Advocating for Those With Crohn’s DiseaseTomiyo Williams was immersed in Crohn’s disease life when her daughter, Skye, was diagnosed. Tomiyo decided she wanted to help others navigate the journey and took on the role of advocate to assist other families going through the same thing.263

TOMIYO WILLIAMS:

When my daughter was 14 years

old, she was originally

diagnosed

with ulcerative colitis,

and then ultimately she was

diagnosed with Crohn's disease.

To get a diagnosis like that

involving your child,

it hits you like a ton

of bricks.



SKYE WILLIAMS: I was used

to living my life normally,

as a normal teenager.

And then I was diagnosed.

It was really hard to go

through.



TOMIYO WILLIAMS: As time

progressed, her overall quality

of life just diminished at one

point.

That's when it hit me,

I needed to make a difference.

And I said, you know, I'm

interested in supporting parents

in any way that I can,

as well as supporting

the patients.



Her GI group, they reached out

and asked both my daughter and I

if we would consider joining

the Patient Advisory Council.

So we would go to the hospital

to meet with parents

and patients.

On a one-on-one basis,

I primarily worked with parents

that had children that were more

critically ill,

like my daughter.



The peer-to-peer communication

means so much.

It's a lot different

than talking to a physician

or talking to someone that may

not be going through it

firsthand.

We try to be extremely

transparent

and discuss how certain things

make us feel,

because that's what they're

looking for.



One of my big projects

was working with the Crohn's

and Colitis Foundation

to pass a bill that would reform

step therapy slash

fail-first therapy.

For instance, a doctor could

recommend a specific course

of treatment for a patient.

However, some insurance

companies require

that the patient would fail

a few medications first,

and you run the risk

of the patient becoming more

ill.

By reforming it, the patient

could automatically

go to that drug

the doctor originally

prescribed.



We ended up going to the state

capitol.

My daughter and I were

able to meet

with our local representatives.

In March of 2019, my daughter,

she was admitted.

And when they were bringing

her out of surgery,

someone from the Crohn's

and Colitis Foundation called me

and told me that the bill had

been passed.

SKYE WILLIAMS: It's been a fun

experience seeing all

the different ways that we can

advocate,

so I'm very grateful that I have

my mom, my best friend,

by my side

during a time that's so hard.



TOMIYO WILLIAMS: Because I

always felt that there was such

a need for support,

I created a blog.

The name of my blog

is The Rainbow In My Skye.

My daughter, no matter what she

went through, she always

remained positive, and it helped

me.

I try to connect

with the parents.

I try to share my stories.

Also, one of my most

recent projects

has been speaking at women's

health events.

You know, what it's like to be

a mom with a child that has

Crohn's disease, because being

a caregiver to a chronically

ill or disabled child,

like, it just-- it changes

everything.

I didn't even realize that there

were other parents that could

relate to me.

That's been a key factor, making

sure I'm building

that connection.



SKYE WILLIAMS: She used

something that was hard for both

of us

and turned it into something

helpful for other people that

are also going

through the same thing

that we went through.

It's very inspiring,

and I look up to her for it.



TOMIYO WILLIAMS: We've done

a lot of research, you know,

but again, when it comes

to the patient, it's not just

the research.

It's working

with the medical team.

It's so important that you find

a doctor where the lines

of communication are open,

and that if you've got

questions,

they're going to be

willing to answer, no matter

how many questions that you

have.

I can't express that in words,

how important that is.

If you have Crohn’s disease, you may need to get checked more often for early signs of colon cancer. But most people with Crohn's don’t get colon cancer, and there are things you can do to lower your risk.

The two keys are to keep your Crohn’s under good control and to keep up with your colon cancer tests. Ask your gastroenterologist how often you should get a colonoscopy. The general recommendation is that people who've had Crohn's disease for at least 8 years should get this test every 1-2 years.

Findings on this are mixed. Some studies have found that people with Crohn's aren't more likely than anyone else to develop cancer. But other research has reached the opposite conclusion, showing a substantially higher risk.

Inflammation is one of the ways the two conditions may be linked. Crohn's causes high levels of inflammation in the intestines. That inflammation, in turn, may make it more likely that abnormal cells that could become cancerous could develop in the GI tract.

How long you’ve had Crohn’s. Most experts agree that the danger goes up the longer you've had Crohn’s. One meta-analysis (in which researchers crunch data from several earlier studies) showed that about 3% of people who've been living with Crohn's for 10 years developed colon cancer. That number rose to about 8% for those who had Crohn's for 30 years.

In comparison, the odds of developing colon cancer at some point in your life -- what researchers call the average lifetime risk of colon cancer for the general population -- is about 4%.

Liver complication. People with inflammatory bowel disease (IBD), including Crohn's, almost certainly have an increased risk of colon cancer if they've developed an IBD liver complication called primary sclerosing cholangitis.

Colon cancer also seems to be more dangerous for people with Crohn's disease. One recently published study from Sweden found that people with Crohn's who get colon cancer are more likely than other colon cancer patients to die from it.

There are several ways to help protect yourself from colon cancer if you have Crohn’s disease.

Work closely with your gastroenterologist to manage your Crohn’s. You want it to be as well-controlled as possible. Seeing your doctor regularly and taking your medications as prescribed will help keep inflammation in your gut in check.

Keep up with your health screenings. Colon cancer is most treatable when it's caught early, and getting regular colonoscopies is the best way to do that. Doctors are often able to remove precancerous polyps during this procedure, which means that it's sometimes possible to stop this cancer before it even starts.

Getting regular colonoscopies may reduce your chances of getting colon cancer. A large study of nearly 7,000 people with IBD found that those who had a colonoscopy within the past 3 years were less likely to develop colorectal cancer. The same research found that frequent colonoscopies may save your life even if you do get cancer: People with IBD who had a colonoscopy within 6-36 months before being diagnosed with cancer were less likely to die from it.

Ask your gastroenterologist if you'd benefit from including chromoendoscopy in the procedure. This means that blue dye will be sprayed into your colon during the colonoscopy. The color helps your doctor spot flat, precancerous lesions that might otherwise be difficult to see.

Reduce other risks. Curb other risk factors as much as possible. For instance:

  • Be physically active.
  • Keep your weight in a healthy range.
  • Include lots of vegetables, whole grains, and fruit in your diet -- and limit red meat and processed meats.
  • Avoid alcohol or limit it to no more than one drink a day for women and up to two drinks a day for men.
  • Don’t smoke.
