chief of robotic surgery. >> and dr. mark seagul professor of medicine at nyu's medical center. also author of the "unlocking the secret code of sickness and health." >> good to see you. >> very good. >> so may is national fitness and sports month. and coincidentally, there's a new study that shows that regular exercise can lower the risk to some cancer by as much as 20%. which is nothing to sneeze at. what's the best way to get into shape? especially if you're in your later years? so i was really stunned to learn that exercise can have an impact on cancers. >> greg, first of all, i want to say that i had done a report a couple weeks ago about how sloan memorial is looking a the cancer patients, exercising them, finding their recurrence rates are down, they are doing better overall. an emotional component, a

physical component. here we are talking about ca cancers that haven't developed yet. we know that colon, breast and uterine cancer are decreased with exercise. but this looked at over a million people in 12 studies in major journal of internal medicine. you have a marked decrease in esophageal cancer, kidney cancer, liver cancer and leukemia. many other cancers they hadn't even looked at. i think the reason, and david will talk more about this, i think it has to do with the inflammation we are always talking about on this show. when you pump up your blood you get rid of waste products, insulin, inflammation, excess estrogen, which is why you don't have as much uterine cancer. >> but you mentioned inflammation. how much exercise are we talking about? i point out inflammation because a lot of elderly people are dealing with inflammation of the

knees and veins and stuff. they will say, what am i supposed to be doing. what's good for me? >> i think it is interesting to learn from this study that this doesn't apply to everybody out there. you still individualize the care. if someone has arthritis or suffer from back pain, we don't want them out there everyday for half an hour. they are talking about 150 minutes per week. so figure about half an hour a day would be excellent for this. it is a great study. at the same time, a lot of flaws because it was a self-reported by the patients as to how much they exercise or what they did. we learn a lot from this. the question is, how do they exercise? we know it can reduce diabetes and reduce obesity. how did it really reduce cancer? two things. one is on the cellular level. basically your immune system can get boosted. there is a lot of natural killer cells. your body, when you have some sort of a foreign cancer or flu that comes in, they go up and start defending it.

natural killer cells, t cells, the result of exercise, can go after the cancer cells. at the same time when you lose weight, especially among women, body fat, your estrogen level will go down. a great thing for breast cancer and endomy treeal level. and growth factors are a huge problem when you're really obese. by exercise, you reduce those hormones and perhaps reduce cancer. >> what's the take away, dr. seagull? >> i think everyone should exercise more. and to david's point, look, some people can only walk. but people say you're walking so rapidly, doc. you know why? i get in the habit of walking fast because that's more of an exercise. people wheelchair bound or exercises, they can do upper body exercises. i think bottom line and another thing i liked is it got rid of the idea that smoking or alcohol or diet played a role. we know those things play a

role. so looking at exercise alone without smoking or alcohol. i with say it keeps tipping -- and david's point they are self reported isn't the detraction but we are moving in a good direction. exercise good for your heart. we knew that. now seems to decrease cancer. >> especially in my field of cancer, exercise has to be parallel to what we do. now studies coming from australia where people get chemotherapy in the morning. right after chemo they go to the gym and work out. >> fascinating. >> we are understanding there are things in the muscle that as you exercise, at a cellular level, go up and can defeat cancer. so exercise before getting cancer, while you get cancer, and certainly now we have studies to show that it reduces recurrence h is important. so what is the take-home message for a lot of people? it's never too late. even in your 50s and 60s, can you catch up with some of this. >> and i was reading in the

study, even if you're obese, a little bit of exercise will go a long way to preventing some cancers. >> i think that group and we need further study on this. we look a lot at intense exercise. but that group that's obese has all of the inflammatory markers in the world. those are the group that sloan is looking at specifically. people already have cancer and as david said, they get their chemotherapy in the morning and their recurrence rate and spread of cancer goes down. this prevents cancer. obesity, especially if you can get rid of the excess belly fat, you will decrease the amount of inflammation -- >> what is interesting that mark is saying, sorry to interrupt, but in the prevention world, a great study that came out of the journal of oncology, that three things, if you just get rid of smoking, or alcohol, and add exercise, can you reduce the risk of cancer across the board by 40%. that's a big deal. >> and you still have

environmental factors. pollution, chemicals. >> a hundred percent. but exercise, smoking and alcohol, that can change the whole world and pay attention to >> so whoever wants to answer this, some people, as dr. seagull mentioned, the elliptical, some of that is intimidating. how can i smart small? >> i have two points about this. >> are you using yours? >> here are my two points. >> it's for sure. accessory. >> one point is, you don't have -- just spend less time on the couch. not only time you are intimidated by the elliptical, less time on the couch, more time getting up. standing, moving around, walking around. second point is, when you do go to the gym, bring something to distract you. like a book. i'm watching billions now. i bring it to the gym. i won't allow myself to watch it unless it is in the gym. so pave lonian conditioning. >> that's what i do, binge

watching. watch "breaking bad" or something. >> i watch hgtv on the treadmill. >> really? you can work on the house while you are exercise. >> i can't, because i'm here. you can, but i can't. this is not enough. >> a good way to push you. >> yes. okay, coming up, we will talk about this, fda approving a ground-breaking new treatment for early stage prostate cancer patients. but we will ask the doctors if it is safe. stick around. sunday housecall continues. a heart attack doesn't care if you run everyday, or if you're young or old. no matter who you are a heart attack can happen without warning. if you've had a heart attack, a bayer aspirin regimen can help prevent another one. be sure to talk to your doctor before you begin an aspirin regimen. bayer aspirin. here's the plan. you're a financial company that cares, but your logo is old and a little pointy. so you evolve. you simplify. you haven't changed. you still help people live their best lives.

so the fda approving a no one surgical noninvasive procedure offering hope for early stage prostate cancer patients. but how does it stack up when

other proven techniques are in place? so i ask, first of all, what is it, how does it work and who should get this procedure? >> the news broke out about two months ago. something called high intense focal ultra sound. what this is, and for selected patients, we lower prostate cancer and in small prostate this can play a role. there is a trance ducer in the rectum and with a general anesthesia, you use high focused ultra sound energy and can you burn the cancer cells. so if you select your patients, this actually could work well. there is a lot of data coming from europe. they've been doing this for many years. this just came out in u.s. and just approved. and the discussion with a patient is that it works well if you select your patient -- >> low risk, what does that mean? >> that's the very good question. when a patient cups to us, they may have a lower prostate cancer, or aggressive.

we call that the score. how many cores or how many areas of the prostate does have cancer? so the standard of care is removal of the prostate because it gives a very accurate staging. a week after i can look at the patient and say this is how much cancer you had, how far it's gone. six weeks later undetectible and zero. so this patients that don't want surgery. and this could play a role. >> as you know, dr. samadi, not everyone starts out seeing an expert like you. they go to their general practitioner, like dr. seagull, so at what point do you say to that patient, you have to go see dr. samadi? >> the issue is that the playing field is changing. because of robotic prostate surgery in the right hands i'm able to offer surgery to people that have more, what we call, more than ever before.

they are older, diabetes, heart disease. >> can you offer robotic surgery? >> no. there's people i wouldn't have operated on before. and i would have been looking for some other treatment that i can now say in the right hands, surgery may still be a first option because you can do it minimally invasively, be out the next day. you can operate on sicker people now mp. having said that, there are still people you wouldn't operate on and those people you might look for other choices. interesting thing about this, dr. samadi made a good point here, obviously he is the expert, you don't want to offer this to someone with advanced cancer. recurrence rate are 28%. those people probably shouldn't have td in the first place. it has side effects. you want to figure out the right treatment for each patient. there is 200,000 new cases a year and 25,000 men still die of prostate cancer every year.

we don't have all of the jeannetgeneti genetics figured out yet. if it is potential to kill you, get it out. >> and diagnostically you can't always see the little areas of cancer in the prostate unless you take the prostate out. >> that's right. the center of excellence we have in new york and many other centers, we are using mris, fusion biopsies, which is much better than the ultra sound, old-fashioned way of doing biopsy. but you're right, you still don't know how much cancer someone has. can you only treat about 10 grams per hour. if you have a large prostate, it could cost longer. >> i'm going to cut you off. probably a stupid question. >> never. >> so what is the prostate? >> the gland between the blatter and urethra and responsible for the semen that goes through it. a male organ that kind of the disease is very similar it breast cancer but for sexual function and the surrounding nerves around it. once you remove it, an expert

surgeon that is qualified, sexual function after surgery is good. for a lot of viewers, there are a lot of questions about this. if you are newly diagnosed, good to prostatecancer911.com. you can send your information and we give you free consultation to help you. it is getting very confusing now. >> stick around. elder care coming up on our agenda. a growing problem for millions of americans in the so-called sandwich information. important information from our doctors when "sunday housecall" continues in a moment. before i had the shooting, burning of diabetic nerve pain, these feet were the first in my family to graduate from college and trained as a nurse. but i couldn't bear my diabetic nerve pain any longer. so i talked to my doctor

welcome back now for "should i worry," our weekly segment about everything that worries us. our viewer is asking, i'm a 56-year-old woman. i'm increasingly concerned about my elderly parents. they're in their 80s, living on their own. they're becoming more and more frail. how do i broach the delicate topic of elder care with them. >> dr. samadi calls that the sandwich generation, i'm in it, i must say. because i'm a baby boomer with elderly parents. the first thing i would caution you is get checked up. may be doing great, but one fall, 250,000 hip fractures a

year in the united states. you may suddenly find yourself on a sliding pond going into an intermediate facility and then a nursing home. get your eyes checked, what medications are you on? as you pointed out before we came on here, greg, check your long-term health insurance. do you have coverage for this kind of thing? >> excuse me, there are people out there, this woman is 56 years old. her parents are getting older. she sees them becoming more frail. she wants to talk to them about this. this is a big problem for everybody. the parents want to maintain their independence. what do you say to the parents? >> that's a great question because most parents -- most people in this position find their parents are very resist ant and prideful and don't want to admit their body is failing. you have to get a physician in the loop on this and you have to go slowly. one thing at a time. i think they've got to know about the risk of hip fractures and the risk of losing their vision and medications. are they on too much? maybe that step down from the front of their house is one they

can't manage anymore. and then you have to involve lawyers and say, well, do i qualify for medicaid, which will provide long-term care? would i ever go into a nursing home or wouldn't i? if i wouldn't, how can we get aides into the house with help with cooking, bathing, cleaning. you have to do this. the more stubborn, the more -- >> multiple family members. >> dr. samadi? >> it's a serious issue as we are facing -- as older population are getting older and also the diseases are getting more complex, which is good. we always want to prolong life. now we have to deal with the complexity, which is as physicians we're not -- our health care system wasn't prepared for this. the sandwich generation, not only do they have to take care of their spouses, have you to take care of their children and father. tremendous stress, financial issues. i think it starts in the kitchen. i think it starts with the honest conversation, which we all want to avoid because we're talking about someone's end of life. you have to find -- how do they want to be taken care of? do they want to be in a nursing

home? do they want to be at home? do they like to have -- how much money is in their account and who has power of attorney? >> also checking into medicaid and medicare. not everybody has money. let's be honest. >> also, if you go to the hospital, would you want to have intubation, do not resuscitate status? that discussion starts very gently. that's how you take it from there. >> we have to leave it at that. we're out of time. >> one quick thing up. said end of life. let's call it the fourth chapter. that's how my mom -- she talks about it as the fourth chapter. >> it's true. >> so it's more gentle and accepting. so when you come to the hospital, we as doctors don't have to make that decision. >> look for practitioners who are sensitive and compassionate and treat elderly people with respect. >> for the family members to do it among themselves and not pass it onto the doctors. >> i want to get to the next su subject because it's all about deodorant. >> is it really safe? we'll ask the doctors coming up

next. >> not fair right there. with my moderate to severe ulcerative colitis, the possibility of a flare was almost always on my mind. thinking about what to where to go... and how to deal with my uc. to me, that was normal. until i talked to my doctor. she told me that humira helps people like me get uc under control and keep it under control when certain medications haven't worked well enough. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where

certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. raise your expectations. ask your gastroenterologist about humira. with humira, control is possible.

you have to feel healthy... on the outside ...at your core. trubiotics a probiotic from one a day naturally helps support both your digestive and immune health by combining... ... two types of good bacteria. trubiotics. be true to your health. welcome back. a reebt study raising serious health concerns about deodorants and antiperspirants. what's your take?

>> these deodorants have aluminum-based salts. people say you may get kidney disease. other people talk about thalates which can affect your endocrine. no study i find shows deodorant is a danger to your life. >> i was reading the material before the segment, dr. seigel. it struck me as an incredibly small and short study that reached this conclusion, using a deodorant is bad for you. >> it's only 17 people and it's out of north carolina. it's very short. the only thing i would say about it because we like to learn a little from each segment. i would say this, it's a reminder that under your arm are living bacteria. and the bacteria that are supposed to be there are called corny bacteria. they did find people that stopped deodorant and antiperspirant grow more staph. that's that super bug we talked

about earlier in the week. can you grow more staph if you stop it. i think you should continue what you do regularly. the people around you will appreciate it. if you don't precipitously stop using deodorant. >> wash and use soap. >> use antibacterial soap. that helps. >> i'm also glad dr. seigel uses a deodorant. >> so does dr. samadi. >> last week i asked if using a self-tanning cream is safe. i've been using it for a long time. >> i've been using it for years, a decade. it is safe. there's really nothing wrong because it's a dead layer. the outer layer of your body there's a lot of talk about these sprays that if they can cause copd. if you go there once and cover your eyes or nose. it also protects you against sun burn. >> it's getting rid of dead

skin. >> that's it for us. >> that's on my list, get a spray tan. >> have a great week, everybody. afghanistan says a u.s. drone strike can killed the taliban top leader. we'll take a look at what his reported death could mean for the war against terror. donald trump and hillary clinton are neck and neck. now sparring over guns in america. our political panel and foxes news digital editor chris stirewalt is here to break it down. meanwhile, bernie sanders ratchets up the tension with debbie wasserman schultz. he accuses her of playing favorites and not listening to the millions of his supporters. we're live on the campaign trail.
