times and seen the enormous toll physical and mental. ptsd is leading to more hospitalizations than physical injuries. startling figures to share. also this week's medical mystery. something we do every night could be making us gain weight. i'll tell you about it. let's get started. doctors may have unlocked a big secret which would help patients with the deadliest form of brain cancer. i's called glioblastoma. about 10,000 new cases in the united states every year. it's the same type of cancer that took the life of senator ted kennedy. there's a new vaccine out there that nearly doubled the survival time. double. think about that. it's extra time. it's what the patient you are about to meet, every patient, really, is fighting for.

>> you volunteered to do a spinal tap today for us? >> yes. >> she's bracing for another painful procedure. she's got cancer. brain cancer. a killer tumor called glioblastoma. gbm. this is typically thought of as the worst type of tumor, why? >> because left untreated, the patient succumbs to it. >> survival is barely a year if left untreated. here at the brain tumor center, karen found hope, an experimental vaccine. there's a futuristic name, cdx 110. it uses the body's own immune system to attack tumor cells. it won't work on all tumor

patients, just the ones that make one particular protein. in those patients, it goes off like a smart bomb. now, she gets a shot, a painful one, every month. look at the results. we were able to pay her another visit, a full year later. remember, most patients don't live that long. >> it's been a year and a half. as long as the vaccine works, then i'll be getting monthly shots. when it doesn't work, then i'm in trouble. >> dr. john sampson helped develop it. >> what can we say about the vaccine now. in terms of educating people. >> we are careful not to overpromise what somebody can deliver. it's still an experimental stage. patients are living two to three times longer with the vaccine. >> the results made public in june were less dramatic. on average, compared to regular therapy, it nearly doubled

survival time, as much as six years in some cases with no signs of returning cancer. >> i want to take a second to show you how it works in the brain. you are looking at a glioblastoma in the brain. what's so interesting is in a certain percentage, they have a protein unique to this tumor. you can train the immune system like you see here and go in like a smart bomb and attack the cancer. you are training your body's own immune system to fight a tumor. we are seeing great results. the average survival, 14 months. with this treatment, closer to two years. it's almost double. 18 patients were studied. the results are so promising. some patients lived five and over six years. they are strong with no sign of returning cancer.

they are early studies, to be fair, but there's hope more studies will prove treatment is going to be more available. one of the cancers people talk about, breast cancer. there's new guidelines, they sparked controversy as you know. they sparked confusion. is it worth it to get a mammogram and at what age? i'll answer the viewer question in the ask the doctor segment. meet a man that inspires us all. he's teaching us the strength that comes from within when you really want to succeed. i'll explain that. [ female announcer ] imagine the possibilities

with stelara® for adults. stelara® helps control moderate or severe plaque psoriasis with 4 doses a year, after 2 starter doses. in a medical study, 7 out of 10 stelara® patients saw at least 75% clearer skin at 12 weeks. and 6 out of 10 patients had their plaque psoriasis rated as cleared or minimal at 12 weeks. stelara® may lower your ability to fight infections and increase your risk of infections. some serious infections, like tuberculosis, require hospitalization. before starting stelara®, your doctor should test for tuberculosis. stelara® may increase your risk of cancer. always tell your doctor if you have any sign of infection, or have had cancer. alert your doctor of new or worsening problems including headaches, seizures, confusion and vision problems. these may be signs of a rare, potentially fatal condition affecting the brain. tell your doctor if you or anyone in your house needs or has recently r. with 4 doses a year, after 2 starter doses it's stelara®.

thanks. i got the idea from general mills big g cereals. they put a white check on the top of every box to let people know that their cereals have healthy whole grain, and they're the right choice... (announcer) general mills makes getting whole grain an easy choice. just look for the white check. we are back with sgmd. it's breast cancer awareness month. we have lots of questions about breast cancer screening. a blogger says this, is it worth it to get a mammogram? we have lots of questions along these lines. it's a good question. it's a confusing issue. most agree getting a mammogram can find cancer at an earlierier. this is a screening tool with limitations. it's not perfect.

in about a small number of cases, a tumor can be missed. on the other hand, some things picked up can lead to a biopsy and can turn out not to be cancer and that can cause anxiety. a lot of groups agree, despite the limitations a mammogram is an effective screening tool and women's lives can be saved if the cancer is found early and treated early. there's been a lot of controversy over this and we have covered it about when a woman should start getting a mammogram. the acs and comprehensive cancer network recommend a woman get it annually beginning at age 40. that's the number you should tuck away. if you have a history of breast cancer, get screened earlier. again, the confusion. i don't want to overestimate or underestimate this, but there's been confusion in the past. there's no question a better screening test is necessary, but i want you to have the best information we have right now.

we have a new series that we are loving. it's called the human factor. we get to introduce you to remarkable people that i find inspiring. in learning their stories we learn remarkable things. this week, i'm going to introduce you to a fellow neurosurgeon and tell you about his path to medicine that is different than anybody you have ever met. this is dr. alfredo hinojosa. they call him dr. q. here taking out a life threatening brain tumor. quite an operating room. the scans are up. johns hopkins, one of the finest hospitals in the worlds. >> this is my room. they build this specifically for our service. >> at 42, dr. q is at the top of his game. life wasn't always like this.

in fact, it's been a long journey from his hometown in mexico. he started working at the age of 5 as his family's gas station. his family was poor and things got worse when the business collapsed. in 1987 he headed north to the border. >> there was one choice i knew i had to make. i jumped the fence. i climbed the fence between mexico and the united states at age 19. >> his first job? pulling weeds in california's central valley. >> i remember, i tell you, my hands, the hands that now do brain surgery, right around that time, they had scars everywhere from pulling weeds. they were bloody. >> this trailer was his home. he knew he could do better. he worked for the railroad. he got money to go to school. he got a scholarship from california berkeley. from there, he went to harvard

medical school. >> did you ever think, i don't belong here? >> many times. i think that's what has kept me on the top of my game. in medical school, i remember thinking, wow, look at my classmates. you have some that train at the best prep schools in the country, from the most distinguished families in the united states, from tradition of education, and there was me who barely had an education, but i was eager to learn. i had -- i always knew that i had something that others didn't have. that was that fire in my belly that keeps me going. there is my girl right there. >> the fire still burns today. he takes out brain tumors and does research he hopes will lead to better treatments. >> do you sit around, you and your wife, and pinch yourselves?

your wife has seen you go from being a migrant farm worker to here. >> we think about it. i feel blessed. when i walk out of the operating room and i give the patients the news that everything went well in surgery and they hug me, it's the most rewarding moment that i can think of. >> just an amazing doctor. an inspiring person and an amazing story. dr. q, thanks for sharing with us, if you are watching. war is taking its toll on our troops. i'm going to tell you about the struggle to keep them mentally healthy. that's next on sgmd. fiber one chewy bar. how'd you do that? do what? you made it taste like chocolate. it has 35% of your daily value of fiber. tasty fiber, that's a good one! ok, umm...read her mind.

america's longest running war has taken a severe toll on the physical and mental health of our troops. i spent a lot of time on the front lines in afghanistan and iraq. i have seen the devastating effects of the war. the one thing we have talked a lot about are the suicides when they come back. there's so much they are dealing with.

as the war progressed, the mental wounds are one of the things you cannot ignore at any level. if you take a look at the numbers, i think they are the most striking. pay attention to these. in 2009, more u.s. troops hospitalized for mental health issues than physical injuries. take a look at that. it should say a lot to anybody who looks at those numbers. it's worse for those serving multiple tours. if you are redeployed, the rate goes up. the numbers are making it increasingly clear that this is a problem. officials are taking notice. joining me is tom tarantino, an iraq veteran. thanks for joining us. >> thanks for having me, sanjay. people referred to it as the elephant in the room talking about mental health issues. i know for a long time, they thought about mental health

issues as a disorder as opposed to an injury. the thinking is starting to change now. the suicide rates, tom, are so disheartening they are creeping above civilian rates. why do you think the numbers continue to rise and do you think it's a problem that can be addressed? >> it can be addressed. it's a symptom of a force that's breaking. it's a force that's stressed to the point where things are starting to go wrong. i think we are starting to see that the top brass at the pentagon are understanding these issues. i believe they understand these issues. the problem is, it's not getting down to the sergeants, the lieutenants and captains on the line day-to-day with their troopers. if we can bring that type of awareness to the line leaders, they can get the troopers back into the fight. >> it's not filtering down, so

to speak, does it result in stigma or is it people don't want to bring up the issues because the people on the front lines aren't adequately addressing it? >> you mentioned the elephant in the room. stigma really is the elephant in the room if we want to talk about it. people are afraid to seek treatment. why? they might look weak to their buddies. we have to change the culture, not just in the military, but in society as a whole to look at post-traumatic stress and brain injury as injuries not disorders. i tell troopers if you got shot in the chest, you are not going to walk around with a bullet hole in the chest. you go to the doctor, get treated, heal and get back in the fight. we have to change that so people look at mental health injuries like that. >> the stigma is a concern, not only among troops, but among the civilian population as well. what does make that change?

how do you change that culture? i'm a doctor asking you this. i have seen it for 20 years. do you have ideas or have you seen anything that works? >> there are things that we can do within the military community. first of all, education, education, education. the army is starting to train mental health resiliency throughout the life cycle of education for sergeants and officers. they need to make that a regular part of your professional development as you progress through your career. i fought to get mandatory health screenings for everybody returning from iraq and afghanistan. we think the early and frequent screenings could save more lives than all the armored vehicles money can buy. here we are a year later and we can't get enough mental health professionals to meet the need. ft. hood, up to 4,000 mental

health visits in a month. most hospitals can't handle that. we have heard this referred to as an emergency situation, the idea of mental health injuries. i'm using the word injury specifically here. have you seen progress being made? >> yeah. i mean, the reality is we are in a better place today than two or three years ago. the defense center for excellence in brain injury and mental health did an excellent job of getting smart on the issue. these are issues the military frankly ignored for the last 50 years. we have the national intrepid center for the excellence. we have a physical place that is part recovery -- recovery lab and think tank on where we could do the big think on these issues and solve some of these problems not just for this generation but for the next generation and the generations after that. >> you know, you think about what it's going to look like 10,

15 years from now for people who did not receive adequate treatment. you and i are talking about this in 2010, but this is affecting people for a long time tcome. thanks for being a measured and important voice on this. and we're going to keep talking about it, as well. thanks for joining us. >> thank you, sanjay. appreciate it. >> and we'll be right back.
