ferrell, pardon me, stay classy, i'm sorry. >> time to musk up. >> that does it for us. have a wonderful labor day weekend. >> stick around. eric shawn and molly line are in with the doctors coming up next. >> we're back at 4:00 p.m. eastern. hi. i'm eric shawn. time for "sunday housecall." >> and i'm molly line in for or they will neville. joining us dr. david samadi, chairman and professor of urology at lennox hill hospital and chief of robotics surgery. >> and dr. marc sgeel, professor of medicine at nyu's langone medicine and author of "the secret code, unlocking the sacred code of sickness and health." >> scientists say they have discovered a blood test that can detect breast cancer dna months, they say, before it will show up on medical scans. dr. siegel, can you get this

now, and how important is this? >> can you not get this now. it's in early stages of research, but the research is extremely promising. it's coming out of london this study. they looked at 55 people, and they first analyzed the dna, eric, that was abnormal, in the tumor itself. they took early tumors, and they said here's what the mutations are because all cancer has mutations. it has dna that went awry. the cell's machinery is going awry and that's why you get this rapidly growing tumor so they isolated it, which is expensive, and then created a blood test to follow the blood of these women to see if the breast cancer rekurd. the blood test is cheap. the initial analysis of the tumor is expensive. now, here's what they found. of the 15 people that had recurrences of breast cancer, they found it early in 12 out of the 15, and the other three that had spread to the brain where they may not have been able to find it in the blood anyway. you know what that means. that means in the future we may be able to know that breast

cancer or any cancer is spreading before it actually spreads. we may be able to predict it and give treatment in advance. >> this seems like type of thing that might even be a watershed and looking into the study one of the things that they also said the tests revealed if something was drug resistant to mutations, if the cancer was drug resistant. is that a big part of this as well? >> it is a huge discovery, and when it comes to our clinical trials, it can change -- has potential to change the way we practice medicine. for a lot of people just so that you understand what's going on here. -for-diagnosis we're now doing a biopsy and removing part of the tissue, so if you want to get liver biopsy, prostate booips biopsy, breast biopsy. we're sampling tissue and now we're talking about liquid biopsy meaning the cells from cancer cells are floating in the blood and just getting a blood test we're able to see if the cancer cells are actually floating in your blood. >> can they do that right now? >> this test is not available but it will come in the future. now, we've talked about me fast

sis, what happens when the cell actually leaves the first island or the first organ and floats through this river which is your blood and lands somewhere else and so we can detect metastasis earlier and we can find thetati. if you give -- let's say you do surgery or chemotherapy, is our treatment really working or not? is there recurrence in the blood that we're not able to see? now, on other side of this, we're checking with cat scans and mris. that's why, for example, i removed the pros tape. we're going to find out if somebody has a problem by getting a bone scan or cat scan or images, but what if the cancer is not big enough to show up on cat scan and it's just floating in the blood. now you'll be able to do this through the liquid biopsies which is a big discovery. >> to emphasize one point here is if i knew in advance that a cancer was going to come back in someone i might institute immunotherapy or chemotherapy or radiation therapy in advance and prevent it from ever actually coming back. >> or even change the regiment that you're using in case --

which is what you were trying to bring up. >> more advanced, more aggressive. >> if there's a mutation, now we can change exactly what our treatment option is going to be and say, look, this chemotherapy won't work for you. we'll have a different plan. this is a game-chaim changer for us. >> that's the drug resistant part you're pointing out. >> a possible breakthrough in ovarian cancer, beta blockers being looked at and heart medications may have a bigger role in fighting that cancer, another study and beta blockers were linked in a more than four--year long inquiry for survival in women with owe vhfian cancer. >> in some places we find this coincident kind of studies. this is one of them. ovarian cancers, about 21,000 cases a year and 14,000 deaths and there's no real symptoms and by the time you find the cancer it's in advanced stage and what they found was in a series of these patients who have been taking beta blockers, what is beta blocker for people who have arrhythmia and high blood

pressure, their heart is basically pumping too fast, medications that calms down the heart and also takes away a lot of these hormones like epinephrine can also slow down the progression of the disease with ovarian cancer. those patients that have advanced ovarian cancer live four years longer when they were on beta blockers, and these are non-selective beta blockers. what's the message to a lot of people out there? i think you should have a conversation with your doctor. don't want everyone to go out there and say dr. samadi says i should be on beta blockers. patient selection and you should have a conversation. >> a few points to add on this. one is that ovarian cancer emphasized the point very difficult to diagnose. by the time we find it, 14,000 deaths, 21,000 whimper year diagnosed with it, 14,000 deaths, because it's spread around by the time we get to it so the idea of having a drug that may prolong life in someone with severe ovarian cancer by

four years is very exciting, but as david mentioned we don't know that yet. that's not proof here. what we call this is an association. reason we can't tell women to take beta blockers with ovarian cancer is we don't know why this is happening. is it because the beta blocker dialates your arteries and because it blunts the stress hormones that david was mentioning, adrenaline, is that the reason? this is an invitation for further study to see if we give one great the beta blocker and one group doesn't get the beta belo beloki. that's the real science and a tool that we can use. >> excellent point brought up and i'm glad. we need a more prospective study to really find out what's going on and going back to the first top take we were talking about, imagine we would have the liquid biopsy for ovarian cancer and can you catch these patients eight months to a year before that actually can me fast size, it's tremendous, but i think your point is very important, and people should not say, hey, i should go on these beta

blockers because it's just an interesting finding, but we need a longer and bigger group to study. >> we'll waited for that. >> well, you know, talked a lot on this program about low vitamin d levels and now there's questions as to whether that's connected to multiple sclerosis. we'll take a look at a new study. and have you seen a new federal report that says school lunches are becoming more healthier. what are kids eating, what should they eat and why are we told they are eating better? why do so many people choose aleve? it's the brand more doctors recommend for minor arthritis pain. plus, just two aleve can last all day. you'd need 6 tylenol arthritis to do that. aleve. all day strong. irresistible moments deserve irresistibles treats.

wires. the white matter of the brain, your immune system attacks it and starts to scar it and we don't know why that occur. no one has ever been able to show why that occurs but more and more evidence shows vitamin d may play a role, another reason and david and i have talked about this on the show, get your vitamin d level checked, especially if you're in northern climates, northern european, may not be getting enough vitamin d. i love vitamin d supplements, half my patients taking them. >> men and women? ? men and women, and children and a lot of studies coming from netherlands showing the kids exposed to sun and they had adequate vitamin d, lower chance of getting multiple sclerosis. we're finding out more and more that vitamin d is really not a vitamin but it acts like a real hormone in the body. we've seen it behave towards parkinson's and towards colon cancer and pros kate cancer so it's really involved in a lot of immune part of our body and ms,

an autoimmune disease, attacking the wrapping around the nerves, and so taking and knowing what your vitamin d is extremely critical, and we can measure this. we can get a blood test and check your vitamin d. the big question is how much vitamin d should you be taking and who are real exposed? we've seen that pregnant women, people not exposed to sun, those who have really low vitamin d and once you know your level which should be over 0 then we can supplement the vitamin d and make sure you bring it to the level. the other thing, i'm sorry, molly, what they found is when your vitamin d level is higher, your fatigue symptoms is actually a lot less which is very interesting, so there's more to this story in the future. >> by the way, you're getting a heck of a lot of vitamin d from sunlight and i'm not advertising it and you get more than 50 times the amount of vitamin d that you need in more than half an hour of direct sunlight. >> three times a week and 15

do you think it will make a big difference for young kids? are they dumping fruits and vegetables in the trash? >> i think that's true. i did a report on a solution to this. the good news is cdc says 80% of schools are putting two or more vegetable or fruit on every plait. studies show 60% of kids are throwing them out. i looked at new jersey school systems and found when you have a private intermediary, sometimes it's jazzed up more, sometimes got a private chef, fried rice, everything looking better. maybe they're willing to eat more. now that it's on the plate, got to get kids to eat it. seems to be improvement and increase increase. >> 50% of calories are coming at the time they're in school time. changing hot dog the to turkey,

hot dog to less at, more lean and adding fruits and vegetables is great news. our federal money is going to the right place. the childhood obesity and diabetes is on the rise. it has tripled over the last decade or so. we're not quite there yet. what happens is, after school, if you're not going to continue the same discipline. if they go home and take that soda, ice cream and fatty food, you basically make this feel fail. i think parents play a huge role. if you have a lot of pizza at home, children are going to have that. set a good example. children will follow. >> i agree. what's in the icebox? in terms of school, you may have a salad bar in 30% of schools but how many kids go by it? how many go for the french

fries? >> if you mix it up a little, are they more likely to choose the right things? >> they're not moving as we were. we played basketball, sports, et cetera. now they're hooked on computers, iphones et cetera. we need to get hem moving, educate better, high quality food. >> if you have pizza and french fries on a plate, and you throw in cauliflower, they're not going to eat that. every part should be healthier. if you've got french fries, they're going to eat that. we've got to get to the point someone is engineering this. >> it has to be inviting. >> michelle obama lunch program was a lot of start. it's a lot of money if it doesn't have impact. private solutions help to make it work. >> it's one step forward. >> i like mystery meat.
