dr. nancy snyderman is nbc's chief medical editor. she's here this morning. >> hey, david. >> so what kind of tumors are we talking about and how worrisome are they? >> they are the most common brain tumors. they are benign, but even if you have a benign tumor in the wrong spot it's bad news. and we know that the most common environmental cause of these is ionizing radiation. that's the kind of radiation you get in x-rays. so this really looked at people who got a lot of dental x-rays, so kind of bite wings where you put the little thing between your teeth and something called a panoramic view, where they do an external x-ray. and they found that people who had those bite wing x-rays were two times more likely to get menagenomas than people who had this kind of x-ray you're seeing now were almost three times more likely. >> and kids often get the bite wings, right, on an annual basis? >> yeah, that's right. you know, used to be that there was more radiation with each of these x-rays. and we've talked about it on this program that more

dr. nancy snyderman has the report. >> today's study looked at new cases of melanoma diagnosed in young patients over a 40-year period, and its authors say the results are alarming. the rate of melanoma, the deadliest form of skin cancer, was eight times higher among women 18 to 39 than it was in 1970. among men, four times higher. >> some people would consider melanoma, especially in young women, almost an epidemic. >> while the mayo clinic study didn't look at the reason, researchers point to one big culprit, indoor tanning which was introduced to the u.s. market in the late '70s. one recent study showed using tanning bez increases the risk for melanoma by 74%. >> i did not know what to say. >> jody duke said her pale coloring meant she couldn't get a tan in the sun, so as a teenager, she started going to tanning salons. >> it started off as once a week and then maybe twice a week and then eventually, it got to every day that i was tanning. >> and she believes she paid a price for it. at 19, she was diagnosed with malignant melanoma and underwent surgery and extensive follow-up treatments. the

dr. nancy snyderman. >> reporter: it's no surprise that americans are getting fatter, but a new study finds the obesity epidemic could be a lot worse than anyone thought. the new face of obesity could actually look more like this. this is barbara hemerly-golask. she's now at a healthy weight but a year ago, doctors determined she was obese. even though her body mass index or bmi, indicated she was normal. >> when i saw the results it was utterly shocking. >> reporter: bmi estimates a person's body fat based on height and weight alone. dr. eric braverman, who led the study, says the widely used method is overly simplistic and significantly underestimates the prevalence of obesity. >> bmi doesn't tell you how much fat you have. that is the predictor of heart disease, cancer, stroke, gallbladder, fertility problems, depression, anxiety, sleep disorder, et cetera. >> reporter: the study looked at 1,393 adults and found that 48% of women were misclassified as not obese based on bmi. for women, the bmi doesn't take into account the loss of muscle mass that comes with age. dr. braverman says a com

dr. nancy snyderman. >> health experts have been aware for some time that type two diabetes is on the riseor young people, but today's study also claims that children respond much less effectively than adults to all kinds of treatments. >> the take-home message is it's better to prevent diabetes in children and adolescents because it's very difficult to treat. of the nearly 700 children between the ages of 10 and 15 tracked in the study, patients taking a single diabetes drug failed to control their diabetes more than half of the time. the same drug plus changed in diet failed nearly as often. even the use of two medications failed for nearly 4 of 10 children. william legare is a 20-year-old from new york city who has been trying to control his type two diabetes since he was just 14 years old. >> i know that my health comes first, so i'm actually watching everything i eat. >> what's up. >> the key is a healthier lifestyle before one is overweight, before one has type two diabetes. >> today's study is frankly depressing, and although it helps some doctors figure out better approaches to hel

dr. nancy snyderman, is with us tonight from london, heathrow airport. nancy, good evening. >> good evening, brian. tomorrow, the runway behind me will come alive as 195,000 people board planes and leave heathrow. many of them carrying the threat of measles. over a decade ago, u.s. health officials believe measles would be eradicated. but today's report by the centers for disease control was sobering. not only are measles back in the country, but the members are growing. >> they're being reported as well as the threat of there being many outbreaks. it's still a real and present danger. >> the cdc report shows that in 2001 to 2010, an average of 60 measles cases and four outbreaks were reported. last year that number jumped to 222 cases and 17 outbreaks. measles is a highly contagious respiratory disease caused by a virus. the symptoms include fever, runny nose, cough, and a rash all over the body. the main culprit for the uptick, global travel. as the world gets smaller, the threat of contagious gets much larger. more than 90% of americans who caught the

dr. nancy snyderman. >> hi. >> you're very brave. so public, as always, trying to help other people. >> yes. >> so you gained what two-thirds of the weight that you had lost. >> right. >> after the pregnancies that you had. so what made you and the doctor decide, we've got to do this again, we've got to have weight loss surgery again? >> yeah, you know. i didn't know that that was an option for me. i was at the point where i did need intervention. i didn't see the scale move for two years, and medically, i mean, i'm 44 years old. i'll be 44 this month. it's almost 13 years after the first surgery, and i needed to take action. i needed to help myself again. and i'm not ashamed to talk about this in public. it seems there's been so much support over the years, and it's still interesting to people, because so many people relate. >> mm-hmm. nancy, 79%, according to a recent study, of patients who underwent gastric bypass surgery, reported some weight gain. so why -- >> well, some is okay. but when you compress a stomach, and sort of rero

dr. nancy snyderman is nbc's chief medical editor.morning to all of you. >> good morning. >> boy, we have a lot to talk about. let's start with the george zimmerman case. he's now been charged with second-degree murder in the shooting of trayvon martin. star, our lawyer, i'll start with you. do you think the prosecutor got the charge right? was it an overcharge? >> i think that prosecutors like to charge as high as they think that the evidence is that shows them right now. she obviously knows a lot more than the rest of us do. and i think one thing that was extremely impressive is she now focused america's attention on justice and due process. that this process for her was really about taking care of the victims, protecting them, but now it shifts to making sure justice is done. and i was extremely impressed with her. >> which leads me to the next point because i don't think there can be any denying that public pressure is part of the reason that we got to the point where a charge has been filed. but donny, i'll put it to you. do you

dr. nancy snyderman. before she took on the co-hosting role, she sat down with matt lauer and talked about the republican presidential race. he asked if she would like to see a shakeup in the race at the convention. >> you know, anything is still possible. there can still be a bit of a shakeup. but the numbers are what the numbers are. yeah, he does seem to be obviously the front-runner. and i've been of the mind-set that anybody but obama will be so much better for our country. >> sarah palin also left open the possibility that she would consider being part of the republican presidential ticket, should she be asked. >> in virginia, democratic lawmaker david england said he's not going to seek a fifth term. in his statement, england admitted he had been unfaithful to his wife. he represents alexandria and parts of fairfax county. >>> gas prices holding stetd i right now, but don't get used to it. more gas price hikes are just around the corner. in about two weeks, many refineries will undergo seasonal mai

dr. nancy snyderman, not too bad either, nbc's chief medical editor.d morning, professionals. >> she gets more joy out of crushing sarah palin than me. >> you're her favorite person to punch. you always will be. let's start with the o.j. simpson case. it's back. there is a new book that's stirring some controversy, as you might expect, the author contends that he's done his own investigation and points the finger at simpson's son, jason. star, i'll let you start on this. >> you know, i feel like every time i try to get out of this case, they pull me back in. i've been covering it now for almost 20 years. jason had an alibi at the time. and he's the old of the son. and believe me, the police did more investigation than anybody could ever imagine on whether or not jason would have had the time to have left his kitchen and get there and commit these murders. i just think it's the most fascinating trial because people still have their own theories of how it went down. >> which brings me to my point with donny. there's still a cottage industry around the o.

dr. nancy snyderman says will sneak up on you. >> it sort of looks like a cold.ny nose, fever. but all of a sudden that cough becomes a barking cough and then a real struggle to get air. >> reporter: for health officials it's all about vaccination and booster shots if needed. especially for those who come in contact with toddlers or infants, the most vulnerable victims. >> i had inadvertently given my newborn a potentially life threatening illness that was so easily prevented by just getting my booster shot which i was unaware i needed. >> not only does whooping cough vaccine work, it is safe and can save your child's life. >> again, the key is vaccination. experts say when 90% of those in high impact areas are vaccinated, the epidemic begins to recede. >>> now a police chase across two counties. >>> tonight at 5:00 the original video has 86 million views and counting. now there is a sequel to kony 2012. we'll tell you who's missing. >>> and the megamillions mystery. it takes another twist. even surveillance video from the 7-eleven can't reveal the winner. good e

dr. nancy snyderman is nbc's chief medical editor. >> hey, matt. >> how do you respond to someone who saysnd, at 16 or 17 years of age, isn't it too early for these kids to reach an option of last resort? >> well, that's just the problem. they've run out of all options. diet and exercise don't work, their hormone levels have changed so they're in a state of perpetual disease. and obesity, it's linked to heart disease and liver disease and their cancer rates go up, you're talking about young adults. who really only have surgery as an option. >> tom mentioned in his piece that the risks are the same for teens and adults who suffer from obesity. what about the risks of surgery? are they the same, as well? >> they are the same, except that once you stop absorbing nutrients and vitamins and minerals that happen from the surgery, and you're still growing, you have to really think about supplements. we talked to carnie wilson yesterday about the fact that she had gone through surgery before. and it didn't work well for her. the first time around. and now she's having a second run. and i think one
