-- and what if he's going to does not sure you -- diagnose skin cancer at home with just your Smartphone.
Well all the latest apps might be able to do that -- find out joining us now is dermatologist doctor Doris Day.
That the -- -- coming -- about this is -- -- for those of us who have to go win.
The most were Swedish and go in and get our skin -- this kind of embarrassing.
It's quite intimate you could do that would that would and I -- Well in theory it sounds really good but sometimes when it sounds too good to be true it is and you have to be really careful and nobody wants to hear the diagnosis of cancer.
And melanoma it kills one person every hour in this country it's -- number one cancer in women to 25 to 29 years old.
And the number one cancer killer in women thirty to 35 years old.
This is not something that just happens to old people.
Everyone needs to get their skin checked.
And look for melanoma because found early it has the greater than 98% cure rate here's what's it isn't about the -- University of Pittsburgh Medical Center analyzed for these Smartphone apps they didn't identify which one was which.
But they found that one of them was highly affected.
98% of the time it about you -- rightly identified the cancerous malls right because.
That one took an image and send it to a dermatologist.
So we we're pretty good at finding melanoma although it is the one thing -- one of our biggest nightmares to miss the melanoma.
And we really have only certain criteria to diagnosed melanoma -- so these apps that are out there my concerns are.
That you pick a spot and say I'm worried about this spot and need their take a picture sent it to a dermatologist or some of them have algorithms the lowest one of the worst of the apps -- a less than 7% accuracy rate so you don't really know what you're -- you know and after picking the right exact thoughts that's the problem is that you point to a spot.
And then it's a spot next to it that's -- melanoma and now you have this false sense of security and shows what what these machines okay.
So this is -- -- it's -- vaccine new diagnostic tool that I have in the office and it's available across the country.
And this is actually has -- 90%.
Find rate from melanoma so this is something that once I determine that a spot looks suspicious if -- I know it's bad I know I have to remove it if I know it's fine it's fine I get a sense of Dayton middle Castelli -- -- and I I had a lot of balls from I have that kind of -- Let's look acts.
Let's look at this spot.
It has a little bit of an irregular border -- and it takes less than a minute to do this.
So what this does is it looks at ten wavelengths of light that I can't -- with it with my naked eye -- Glued to near -- and it looks it over -- fifty different parameters and then it gives me a score.
So it's the next agnostic tool that once -- -- -- -- -- you that looks suspicious -- about -- did this and it doesn't appear close.
So I'm mark the spots and then they can be looked that and you'll see on the camera.
On the screen exactly as it looks down to the -- down to two and a half millimeters.
It gets -- score up higher low and within that gives a grade up and that -- helps me.
Diagnose and determine whether or not something so that we see the pick that's not critic.
Now I can see it looking all the way down yes and it's thinking and it's processing so even if -- came -- -- I how long does it take normally less and less than a minute forty seconds okay so should we move on to the other device and then we'll come back and see with this on tells us this when it's about to tell you now.
So what happens is that once -- -- at it and analyzes that I can determine if it needs to be removed and if and how much of a mark and I need Muslims to launch our league right now why I feel fine -- says she -- -- -- -- -- tested -- -- this device -- see what -- -- -- -- Photo box so this box helps me look through the skin in it in a simpler way.
So -- and see how much sun damage you've had and what treatments you might need.
And usually we do it in the rumor can be darker and I can have a good view I spent my face and you stick your face and there's -- and it helps highlight.
The difference between normal skin and sun damaged skin and even sometimes -- -- -- and Bechtel must look at -- Really we haven't received three can we show what you saw in there.
It was ugly.
Thought there again wow that was inside.
My gosh -- looking a little that -- an -- Afghan salute the RNC is.
-- that -- might -- until a bit of bacteria and left over make up really.
And then it's hard to see there but you can see highlights -- damage in -- -- can -- that there were few spots like this -- looked brighter.
I'm here knows what I saw was there are a lot of areas where I can see you've had a lot of sun burns in the past it's when -- turn it's our network yeah and stopping it.
I don't celebrities all the baggage area -- Friday but that also means that you are more prone.
The skin cancers and you have to be watched closely if you see something new or changing it's good to show your dermatologist.
And when we look at melanoma we think of the ABC DPs.
There's no car.
People look for raised but often melanoma are flat OK so -- -- exactly -- -- -- what a load yes it over and answers low risk of cancer and that's the best yeah that's always comforting but.
It's also goes along with a dermatologist diagnostic impression right and the fact that this team that alone means that we can continue to watch it and what you would get is a report with the picture yup and the grade CU can continue to compare overtime in the looks differently ticket and very quickly -- shots of the tops knocked in one -- spot check that you think -- -- Well spot check is the best of all of them because it takes the picture and sends it to a dermatologist to look at.
But my concern again is that you look at that one spot but people often don't -- when patients come and they say a word about this spot and that's the spot I'm not worried about I'm worried about the -- spots and we have to -- also -- all of I -- one taken off my back a basal -- -- -- enhance student -- -- -- I -- thanks so much interested hey great to see him again at me and that's why thanks pleasure thanks for the good partners and.
