interesting one, there's a balance between the immune system and the cancer cells. and so that's why our immune system is not going after our own cells. what happens, jamie, if your immune system goes after your normal cells. not a good thing. type 1 diabetes. multiple sclerosis. regular cells that control the immune system. wait a second. this is a good cell. don't go after it. h is a cancer cell. those are t regulatory cells. what this dr. hancock has found is by reducing some of that power of these t regulatory cells now our immune system is going to get stronger and go after the cancer cells. >> do you have to have cancer before this study applies? >> yes. this is actually a study that was done in mice. it's not in human yet. it's not on clinical trial. but they have shown that by reducing the power of the t regulatory cells, they can go after lung cancer. >> are you born with cancer cells? >> you're not born with them. you actually -- people don't

know this. you can develop them very quickly and get rid of them with your immune system and never develop an actual clinical cancer. we're always getting rid of tumor cells all the time. as david is saying, if we could manage to rev up the immune system, because these t regulatory cells down regulate the immune system, if we could rev it up and destroy the cancer as it's developing as has occurred in these mice without causing autoimmune diseases where immune system cells attack our own cells, that's what we want to avoid. we don't want to rev up the immune system and have it attack our own body. in this study it didn't attack the mice's body. that's good. >> how should folks at home practice this? >> here's what people at home really should understand. cancer is misperceived by our bodies as not being foreign. we don't see it as an invader. science is now trying to figure out a way to get us to see it as an invader. so we make antibodies to it. those are called monoclonal

antibodies. we get a virus. we target the virus to the cancer cells. attack those cancer cells. make vaccines to the cancer cells as david was saying is going on in urology. anything to target the cancer cell as foreign. and get rid of it. in this case, these regulatory cells cause the immune system to rev up, go after the cancer and leave the body alone. >> wow. >> talk to your doctor about it if there's something that you can do. >> absolutely amazing. >> one of the things you just mentioned is, how do you boost your immune system? that's what we talk about on this show every week. which is get sleep. stop smoking. exercise. that's how you boost your immune system. that's an easy way for people out there. >> it's summertime. do check for ticks in the tall grass, golf course. examine if they're on you. a few years ago everybody was doing it. now there's alarming news from the cdc that says lyme disease, the rate is ten times higher, ten, than previously thought. dr. siegel, a few years ago you would go look all over yourself to see if you had one of those

little buggers. people forget about it. >> this isn't news to practicing doctors who have been treating lyme disease in this area. the cdc gets about 30,000 cases reported every year. the real number 300,000 or more. mid-atlantic states, northeast and upper midwest like minnesota, wisconsin, michigan. those are the most. somebody e-mailed me this week and said don't forget california because there's some areas there. anywhere in the country you can get it. these are the main states. what it is, it's not just deer you have to worry about. although deer is main part of the problem here. deer is going crazy. there's no natural predators against deer anymore. no wolves around. there's also rodents. rodents actually harbor the lyme disease. then the deer ticks pick it up and then they transmit it to you. it takes about one out of -- of every tick bite you get, it takes about 100 to actually tran trance mitt lyme disease.

they have to be on your body about two to three days, having bit you, two to three days to transmit the disease. >> what should we look for? what are the symptoms? >> i was so ready for you. i knew that was coming. if you have any kind of flu symptoms between march and november, real flu symptoms, fever, fatigue, all of that, usually those are not the months that you get the flu. look for lyme disease. 60% of the time you're going to have a target lesion. it's a bull's eye rash. typical, it's round circle with one dot in the middle. it's a bull's eye. and that's a typical one. you don't have to have it. but 60% of the time you would have the rash. the way you diagnose it is by blood test. there are two blood tests. your doctors know how to do it. what i want people to know, you go for a test. the doctor says it's negative. there's also false negative. if you repeat it again, it may take some time for the blood to convert to positive. >> when should you get tested

the first time and when should you go back for a repeat? >> if the rash continues and symptoms continue go for a repeat. 10 days to 14 days of -- we may be overtreating you. it's better to overtreat it. if this goes chronic, lyme disease can lead to arthritis, to heart disease and many other problems. >> quickly, marc, you always hear if you have a lawn, you're okay. it's only the tall grass. is that true? i was in the lawn the other day, and they're like, don't worry about it. >> i have one of those houses. i'm busy spraying it all the time. i've got deer fencing. i am so worried about deer and deer ticks. by the way, so much agree with david's point. you cannot overtreat this. once you get lyme disease it can really be a big problem. >> inspection is the way to go. look for it. >> very tiny. >> pull out the whole. you need a piece. you may still have a problem. >> that's right. >> thank you, doctors. great information. especially this time of year. doctors are now saying the buildup of a certain metal in

your brain may contribute to alzheimer's disease. we don't want that either. we're going to tell you what it is and how you can avoid it. there's even more concern about metals, this time from lipstick? >> what? >> what some women, they say, could be absorbing into their bodies when they get the lipstick out. the doctors will explain what to do and whatnot to do when it comes to potential metals in lipstick. >> stay with us.

her busy saturday begins with back pain, when... hey pam, you should take advil. why? you can take four advil for all day relief. so i should give up my two aleve for more pills with advil? you're joking right? for my back pain, i want my aleve. i don't know if it's the same as the copper that's in pennies, but there's really disturbing new research that shows too much copper in your diet could contribute to your risk of alzheimer's disease. what are we talking about, dr. samadi? >> so copper is one of the metals that is absolutely essential to our existence. it's important for our connective tissues. it's important for red blood

cells. and it's absolutely important to our existence. now what they're saying is there's too much of copper can actually damage what we call blood brain barrier. our brain basically has a barrier, has a gate. too much copper can really break that down and you will have accumulation of what beta amyloid,the plaque in alzheimer's. this has come back and forth. we've had mixed data about this. but what i will tell you is that if you have -- if you're deficient in copper -- >> you can test for it. >> you can test for it. that's a good point. 24 hour urine test. you take your urine for 24 hours. take it to the doctor. they check the level. or you can get a blood test for it. that's the way you know whether you have too much copper or not. we get copper from food. we get it from nuts, chocolate, oyster. it's all over. fruits and vegetables. even all the healthy stuff we've told you you would get copper from that. but you just want to make sure you don't have too much of it. >> what does that copper look

like, marc? is it the same as what we see? >> it's in foods. you're not going to see it in foods. what happens in the brain is as david was saying, it gets into the blood vessels of the brain. it's not supposed to get into the brain itself. what's odd here is that copper is very useful for nerves. it helps us make our nerves work right and our muscles and our bones. it's essential. but the question is, should you be taking supplements with copper in it? this may be the first study to say, well, wait a minute. this was done in mice. it was out of rochester. it found that even small amounts of copper were starting to build up and get rid of the drain, basically. there's a protein that enables beta amyloid to get out of the brain. with copper around beta amyloid was building up, causing clumps. the exact same clumps you see with alzheimer's disease. there's some concern copper, and maybe other metals. this is not proof, by the way. just the beginning. >> you guys are great at warning us which studies we really can

keep an eye on and which ones are right now. >> this is to keep an eye on. this is not to tell people out there not to eat shellfish or meat. copper pipes, water goes through copper pipes. i might want to tell you to watch out if you're using an old well. in other words, you probably shouldn't have old copper pipes in your water system. because that gets a lot of copper into your water. copper is good for you. copper is part of food we really need to eat. this is just something that shows us. we're doing more and more studies on this beta amyloid to see what role this plays. >> i think senior citizens sh this. a lot of times anemia, a low blood count, or ost ost pro sis, some of the causes could be low cop copper. >> are they adding it to the food? >> it's there. you don't want to take more. >> thank you, doctors. >> all right, doctors. >> didn't know that one. she has unwittingly helped millions. including us, probably.

[ both laugh ] [ male announcer ] introducing progresso's new creamy alfredo soup. inspired by perfection.

back now with "sunday housecall." this is a fascinating case. medical ethics, when they collide with the rush of technology. listen to this. over 60 years ago a doctors remove a removed and saved one woman's cancer cells without her consent. today her cremes known as hela cells are considered over the most useful in the history of science. they've been yooused to help treat cancer, polio and parkinson's disease among others. for the first time now the woman's family has a say in how those cells are used. dr. siegel, tell us about h henrietta lax. what did she do and what did the doctors do that created these cells? >> she was a very poor woman. she developed cervical cancer with the hpv virus, sexually transm

transmitted. she died rapidly. in those days they used radon treatments. they used the cells. for the first time they grew outside the human body. so aggressive. first human clone in the history of science. they used them later for 74,000 papers with all the cures you mentioned. they used them in outer space, in vitro fertilization. in 2013 for the first time these cells have been genetically sequenced. these are the very first human cells to be genetically sequenced. that's enabling scientists to figure out how the hpv virus turned it into cancer. the family came along and said, wait a minute. these genetic sequences are published all over the internet. these are mine, too. i inherited them. they went to the nih to dr. frances collins in the nih and said, hey, we should have some say over what happens to our cells. let's hear from dr. collins, head of the nih and former head of the human genome project has to say about this. >> we have been deliberating for quite a few years about what's

the appropriate way to balance these two compelling principles. namely that individuals should have the opportunity to decide how their own biological specimens are going to be used and what privacy protections they need. that's one principle. the other is that science advances for public benefit most quickly if data is accessible. >> some people feel that our souls are in our cells. souls are in our cells. life of henrietta lax." some feel their souls are in their cells and they want to be consulted. they just want to be consulted. now they will determine where these cells go. they are not receiving economic reimbursement because of a case and it went before the supreme court. they are not going to be paid for the use of these cells but will get to decide. will it slow the wheels of science. >> will it inhibit research? >> what i have to add to this, and by the way it was a nice

job putting this together, but the informed consent we have before surgery or during a trial is 15 to 20 pages of consent form. i guarantee you 60 years ago there was not this informed consent form. that's part of the problem. i think there is morally and ethically, that's a conflict. i can tell you she has made a huge difference in the world of science. with the genetic see yensing we have -- sequencing we have today. with aids and hiv it is based on this. the cancer kind of treatment we have today is based on this. whether it is cervical cancer. unfortunately she died a year after her diagnosis at john hopkins. we used that information. and 70,000 plus articles later on is based on the fact we can grow these cells. >> is this what it looks like? >> it is the cells we can grow in a petri dish.

we look at the cells in the heart, muscle and liver and the cancer cells. all of the articles we talk about including the first with the immune system and the cancer cells, a lot has to do with the signs we got so many years that are piled on top of each other. >> now you have to get informed consent. we go to the doctor and there are like this many forms. >> this is a good i'm to talk to the patients. when you go for any treatment we will put it in front of you and explain what the procedure is about. you have to read the consent form and you have to know what is going on. >> how many are there like her? a lot of people are wondering, hey, i wonder if i helped develop some science. joy my point is there will be more and more like her. as we sequence more and more people's cells we say this is a cure for this and a potential cure for that. the family is very happy. they are extremely happy and thrilled -- and this is to

david's point. their grandmother's cells have been so useful in the history of science. they grew like mad. you were able to study how they turned to cancer and how other cells grow and how you stop them with a vaccine. it was related to the cancer cell and because of henrietta. >> nih gets credit for putting two members of the family now in the board and they have some say to this. this is a happy ending and a major dedication to the field of science. >> henrietta lax, a medical name in science and history. >> give her the recognition and her family as well for helping. >> and hats off to the nih as well. >> doctor, so interesting. ladies, listen up. i know a lot of you are e-mailing me during the show if something we use every day can be dangerous. we have new details about what is in your lipstick? it may not be so healthy. stick around. we will let you know whether or not you need to blot.

now you know we are looking out for everybody on everything because we want to know whether or not there is a danger in your lipstick. there is a brand-new study and it is raising even more concerns about what millions are putting on their lips

every day. doctor, you first. you are not. >> no, i am not the expert. >> but we are, the ladies out there. >> there was a study in 2011 that listed 400 companies of lipstick with some metals in it and it was dangerous. it is the same thing. it is a following of the same exact thing. they are finding out there are seven or eight metals that are concerned. cad me yum can cause heart disease, diabeteses and cancer. can you imagine? there is aluminum we use in lipstick that is a stabilizer so things don't melt. >> they have to? >> they have to do it or else the whole lipstick will fall apart, so it is a stabilizer. copper, remember the segment this morning? that causes alzheimers and that is there also. and then titanium chromium and chromium causes stomach tumors. that was big news. this is not to scare people. what we are finding out is people who are using and reapplying lipstick 10 to 15 times a day x you basically absorb this through the mucosa

and you can chew on them and it is absorbed to your system. what is safe? three to four times a day, using common sense and not reapplying too much. >> here, i hit my four times. save my life. >> if i put it on the ratings will go up. >> really, is it safe if you use it judiciously? >> i like the point david is making. the thing is, we need standards here. the fda says .1 parts per million is all the amount of lead they will allow in kids products and that makes sense, babies and pacifiers and everything. but for lipstick they are allowing at least one part per million. the lead that is in these lipsticks that were studied out of berkeley, this is a study out of berkeley come close to .4 parts per million. it is more than we would allow our kids to have. and to david's point, if you are lick your lips and reapplying lipstick 10,000 times a day, which you are not, jaime, we just want women to be aware of this.

>> what about men kissing those lips? >> i would never tell them to stop that. >> no, we don't want to stop that. >> if you are kissing all day, but it is the accumulation of the metals. >> so everyone should be careful. ask your doctor. i take that back. the fda should look at it if it is getting in your system. i hope they will study it as well. >> all right, doctors, good to see you. back to our top story, the fox news alert, the united nations is confirming they are dispatching chemical weapons experts to the site of alleged poison gas attacks in syria as the white house is saying now there is, quote, very little doubt that the uh sad regime was the one that used chemical weapons against its own people and u.s. warships are poised and ready in the region. we wish you a good morning. 24 is a brand-new hour of "america's news headquarters." i am jaime colby. >> i'm eric shawn.
