(RNS) — Last year, Mercy Haub, a 16-year-old student and pastor’s daughter from Seattle, was diagnosed with cancer. The diagnosis came not long after she’d raised more than $30,000 for cancer research and shaved her head in a sign of support for cancer patients. 

The teen, whose life’s dream is to become an oncologist, first began raising money for research after a friend’s father was diagnosed with cancer. She recently shared her cancer story on “The Ellen DeGeneres Show.” Mercy is now officially in remission.

During her treatment, she wrote this poem, which was inspired by children’s artwork hanging on the walls of the hospital where she was treated. 

Cancer

I know what that word means.
When you live 
knowing this thing 
inside of you 
has caused so much 
pain
it’s hard to forget.

I know what it means to be scared,
To tremble at night,
Dreading test results and bad news.
Ignorance is not bliss, 
Not when the other option tells a story
Of sleepless nights and nightless stays, all bleeding into 
one.
When a simple scan can spell disaster for 
your future, 
your plans, 
your hopes,  
your body, 
Uprooting everything to hurt.

I know what it means to be in pain,
To clutch your body,
ever curling tighter in hopes that
If I only make myself small enough 
the pain 
will do the same.
To dread a glance at the clock,
Ever wishing the days would pass faster, 
but 
there is always
So
Much
Day
Left.

I know what it means to be pitied,
To feel eyes from 
every angle upon my shoulders,
Their gazes caressing my bald head,
Cooing encouraging words and 
melancholy apologies,
Eyebrows furrowed and eyes wide 
as they witness tubing 
emerge from my body. 

I know what it means to mourn,
To envision all that could have been
And all that won’t be.
Wishes fall upon my closed ears,
My mind’s defense block trains of thought
For the conductor 
is sick.
Cancer.
I know what that word means. 

But I also know what it means to be brave.
To walk with force and resolve into something
I already know
Is going to be hell.
I know how to smile and wave at family and friends when they say hello
Even if
I feel like crying.
I know how to look on the bright side,
Or even simply the less dim side,
Just to see my parents try and

Secretly sigh their relief. 
I know what it means to fight like my life depends on it
Because
It does.
I know what it means to look at a new patient and say
“Hey,
I know it’s hard
But
You’re going to make it through.
I believe in you”
I know
Better than most
What it means to be brave.
