Dialogue: 0,0:00:32.28,0:00:34.78,Default,,0000,0000,0000,,Now, I will argue that a primary reason

Dialogue: 0,0:00:36.94,0:00:39.24,Default,,0000,0000,0000,,is because we're fighting blindly.

Dialogue: 0,0:00:47.27,0:00:49.13,Default,,0000,0000,0000,,And not just any type of brain cancer:
Dialogue: 0,0:00:49.14,0:00:52.32,Default,,0000,0000,0000,,he was diagnosed with one\Nof the most deadly forms of brain cancer.
Dialogue: 0,0:00:52.34,0:00:53.56,Default,,0000,0000,0000,,In fact, it was so deadly
Dialogue: 0,0:00:53.58,0:00:56.24,Default,,0000,0000,0000,,that the doctors told him\Nthat they only have 12 months,

Dialogue: 0,0:01:04.17,0:01:05.63,Default,,0000,0000,0000,,Now, the good news, they said,
Dialogue: 0,0:01:05.65,0:01:08.58,Default,,0000,0000,0000,,is that there are tons\Nof different treatments to choose from,
Dialogue: 0,0:01:08.58,0:01:09.80,Default,,0000,0000,0000,,but the bad news is
Dialogue: 0,0:01:09.82,0:01:13.36,Default,,0000,0000,0000,,that in order for them to tell\Nif a treatment is even working or not,
Dialogue: 0,0:01:13.36,0:01:15.86,Default,,0000,0000,0000,,well, that takes them\Nabout three months or so.
Dialogue: 0,0:01:15.87,0:01:18.25,Default,,0000,0000,0000,,So they cannot try that many things.
Dialogue: 0,0:01:18.25,0:01:21.35,Default,,0000,0000,0000,,Well, Ehud is now going\Ninto his first treatment,
Dialogue: 0,0:01:21.35,0:01:24.61,Default,,0000,0000,0000,,and during that first treatment,\Njust a few days into that treatment,
Dialogue: 0,0:01:24.63,0:01:27.97,Default,,0000,0000,0000,,I'm meeting with him, and he tells me,\N"Adam, I think this is working.

Dialogue: 0,0:01:30.81,0:01:33.27,Default,,0000,0000,0000,,And I ask him, "Really?\NHow do you know that, Ehud?"
Dialogue: 0,0:01:33.29,0:01:35.51,Default,,0000,0000,0000,,And he says, "Well,\NI feel so terrible inside.

Dialogue: 0,0:01:38.63,0:01:43.07,Default,,0000,0000,0000,,Well, unfortunately, three months later,\Nwe got the news, it didn't work.
Dialogue: 0,0:01:44.02,0:01:46.08,Default,,0000,0000,0000,,And so Ehud goes\Ninto his second treatment.
Dialogue: 0,0:01:46.10,0:01:47.36,Default,,0000,0000,0000,,And again, the same story.

Dialogue: 0,0:01:50.13,0:01:53.07,Default,,0000,0000,0000,,And then three months later,\Nagain we get bad news.
Dialogue: 0,0:01:53.09,0:01:57.03,Default,,0000,0000,0000,,Ehud is going into his third treatment,\Nand then his fourth treatment.
Dialogue: 0,0:01:57.03,0:01:59.55,Default,,0000,0000,0000,,And then, as predicted, Ehud dies.
Dialogue: 0,0:02:00.42,0:02:04.100,Default,,0000,0000,0000,,Now, when someone really close to you\Nis going through such a huge struggle,
Dialogue: 0,0:02:05.01,0:02:06.83,Default,,0000,0000,0000,,you get really swamped with emotions.
Dialogue: 0,0:02:06.83,0:02:08.92,Default,,0000,0000,0000,,A lot of things\Nare going through your head.
Dialogue: 0,0:02:08.93,0:02:10.39,Default,,0000,0000,0000,,For me, it was mostly outrage.
Dialogue: 0,0:02:10.40,0:02:15.10,Default,,0000,0000,0000,,I was just outraged that, how come\Nthis is the best that we can offer?
Dialogue: 0,0:02:15.12,0:02:17.42,Default,,0000,0000,0000,,And I started looking\Nmore and more into this.
Dialogue: 0,0:02:17.42,0:02:20.88,Default,,0000,0000,0000,,As it turns out, this is not just\Nthe best that doctors could offer Ehud.
Dialogue: 0,0:02:20.89,0:02:24.71,Default,,0000,0000,0000,,It's not just the best doctors could offer\Npatients with brain cancer generally.
Dialogue: 0,0:02:24.72,0:02:27.92,Default,,0000,0000,0000,,We're actually not doing that well\Nall across the board with cancer.
Dialogue: 0,0:02:28.72,0:02:30.58,Default,,0000,0000,0000,,I picked up one of those statistics,
Dialogue: 0,0:02:30.58,0:02:33.36,Default,,0000,0000,0000,,and I'm sure some of you\Nhave seen those statistics before.
Dialogue: 0,0:02:33.37,0:02:36.83,Default,,0000,0000,0000,,This is going to show you here\Nhow many patients actually died of cancer,
Dialogue: 0,0:02:36.83,0:02:38.85,Default,,0000,0000,0000,,in this case females in the United States,
Dialogue: 0,0:02:38.86,0:02:40.16,Default,,0000,0000,0000,,ever since the 1930s.
Dialogue: 0,0:02:40.16,0:02:43.34,Default,,0000,0000,0000,,You'll notice that there aren't\Nthat many things that have changed.
Dialogue: 0,0:02:43.34,0:02:44.64,Default,,0000,0000,0000,,It's still a huge issue.
Dialogue: 0,0:02:44.65,0:02:46.39,Default,,0000,0000,0000,,You'll see a few changes though.
Dialogue: 0,0:02:46.39,0:02:48.93,Default,,0000,0000,0000,,You'll see lung cancer,\Nfor example, on the rise.
Dialogue: 0,0:02:48.95,0:02:50.15,Default,,0000,0000,0000,,Thank you, cigarettes.
Dialogue: 0,0:02:50.94,0:02:53.44,Default,,0000,0000,0000,,And you'll also see that,\Nfor example, stomach cancer
Dialogue: 0,0:02:53.44,0:02:56.78,Default,,0000,0000,0000,,once used to be one\Nof the biggest killers of all cancers,
Dialogue: 0,0:02:56.79,0:02:58.23,Default,,0000,0000,0000,,is essentially eliminated.
Dialogue: 0,0:02:58.84,0:03:00.90,Default,,0000,0000,0000,,Now, why is that?\NAnyone knows, by the way?
Dialogue: 0,0:03:00.92,0:03:04.26,Default,,0000,0000,0000,,Why is it that humanity is no longer\Nstruck by stomach cancer?
Dialogue: 0,0:03:04.27,0:03:09.13,Default,,0000,0000,0000,,What was the huge, huge\Nmedical technology breakthrough
Dialogue: 0,0:03:09.14,0:03:12.50,Default,,0000,0000,0000,,that came to our world\Nthat saved humanity from stomach cancer?
Dialogue: 0,0:03:13.71,0:03:17.53,Default,,0000,0000,0000,,Was it maybe a new drug,\Nor a better diagnostic?
Dialogue: 0,0:03:17.53,0:03:18.83,Default,,0000,0000,0000,,You guys are right, yeah.
Dialogue: 0,0:03:18.85,0:03:21.47,Default,,0000,0000,0000,,It's the invention of the refrigerator,
Dialogue: 0,0:03:21.47,0:03:24.09,Default,,0000,0000,0000,,and the fact that we're\Nno longer eating spoiled meats.
Dialogue: 0,0:03:24.10,0:03:26.40,Default,,0000,0000,0000,,So the best thing\Nthat happened to us so far
Dialogue: 0,0:03:26.41,0:03:28.35,Default,,0000,0000,0000,,in the medical arena in cancer research
Dialogue: 0,0:03:28.36,0:03:30.55,Default,,0000,0000,0000,,is the fact that\Nthe refrigerator was invented.
Dialogue: 0,0:03:30.58,0:03:31.78,Default,,0000,0000,0000,,(Laughter)
Dialogue: 0,0:03:31.79,0:03:33.05,Default,,0000,0000,0000,,And so -- yeah, I know.
Dialogue: 0,0:03:33.07,0:03:34.49,Default,,0000,0000,0000,,We're not doing so well here.
Dialogue: 0,0:03:34.49,0:03:36.83,Default,,0000,0000,0000,,I don't want to miniaturize the progress
Dialogue: 0,0:03:36.84,0:03:40.22,Default,,0000,0000,0000,,and everything that's been done\Nin cancer research.
Dialogue: 0,0:03:40.42,0:03:43.84,Default,,0000,0000,0000,,Look, there is like 50-plus years\Nof good cancer research
Dialogue: 0,0:03:43.84,0:03:47.26,Default,,0000,0000,0000,,that discovered major, major things\Nthat taught us about cancer.
Dialogue: 0,0:03:47.27,0:03:49.01,Default,,0000,0000,0000,,But all that said,
Dialogue: 0,0:03:49.01,0:03:51.58,Default,,0000,0000,0000,,we have a lot of heavy lifting\Nto still do ahead of us.
Dialogue: 0,0:03:53.31,0:03:56.41,Default,,0000,0000,0000,,Again, I will argue that the primary\Nreason why this is the case,
Dialogue: 0,0:03:56.43,0:03:58.43,Default,,0000,0000,0000,,why we have not done that remarkably well,
Dialogue: 0,0:03:58.46,0:04:00.30,Default,,0000,0000,0000,,is really we're fighting blindly here.
Dialogue: 0,0:04:00.31,0:04:02.53,Default,,0000,0000,0000,,And this is where\Nmedical imaging comes in.
Dialogue: 0,0:04:02.53,0:04:04.21,Default,,0000,0000,0000,,This is where my own work comes in.
Dialogue: 0,0:04:04.93,0:04:07.67,Default,,0000,0000,0000,,And so to give you a sense\Nof the best medical imaging
Dialogue: 0,0:04:07.67,0:04:10.17,Default,,0000,0000,0000,,that's offered today\Nto brain cancer patients,
Dialogue: 0,0:04:10.17,0:04:12.34,Default,,0000,0000,0000,,or actually generally\Nto all cancer patients,
Dialogue: 0,0:04:12.35,0:04:14.29,Default,,0000,0000,0000,,take a look at this PET scan right here.
Dialogue: 0,0:04:14.29,0:04:15.53,Default,,0000,0000,0000,,Let's see. There we go.
Dialogue: 0,0:04:16.15,0:04:17.85,Default,,0000,0000,0000,,So this is a PET/CT scan,
Dialogue: 0,0:04:17.87,0:04:20.32,Default,,0000,0000,0000,,and what you'll see in this PET/CT scan
Dialogue: 0,0:04:20.35,0:04:23.57,Default,,0000,0000,0000,,is the CT scan will show you\Nwhere the bones are,
Dialogue: 0,0:04:23.58,0:04:25.98,Default,,0000,0000,0000,,and the PET scan will show you\Nwhere tumors are.
Dialogue: 0,0:04:26.34,0:04:28.56,Default,,0000,0000,0000,,Now, what you can see here
Dialogue: 0,0:04:28.56,0:04:30.98,Default,,0000,0000,0000,,is essentially a sugar molecule
Dialogue: 0,0:04:30.99,0:04:32.81,Default,,0000,0000,0000,,that was added a small little tag
Dialogue: 0,0:04:32.81,0:04:34.91,Default,,0000,0000,0000,,that is signaling to us\Noutside of the body,
Dialogue: 0,0:04:34.91,0:04:36.21,Default,,0000,0000,0000,,"Hey, I'm here."
Dialogue: 0,0:04:36.23,0:04:40.05,Default,,0000,0000,0000,,And those sugar molecules are injected\Ninto these patients by the billions,
Dialogue: 0,0:04:40.05,0:04:41.75,Default,,0000,0000,0000,,and they're going all over the body
Dialogue: 0,0:04:41.75,0:04:43.83,Default,,0000,0000,0000,,looking for cells\Nthat are hungry for sugar.
Dialogue: 0,0:04:44.73,0:04:47.39,Default,,0000,0000,0000,,You'll see that the heart,\Nfor example, lights up there.
Dialogue: 0,0:04:47.39,0:04:49.61,Default,,0000,0000,0000,,That's because the heart\Nneeds a lot of sugar.
Dialogue: 0,0:04:49.61,0:04:51.94,Default,,0000,0000,0000,,You'll also see that the bladder\Nlights up there.
Dialogue: 0,0:04:51.94,0:04:54.56,Default,,0000,0000,0000,,That's because the bladder\Nis the thing that's clearing
Dialogue: 0,0:04:54.56,0:04:55.96,Default,,0000,0000,0000,,the sugar away from our body.
Dialogue: 0,0:04:56.83,0:04:58.83,Default,,0000,0000,0000,,And then you'll see a few other hot spots,
Dialogue: 0,0:04:58.83,0:05:00.44,Default,,0000,0000,0000,,and these are in fact the tumors.
Dialogue: 0,0:05:00.45,0:05:02.59,Default,,0000,0000,0000,,Now, this is a really\Na wonderful technology.
Dialogue: 0,0:05:02.60,0:05:05.74,Default,,0000,0000,0000,,For the first time it allowed us\Nto look into someone's body
Dialogue: 0,0:05:05.75,0:05:08.13,Default,,0000,0000,0000,,without picking up\Neach and every one of the cells
Dialogue: 0,0:05:08.14,0:05:09.100,Default,,0000,0000,0000,,and putting them under the microscope,
Dialogue: 0,0:05:09.100,0:05:13.01,Default,,0000,0000,0000,,but in a noninvasive way\Nallowing us to look into someone's body
Dialogue: 0,0:05:13.02,0:05:15.16,Default,,0000,0000,0000,,and ask, "Hey,\Nhas the cancer metastasized?
Dialogue: 0,0:05:15.16,0:05:16.37,Default,,0000,0000,0000,,Where is it?"
Dialogue: 0,0:05:16.37,0:05:18.87,Default,,0000,0000,0000,,And the PET scans here\Nare showing you very clearly
Dialogue: 0,0:05:18.87,0:05:21.15,Default,,0000,0000,0000,,where are these hot spots,\Nwhere is the tumor.
Dialogue: 0,0:05:22.14,0:05:25.44,Default,,0000,0000,0000,,So as miraculous as this might seem,
Dialogue: 0,0:05:25.46,0:05:28.34,Default,,0000,0000,0000,,unfortunately, well, it's not that great.
Dialogue: 0,0:05:29.10,0:05:31.18,Default,,0000,0000,0000,,You see, those\Nsmall little hot spots there.
Dialogue: 0,0:05:31.90,0:05:35.42,Default,,0000,0000,0000,,Can anyone guess how many cancer cells\Nare in any one of these tumors?
Dialogue: 0,0:05:37.29,0:05:39.63,Default,,0000,0000,0000,,So it's about 100 million cancer cells,
Dialogue: 0,0:05:39.64,0:05:42.34,Default,,0000,0000,0000,,and let me make sure\Nthat this number sunk in.

Dialogue: 0,0:05:46.29,0:05:50.39,Default,,0000,0000,0000,,there needs to be\Nat least 100 million cancer cells

Dialogue: 0,0:05:51.93,0:05:54.39,Default,,0000,0000,0000,,Now, if that seemed to you\Nlike a very large number,
Dialogue: 0,0:05:54.41,0:05:56.09,Default,,0000,0000,0000,,it is a very large number.
Dialogue: 0,0:05:57.28,0:05:59.34,Default,,0000,0000,0000,,This is in fact\Nan incredibly large number,
Dialogue: 0,0:05:59.34,0:06:02.68,Default,,0000,0000,0000,,because what we really need\Nin order to pick up something early enough
Dialogue: 0,0:06:02.68,0:06:05.61,Default,,0000,0000,0000,,to do something about it,\Nto do something meaningful about it,
Dialogue: 0,0:06:05.63,0:06:08.77,Default,,0000,0000,0000,,well, we need to pick up tumors\Nthat are a thousand cells in size,

Dialogue: 0,0:12:07.26,0:12:10.22,Default,,0000,0000,0000,,And I think,\Nwhere medical imaging is heading to,
Dialogue: 0,0:12:10.24,0:12:12.52,Default,,0000,0000,0000,,is the ability to look\Ninto the human body
Dialogue: 0,0:12:12.55,0:12:16.70,Default,,0000,0000,0000,,and actually see each\Nand every one of these cells separately.
Dialogue: 0,0:12:16.78,0:12:18.83,Default,,0000,0000,0000,,The ability like this would allow us
Dialogue: 0,0:12:18.86,0:12:21.37,Default,,0000,0000,0000,,to pick up tumors way early\Nin the process
Dialogue: 0,0:12:21.38,0:12:23.86,Default,,0000,0000,0000,,way before it's a hundred million\Ncells in size,
Dialogue: 0,0:12:23.87,0:12:25.92,Default,,0000,0000,0000,,so we can actually do something about it.
Dialogue: 0,0:12:25.97,0:12:28.56,Default,,0000,0000,0000,,An ability to see each and every one\Nof the cells
Dialogue: 0,0:12:28.57,0:12:30.89,Default,,0000,0000,0000,,might also allow us to ask\Ninsightful questions.
Dialogue: 0,0:12:30.93,0:12:32.94,Default,,0000,0000,0000,,So in the lab,\Nwe're now getting to a point
Dialogue: 0,0:12:33.01,0:12:36.22,Default,,0000,0000,0000,,where we can actually start asking\Nthese cancer cells real questions
Dialogue: 0,0:12:36.24,0:12:39.97,Default,,0000,0000,0000,,like, for example, are you responding\Nto the treatment we're giving you or not?
Dialogue: 0,0:12:39.100,0:12:42.93,Default,,0000,0000,0000,,If you're not, we will know\Nto stop the treatment right away -

Dialogue: 0,0:12:46.23,0:12:48.10,Default,,0000,0000,0000,,Also for patients like Ehud,

Dialogue: 0,0:12:52.82,0:12:56.90,Default,,0000,0000,0000,,For them not to suffer through\Nthose horendous side effects of the drugs,
Dialogue: 0,0:12:56.98,0:12:59.73,Default,,0000,0000,0000,,when drugs are in fact\Nnot even helping them.
Dialogue: 0,0:13:01.90,0:13:03.12,Default,,0000,0000,0000,,So to be frank here,
Dialogue: 0,0:13:03.16,0:13:06.62,Default,,0000,0000,0000,,we're pretty far away\Nfrom winning the war against cancer,
Dialogue: 0,0:13:06.64,0:13:07.90,Default,,0000,0000,0000,,just to be realistic.
Dialogue: 0,0:13:07.92,0:13:09.82,Default,,0000,0000,0000,,But at least I am hopeful
Dialogue: 0,0:13:09.84,0:13:13.98,Default,,0000,0000,0000,,that we should be able to fight this war\Nwith better medical imaging techniques
