. Scott Webb (Host): This is One-on-One with Regional One Health, your inside look at
how we're building healthier tomorrows for our patients and our community.
Join us as we get to know some of the individuals who help provide life-saving,
life-changing care for our community.
I'm Scott Webb, and today we're talking with Dr.
Chelsea Olson from Regional One Health Cancer Care.
Dr.
Olson is a surgical oncologist and one of our areas of focus is
treating patient's with melanoma.
She's here to discuss skin cancer prevention and what's known as
CTD NA research, which is leading to new and improved treatment and
monitoring options for patient's.
Scott Webb: It's nice to have you here today we're gonna talk melanoma,
research and prevention, and you are an expert, so it's great to have you here.
And I just wanna have you start by telling us like what you wish
patient's knew about melanoma.
Like what are the risk factors, causes, maybe care options.
Dr. Chelsea Olson:
of the things that we look for in terms of risk factors for patient's,
who develop melanoma, you know, some things that lead towards it are.
Specifically uv, exposure.
So any exposure to sunlight, previous sunburns, especially in
childhood, previous, tanning bed use, things like that are all risk
factors for developing a melanoma.
Scott Webb: Okay.
Yeah, and maybe we can get into some of the causes and care options as well.
I'm going on a Crouse soon, you know, and I'm already thinking about, the SPF as
high as I can get it, and clothing with UV protection, you know, all that stuff.
But maybe you could talk about some of the causes and care options.
Dr. Chelsea Olson:
you know, causes, cumulative sun exposure.
We want to limit that.
And the ways that we can prevent that are, having adequate sun protection.
So what I tell a lot of my patient's are to use Sun Protective clothing.
, Not a lot of people think about that when they think about preventing
melanoma, but if you, purchase clothing that's protective of your skin, there's
actually qualities in some of the fabrics these days that block out uv rays.
And so that's actually really nice for patient's.
And anybody who wants to prevent, prolonged sun exposure, that's
something that you don't have to necessarily reapply like a sunscreen.
Scott Webb: Hmm.
Dr. Chelsea Olson:
you know, you mentioned SPF.
Scott Webb: Yeah.
Dr. Chelsea Olson:
how effective is that and kind of what we recommend and, you're gonna use a
sunscreen, I, I typically recommend, somewhere between SPF 30 to 50.
Anything beyond 50 is kind of.
Just extra credit, if you wanna call it that.
What's really important about sunscreen is the application of sunscreen.
Making sure that you're putting on enough sunscreen And that you're
reapplying when, that runs out.
You wanna look at, the back of the bottle and reapply when it says to reapply it.
And usually that's every hour or two, that you're in the sun again,
with the protective clothing, we like to think about, providing as
much, protection to EARS and face and other parts of our bodies that
we may not necessarily think about.
For some patient's, I think a lot of times we don't think
about protection of our legs.
We may focus on application of sunscreen to our faces or to our shoulders or
backs, but our legs sometimes get exposed to sun and aren't very well protected.
We actually see a melanoma develop in women a lot on their legs more than men.
So something to think about.
Mm.
Scott Webb: Yeah, I, I've heard some of the stuff you said before.
You know, like those sunburns we get as kids sometimes that bill
comes due later, if you will.
I've been reading and learning about the UV protective clothing and reapplication,
and I definitely skimp on my legs.
So I'm, I'm taking some notes along with listeners.
I'm like, right, don't just do your arms and your face and do those
legs and, and maybe your feet and your toes and you know, all of that.
Right?
so then what can we do to do our part, if you will, to prevent skin cancer?
Is it just following your advice here today?
You know, like, and how effective are these steps in your experience?
Dr. Chelsea Olson:
Yeah.
So, we know that sunscreen And the Sun Protective clothing is very effective
in preventing sunburns, and that's basically what we want to try to avoid.
Now, I always tell people who come to me, you know, who have been diagnosed with
a melanoma, we can't change the past.
We can't change the sunburn that we got when we were.
You know, kids running around And in the sun and not really have much sunscreen on,
there's nothing we can do to change that, but we can prevent, , more accumulation of
that radiation, damage of that sun damage.
And so even though, you know, the damage is sort of done, you know.
So to say, there are things that we can do to prevent even more.
So, knowing that there's just a cumulative risk, as we get more sun exposure.
It's always good practice to take those protective measures.
. And as I kind of alluded to, you know, the, efficacy, the usefulness
of sunscreen, it really does have a lot to do with how we apply it.
But also SPF, so, you know, I, I don't typically recommend anything below an
SPF 30 and, again, don't really typically recommend anything above SPF 50.
But kind of right in between.
There is a good sweet spot.
And then, you know, also just the daily application of, of
sunscreen or a, sun protection.
I oftentimes recommend like a face cream for patient's that has some type of SPF
in it as a daily protection from the sun.
Scott Webb: Yeah, I use a moisturizer.
I'm not ashamed to admit that has a UV protection built-in.
And, and I feel, and I feel pretty good about that choice.
Dr. Chelsea Olson:
Yeah, that's a good choice for sure.
Yeah.
Scott Webb: So I know doctor, along with, treating patient's, you're active
in research, including CT DNA research.
So I wanna know what That is exactly.
And what are some of the latest developments.
Dr. Chelsea Olson:
So CT DNA is, a type of, marker in the blood that we can use to follow cancers.
And it's being used a lot in colon cancer and a lot of other types of cancer.
Actually, it is basically a marker that looks at DNA in the blood that's
kind of, spilling off of the cancer.
And we can pick up those little fragments of DNA in the blood and sort
of see if patient's are at-risk for having recurrence or, if cancer is
coming back or something like that.
We haven't started that research just yet, but it is something that we're
interested in, the group that I work with and, a lot of it is also related to.
Sort of the, genes expressed on each individual melanoma cell.
We do some research with that too, where we look at the proteins
that the melanomas are producing.
And as you can imagine, everybody's different.
Everybody's melanomas is a little bit different.
And so we can actually look at the DNA of each person's melanoma and.
Sort of come up with a risk factor for, you know, is this melanoma.
Very aggressive.
Is this something that we need to watch closer?
Is it something that we need to, you know, keep an eye on for a longer
period of time or with special scans?
Those are all kind of put together as part of our plan to help patient's
after their diagnosis of melanoma.
So ctdna is, is a tool that's being used in a lot of other cancers and I think it.
Could have an application in melanoma.
So it's definitely something that we're looking into.
Scott Webb: Yeah, 'cause I was gonna ask you once this gets, gets rolling
and gets cranked up, whatever the right expression is, but once, you
know, once the research begins, you know, how will patient's benefit.
From, do you suspect any, what's your suspicion or your crystal ball
telling you how they would benefit from CTD NA related to melanomas?
Dr. Chelsea Olson:
Gosh, I wish I had a crystal ball.
But you know,
Scott Webb: Not quite there yet.
Yeah.
Dr. Chelsea Olson:
the hope in general for these types of markers is really to help catch
cancers, earlier and to catch cancer.
If we diagnose somebody with, a melanoma And we cure them of their melanoma.
They're always at-risk for having another melanoma come back or
having a new melanoma, And so we're always looking for ways to.
Find those recurrences or to find new cancers faster.
Right now we have imaging That is very helpful in that.
But a lot of times that imaging can't find the very, very small,
recurrences or the very beginning.
And so we're always looking to kind of move that, start
line a little bit earlier.
I think that ctd, NA I think that a lot of these other tumor markers
are ways that we can try to do that.
Scott Webb: Yeah, it's really fascinating.
No one ever wants cancer ever, but in talking to experts like yourself,
doctor, like if, you have a melanoma or any kind of cancer like This is
an amazing time for, you know, uh, predicting risk, assessing risk treating
cancers, it's really remarkable the science And the medicine and all
that stuff that's out there, and I'm sure that's what draws you to it.
Dr. Chelsea Olson:
Absolutely.
Yeah.
And I am very fortunate And in that I have a lot of colleagues that are
also interested in this, but the information is changing monthly,
weekly, sometimes even daily, depending
Scott Webb: May have changed while we're on today.
Right.
You never know.
Yeah.
It's really amazing.
Well, it's been a pleasure having you on.
I wanna finish up and just give folks a sense like why it's important,
why you believe it's important for them to see someone like yourself.
'cause you specialize in this cancer type and you're involved in the research.
Why would it be good for them to come see you if they're worried,
if they know they're at higher risk, whatever it might be.
Dr. Chelsea Olson:
Oh yes, absolutely.
I'm happy to see anybody who's high-risk for melanoma.
We have basically a built-in genetics program that will give genetic
counseling and even genetic testing for patient's who may be at a higher risk
for melanoma because of their family history or maybe even personal history.
But you know, when I see patient's in clinic, I do full skin exams.
I.
Evaluate, you know, if they have a diagnosis of melanoma, give
them options for treatment And the next steps in the treatment and,
hopefully cure of their disease.
And, we also work with a multidisciplinary group, so.
I have a, a lot of other physicians that I work with, medical oncologists,
radiation oncologists, a whole group of us that get together for a
multidisciplinary tumor board to talk about, very high-risk patient's And
also treatments for each patient.
So, you know, I think we are very equipped to handle, , any type of.
Concern that comes to us regarding melanoma or anything like that.
And, a lot of good treatment options as well.
And then lastly, you know, after here, I do a lot of melanoma surveillance.
And so basically after our patient's had their surgery or had their treatment.
We watch out for any recurrence that can happen.
Again, we're doing full skin exams and, taking detailed history and
making sure there's no other symptoms.
Scott Webb: Yeah, it's all pretty remarkable and it's all the stuff
we all want to hear, of course, that it's, individualized, it's
personalized, it's multidisciplinary.
It's a team approach that you stay with patient's after they've been
hopefully cured through surveillance.
Like all the important stuff that's just so.
Popular and common And we all expected.
I'm glad that, regional One Health is delivering And that you're delivering.
So thank you so much.
