or not?
au traitement qui leur est donné.
to stop the treatment right away,
nous pourrons l'arrêter immédiatement,
