what happened after that? >> sefrbl yecertainly years ago slight rise in psa from screening, and then i had more testing and had a slight rise in my psa, and the yourologist wand to do another biopacy, and i got extremely sick, even though i had antibiotics, i got a severe bacterial invection. my blood pressure went low, and i was hospitalized for four days in houston. >> you're okay now? that's all resolved? >> i'm fine. i had a heart rhythm problem afterwards as well, but now everything is fine. i don't have proskatate cancer. >> dr. miller, you hear a story like that, there are lots of different cases, but what do you think as a your alurologist whe hear something like this? he got harmed from going to the biopsy, the heart problem. how big a concern is that? >> i'm very concerned. i sympathize with dr. stark's position, his perspective on it, and i'm happy he's fully recovered and doesn't have prostate cancer, but that's a complication of the biopsy. what the task force has put forward is that would be a result, these types of complications are a result of the psa blood testing which is a complication of the biopsy. >> what do you tell your patients at the beginning of the process. someone says, i want to get a psa test. how do you talk them through? >> the first thing i tell them is what it's for, to screen for prostate cancer. it isn't to diagnose prostate cancer. the psa blood test can vary depending on the patient's situation, old, young, what their risk factors are for proskate cancer will be one factor in terms of my recommending a biopsy subsequently. >> doctor, your begz on this, you have written about this and talked about it quite a bit, and the american cancer society supports the new guidelines. what do you think the role of psa tests are? it sounds like people want to abolish it where. >> we need to move screening into the patient/physician relationship where physicians look at the patients and say these are the known harms, the benefits, there are a lot of harms but there may be benefits. do you want to get screened? and let the patient decide. >> look, i'm a doctor, and i would have a hard time answering that question. how is sapatient supposed to make thatdition? >> the most important thing is there's so much you could get a prostate screen without plaining to people that there are harms out there. >> what would you say to them? let's say i'm getting a test in your office. i know you're not a urologist. what would you tell me? >> i do practice general internal medicine. i think there is a point in time where the patient can legitimately say, doc, i can't make a decision. can you help mero make a decision for me. i think the doc should weigh the patient's concerns, weigh the patient's risk factors, also inform the patient that we don't rhey have good studies to show this saves lives. >> i disagree. there are several studies that say -- there's been a 40% reduction since the advent of psa. >> i heard you say, look, if you have symptoms, you should get te tested. what are symptoms? >> any urinary problemser it's reasonable to do the test there. >> most people develop that. >> it may be reasonable to to the tests. >> i don't mean to keep interrupting you. if you say the symptoms and most men are developing them, aren't you just testing them late? >> not necessarily. there are studies that say that's not the case. >> i bring it up because again, the conversations men have, they say i'm going to develop the symptoms which would lead to psa testing. you're saying wait until i'm more advanced in age and that could potentially be letting cancer run amuck. how does it effect your practice? >> may i respond to the symptom question? i disagree, i think patients that have symptoms need to be evaluated for many reasons, including a psa test, but number one, prostate cancer often is not curable once you have symptoms from the prostate cancer. >> keep in mind, all of us agee, i think you'll agree with this, men who are over the age of 50 especially should know the known harms associated with psa screening and treatment. it's really not the screen. it's the treatment associated with the screen that causes the harms. along with the potential benefits. >> dr. stark, you've been listening to this conversation. look, would you do it again? given all that you know now and that you have heard? >> i teach residents students, and when a person without significant risk factors is screened with any kind of test, a positive result is much more likely to be a false positive, and if that false positive leads to an invasive treatment or procedure being done, it can lead to consequences. unfortunately in my case, those consequences occurred. >> i'm glad you're doing well. i hope we tried to make this a little clearer for people. it's confusing. but it's fun to dive into these issues every now and then. thanks for joining us. coming up, what do do when a child's school is making him or her sick. we'll explain. grill master brett gallaway. he's serving his guests walmart choice premium steak. but they don't know it yet. they will. it's a steakover! the steak is excellent. very tender... melts in your mouth... so delicious... tonight you're eating walmart steak. what?

one of the residual effects to the water would be mold. certainly. >> drew miles is acting superintendent of redding schools. he's seen the video and he says there's no money to replace the roof. >> buildings continue to deteriorate, and we only have a small amount of dollars to spread to do just the minimal things like new roofing. >> there are some people who would say this would never happen in my school. >> lily of the national education association which is the largest teacher's union agreed to meet me in redding, pennsylvania. >> how big of a problem do you think indoor air quality is to a student's health. >> >> right now, the last estimates said about a third of our school, about a third of our schools have some kind of problem that causes respiratory problems in children. >> that's remarkable. >> it's horrific. it's horrific. >> would you send your kid to the school? >> to this school inwould i send my child to this school? for the quality of education that i believe that these teachers can provide and the principal will demand, yes. from a facility's standpoint, if i had another option, i would exercise it. >> you're the superintendent. people are going to be surprised because i mean, you're the guy who they're going to say, look, make it the school you want to send your own kid to. you can't do that. >> i can't with the financial means that i have now. >> i will tell you, the acting superintendent you saw was fired this spring after the story first aired on cnn. just this month, the school board said they're laying off more than 10% of the teachers in redding. no mention of repairs to the school. if you want to look for signs of trouble in your child's school, poor air quality in particular, one red flag is mold as you saw there. you might see it specifically staining the ceiling. also look for thick dust on the lockers and on the floor, and cars and buses idling inside. they can get in through vents and doors. if you see these types of thi things, sound the alarm. after the break, we'll take on flesh eating bacteria. a party?
