as our chief medical editor dr. nancy snyderman reports tonight, sooner or later just about all of us may be facing this choice. and by the way, if starting in a few days time you don't see me around here for a while this is the reason why. >> bone on bone here and here. >> reporter: it is an operation some 650,000 americans will have this year. nearly double the number from ten years ago. total knee replacement surgery is often the last resort for men and women, many of them babyboomers, who have pushed themselves to the point where the cartilage in the knee has worn down. resulting in bone on bone contact and often excruciating pain. brian was playing high school football when he was sidelined by a violent injury. that is him, number 89, offensive end. >> you are a rather private person and yet here we are talking about the impending operation, why? >> i took a helmet to the knee in high school. it reversed my knee. they don't recommend that. i have been in pain for 35 years. i loved playing a team sport, i loved every

our chief medical editor dr. nancy snyderman starts us off. >> reporter: when he was in office, president bush's medical team declared him to be in the superior fitness category. with low blood pressure and low cholesterol levels. >> i had my physical. and i'm feeling pretty good. >> reporter: even after leaving office, president bush has continued to maintain an active exercise regimen six times a week. >> it doesn't take much time to stay fit. 30 minutes, five days a week. >> reporter: during a routine physical, the 67-year-old was found to have a blockage in one of the arteries of his heart. though sources tell nbc news, he was not having symptoms. the findings prompted doctors at texas health presbyterian hospital to insert a stent. a stent is metal scaffolding, placed into an artery narrowed by cholesterol plaque. it restores blood flow and prevents a heart attack. nearly half a million stent procedures are done every year, and sometimes more than one stent can be placed at a time. twice as many men than women wil

nbc news chief medical editor dr. nancyakes time out to join us from new york. >> hey, andrea. >> take us through this. i think a lot of people are so used to seeing george bush 43 as so athletic out there on the mountain bike and so young, relatively young. it's quite surprising given how thin he is. >> it is a real reminder we sort of pay the piper for the life we lived previously and it's possibly that the cheeseburgers and steaks caught up with him. you know him as a vibrant hiker and runner and obviously he is in very good health but on a routine examination at the cooper clinic he was found to have an abnormality. we don't know what that was, whether they saw a change in the heart tracing or whether he really had pain or discomfort when he was undergoing a stress test. but either way his doctors suggested that he have a stent put in to one of the coronary arteries that sends blood to the heart muscle. there are about 600,000 of these done a year. he's now become sort of very typical with being sounds like it's all gon

our chief medical editor dr. nancy snyderman has our report. >> which knee are we going to operate on today? >> the bad one. >> the bad one. >> reporter: it's early morning at new york's hospital for special surgery. dr. windsor is finishing his safety checks before bringing 54-year-old thomas apple into the o.r. >> feeling good. feeling nervous. feeling excited. >> reporter: tom is having total knee replacement surgery. doctors expose the knee and attach a metal plate and plastic to the tibia or shin bone where the cartilage used to be. then they cement a metal covering around the femur creating a smooth surface separating the bones. the numbers for total knee replacements are up in men and women, topping more than 645,000 cases a year. that's double the number of wrist, ankle, shoulder and hip replacements combined. like thomas apple, brian williams also suffered a painful knee injury playing high school sports. >> did you have to be talked into the operation or were you ready? >> every surgeon always said to me, "yo

dr. nancy snyderman. >> reporter: for georgia clark, knowing which foods are truly gluten-free makes a serious difference for her daughter's health. >> it's not a choice. this is a lifestyle that they have to live now for health reasons. and so i'm choosing to buy products from those manufacturers. and i know other people probably are as well. but having the government put their stamp of approval on it, huge. >> reporter: both have celiac disease, an intestinal disorder in which eating gluten can cause pain, inflammation, and even malnutrition. gluten is found in any products containing wheat, barley and rye. but eating gluten-free has become a fad for millions who don't have the condition, and it's big business. a more than $4 billion industry and growing. you can see gluten-free food everywhere, from the supermarket to the ball fields, even on the menu in many restaurants. a recent survey estimated that one in five americans buys or consumes a gluten-free product. that's far more than the num

dr. nancy snyderman reports. >> 62-year-old patty sutton works the early morning shift at starbucks. this previously retired barista didn't go back to work for a paycheck. >> i'm there for health insurance. that's about the only reason. >> she wants to retire, but her insurance covers herself and her husband, scott, who is permanently disabled. they are too young for medicare and can't afford independent coverage that allows them to keep their current physicians. >> we have to stay with our doctors. they are specific to what he needs and specific to what i need. >> next year people looking to buy their own will have more options through the affordable care act's online market place. >> they can compare prices for plans and see the different plans available to them. >> a new study finds between 500 and 900,000 people like sutton can choose to stop working or retire early based on new options. experts caution there is more to consider than price. >> you want to see whether your physician, whether

dr. nancy snyderman is here. what do we know about this tonight? >> we know how he was admitted to m.d. anderson cancer center and he did undergo a procedure last night. that procedure is being described as a complicated biopsy. you can read from that that it's likely that there was a tumor or some type of tissue left behind from this mass that was biopsied. we do know that he had a restful night. there have not been any complications, which means he's expected to go home tomorrow. but these can be frustrating times for families because families want answers, and sometimes if there's a complicated biopsy, it means you just don't have enough tissue to really make a definitive diagnosis, so now it will be days or weeks until that diagnosis is made and i can guarantee you the doctors between m.d. anderson and his doctors in philadelphia will be talking and sharing information daily to try to figure out exactly what this is. perhaps this procedure he had will take away the risk of stroke that he's

dr. nancy thanks. >>> we're back in a moment with a father, a daughter and a dream. >>> we're seeing rare footage tonight of former president gerald ford calmly and carefully remembering the attempt on his life in september of 1975 in a park in sacramento. it's largely unseen footage from the trial of charles manson follower lynnette "squeaky" froome. ford remembers seeing froome pushing her way through the crowd. >> as i stopped, i saw a hand come through the crowd in the first row. and that was the only active gesture that i saw. but in the hand was a weapon. >> the gun, you'll recall, was never fired and ford was not hurt. froome was released from prison in 2009. >>> tomorrow marks the 50th anniversary of the march on washington and martin luther king's landmark "i have a dream" speech. dr. king's youngest daughter bernice was just 5 months old that day in 1963. we sat down with her recently at historic ebenezer baptist church in atlanta where her father was pastor. she talked about the spee

dr. nancys as well. so emily, basically everything we've been told about pregnancy is wrong. women can drink, take ambien? is that what you're saying? >> no. not all of it -- not smoke. so when i got pregnant, i found like at lot of women a lot of more choices, like can i have a cup of coffee. >> the answer is yes, right? >> but the recommendations were confusing. book said one thing, doctor said another thing, people on the internet said 50 different things and realized that actually all of these come from studies and data and that was something i was comfortable with from my job and ended up taking my job as an economist and like moving it to my pregnancy and that was the genesis. >> coffee is okay. >> some coffee is okay. >> alcohol? you can drink alcohol? >> in moderation. very important -- >> bottle of vodka. >> bin drinking heavy drinking -- >> how much wine can a pregnant woman watching "morning joe" drink before 8:00? >> you're going to get in trouble, i'm warning you. >> how much wine?

here's chief medical editor dr. nancy snyderman. >> reporter: in ft.orth texas, today, 4-year-old julian aguilera is getting his measles shot. a quick pinch to the arm and a lollipop later, he's all smiles. it's a relief to his mom too. >> you don't want your kids to get sick. >> reporter: measles is making a comeback, and the latest outbreak in north texas. of the 21 cases originating at this mega church, at least 16 of those were not fully vaccinated. which means two shots as a child and for most adults a booster. >> someone who actually had the disease in july, had come back from a country where measles is more common, ink baiting the disease, became sick here and other people got it. >> across the country there have been 161 cases of measles in 16 states so far this year. that's nearly triple the number in 2012. while nine out of the ten children old enough to receive vaccinations get them. a pediatrician is concerned about the growing number of families who are opting out for nonmedical reasons. >> it's more middle class, upper middle class, peopl

dr. nancy explain the latest medical advances. up next, chuck todd and andrea mitchell join the conversation from washington. but first, bill karins with a check on the forecast. bill? >> mika, three things today. we have the uncontrolled heat in the midwest, we have fires that continue to burn in the mountainous areas of the west and also some storms for detroit. get to that in a second. first, california. eight wildfires now burning uncontained in the state alone. you've passed idaho for the most active largest wildfires out there. of course that rim fire has about 3,000 men and women on it trying to fight that blaze. in the northeast it rained hard overnight. the rain is beginning to exit. only left over there in rhode island and towards southern portions of massachusetts including cape cod and go back towards the airports we're okay right now. so no major delays. that's good. we're watching those storms rolling down through detroit too and will head for pittsburgh and possibly washington, d

we're going to talk to dr. nancy about extreme diets and we're going to brush upon this one diet. >> and we're start to go take a look back at the week in entertainment, everything everything from kim kardashian and her war on social media to a big win to the "ducks dynasty" crew. >> and we're going to take you to a very special restaurant where that day, as we found so many spots, a number of ordinary spectators turned into heroes on that day to help the wounded. they are the definition of -- the last business to oil on boylston street. >> lester has the right idea. bike riding at 8:00 on a saturday morning when it's absolutely gorgeous outside. but some area where it's chilly, down to the plains and into the southeast where temperatures will be about 15 to 20 degrees below average. normal high in atlanta, 88 degrees and it's only going to hit about 71 degrees today. mostly because of the clouds and the showers and that moisture streaming in off the gulf of mexico. so another six to eight inches of rain is possible

so there's a huge difference. >> dr. nancy snyderman, why?u want to consider it, on implants that are made in the united states. and i have to say, medicine is the only field i can think of that as innovation progresses, prices go up. they don't come down. anything else you look at, telephones, coulmputers. either other commodity goes down except medicine. no one has tackleled this series of medical problems with regard to economics and cost/benefit ratio better than she has in her articles. i think it points out the weakness with the american medical system and sadly so. >> i guess the other question would be if someone's making a decision like this, maybe it's better quality here in the u.s. and that's why it costs more. >> well, studies have never shown that higher costs correlate to better quality in u.s. medicine. so i think -- talk to people like michael choppen, they had a great experience. and talk to our 800 commentators who also talked about their experience overseas. also, almost to a one, excellent care. >> she writes this in well

here is chief medical editor dr. nancy snyderman. >> reporter: when liz degalle met linda nelson taylor their first year in college, the two quickly became best friends. >> she was always a true friend and a lot of fun to be with. we were like sisters. and it was an instant friendship. >> reporter: that bond lasted more than 20 years until linda died of ovarian cancer at the age of 43. it is a disease notoriously difficult to diagnose at an early stage. so in linda's memory, liz joined a study at m.d. anderson cancer center following more than 4,000 low-risk, post-menopausal women over 11 years using a simple blood test called ca-120, a common marker for ovarian cancer. by giving this blood test yearly and routinely tracking the results, doctors could pick up early stages of the disease with almost 100% accuracy. >> it is only when you look at it over time that it starts to become much more effective at picking up early stage disease. >> reporter: based on those results, some women had ultrasounds to look for a cancerous m

nbc's chief medical editor, dr. nancy snyderman, is here with more on what you need to know about lyme disease. first, help us understand this big jump. >> i think for a lot of us, it wasn't that surprising, because for years, we have recognized that we probably underdiagnosed this and the cdc today said they are looking at new ways of trying to figure out how many cases are in this country and this does give credence and credibility to parents wtients, over the years, had symptoms and frankly, doctors haven't known,put that into any bucket or category. when doctors can't do that well, they don't diagnose well. >> we will talk about the symptoms. some mimic other illnesses but what are the they? >> the classic is a bull's eye rash, the central point with a bull's eye and that happen 2s 4 to 36 hours after a bite. and then, flu-like symptoms, fever, aches, pain, headache. then some times, joint aches and muscle aches and when it can be misdiagnosed as arthritis. the tick bite doesn't mean you're going to get lyme disease.

dr. krants and nancy spinner are most concerned that the science has few guidelines. including safeguards for patients' privacy. >> we live in a capitalistic society. often when something is technically feasible and fiscally feasible. it is offered and there are for-profit company who is are offering this testing to the individuals. so you can go out, yourself, and pay t money and get your genome sequenced. the problem now is the $1,000 genome, but it's the $1 million interpretation. because can you get the sequence, but understanding what it does takes hundreds of hours of manpower to interpret and understand. and we're not even that good at it. >> as for dr. krants and his wife nancy and their three children -- >> i have to say neither nancy or i or anyone in our family has had their genome sequenced yet. and not because we wouldn't be interested, but i don't think we really subscribe to the recreational sequencing of genomes. if there was a medical concern, i don't think we would hesitate. >> for kathleen, even though the news about liam was not good, just knowing
