Sister Act: Facing Cancer, and the Future, Together

The vanKoeverden sisters of Rochester, MN, want you to know they were Ana and Elsa way before the Frozen franchise came along. And to answer what starstruck little kids ask all the time: No merchandise. No millions. Not even free movie tickets.

Like their animated counterparts, Ana, 14, and Elsa, 12, are brave, strong and, yes, beautiful. But instead of an epic adventure to free their kingdom from eternal winter, the threat being faced by the real-life sisters, alongside their parents, is brain cancer.

A few months after her third birthday, Ana was diagnosed with a Grade 1 pilocytic astrocytoma, a slow-growing tumor in her brainstem. She had been vomiting on-and-off and, after ruling out simple causes, doctors at Mayo Clinic—where Ana’s Dad, Kevin, is a nurse anesthetist and Mom, Heather, worked as an occupational therapist—scheduled an MRI.

The tumor that turned the family’s life upside down was in a place too delicate for surgery, so Ana’s first treatment was a 15-month chemo regime. Two years later came another nine months of chemo, followed by six weeks of radiation. Then after four years of stable scans, the tumor grew again.

Among Ana’s most favorite Beads of Courage are the hearts, which mark the end of a chemo cycle. She keeps the beads in a canister, on the outside of which people who have been part of her health journey have added their signatures.

It has been stubbornly persistent since 2017, and Ana is now on her sixth line of treatment. That’s cancer-speak for the number of times and approaches doctors have used to attack the tumor.

Ana has more than 800 Beads of Courage to show for it. One for every needle poke, scan, dose of chemo or radiation or hospital stay over the past 11 years. But there are no beads for rashes, fevers, nausea, weight loss, exhaustion, missing school and having to modify so many activities for such a long time.

“When you look at me, you don’t think, ‘Oh, my God, she has cancer!'” Ana said. “But when you see all my beads, you’re like, ‘Oh, she has cancer.’ The beads help explain me, without any words.”

Heather and Kevin vanKoeverden, with daughters Ana, Elsa and Calla, the family’s Wirehaired Pointing Griffon. The breed is known for being loyal, vigilant and gentle, which Ana confirms. She said, “When I spend time with Calla, I feel like she’s always there for me. Whenever I sit on the couch, she’ll just come sit by me because she wants attention and wants us to love on her.”

Putting sister Elsa into words is trickier. Just 17 months old at the time of Ana’s diagnosis, she has little or no memory of when cancer wasn’t in the family picture. Glimpses of her spirit and soul show in the CaringBridge Journal that Heather and Kevin have been updating since 2008.

The day before Elsa turned 4, on May 3, 2011, Heather wrote, “Elsa has grown up as a ‘shadow survivor’ and knows nothing different than hanging out with kids without hair, playing doll-hospital and joining us on this journey and all that goes with it. As she matures, she takes on a new understanding of the story. This kid can come up with some amazing questions about God and how this whole deal works.”

She even wondered aloud when she might be getting cancer, too, as if it was a normal part of childhood, like well-child visits and immunizations.

Other Journal entries describe Elsa wanting to sell her toys to give money to Ana’s doctors for better medicine, helping Ana put on her shoes and coat for a post-chemo trip to the ER, and asking her parents, “When is this cancer ever going to go away?”

With no answer to this question, the vanKoeverden girls simply keep going.

For Ana, it’s mornings at school and afternoons to rest, recover and do homework. Then it’s off to serve as manager of the high school girls basketball team, unless fatigue and nausea interfere. “I’m feeling about 50% right now,” she said.

She has also taken over from her parents much of the writing on her CaringBridge Journal, providing health commentary from a 14-year-old’s perspective—”This tumor is stupid”—and updates on her “long-overdue” bedroom remodel.

Ana’s tumor has been pressing on the part of her brain that controls movement of her legs and feet, so horseback riding helps strengthen her dorsiflexors, the muscles that help lift her feet. Ana calls the muscles her “horsey flexors,” mostly to tease her mom. Ana usually rides an easygoing horse named Mac, while Elsa has a bit of a wilder ride with Lily.

About her sister, Ana recently wrote, “Elsa is just being her crazy self. She’s liking middle school and she does really well. It’s totally unfair how little she has to study. Even though we have our days, she does show up when I need her. Her life gets changed by all the stuff happening to me, too.”

Elsa prefers the view from horseback, and would like to ride much more often than her schedule permits. She would also like to have much more time with electronics than her mother would consider plenty.

Her view about Ana’s cancer is wise, practical and inspirational: “Just think less and live more, for Pete’s sake! If all you do is worry, if things would actually get bad, you will have lived a whole life of worry. Don’t worry until you have to. Just have fun.”

    What brave girls Ana and Elsa are , to confront living with cancer from an early age. My hope is for both of them to show the compassion they’ve shown throughout their lives. Reading about them gives hope in these dark tiomes. Blessings.

  • Olga Barbanel

    What an amazing relationship your family has! Beautiful family inside out – Elsa will beat it for good! Love the last passage the most – live your life to its fullest and worry when you have to.. you are all very lucky!

  • Loretta F. Hill

    These girls are special and caring! Cancer is bad for anyone, but I can’t imagine a kid trying to deal with it and keep on going.

  • Lisa D Day

    What an amazing family. My heart truly aches for all of them, but especially Ana. Thank you for shining some light on this gloomy day here in Central NJ. God bless Ana, Elsa and Mom and Dad! And god bless those beautiful horses as well!

  • Delores Peters in California

    My cousin Renee Hirte is working on getting grants for her brain tumor treatment. Once she gets the funding she will start clinical trials at the Mayo Clinic. She usually needs a small piece of the tumor to find the best treatment that eradicates the tumor. Since both of the parents work at Mayo they can talk with the cancer doctors there to see if Ana can get into Renee’s clinical trials.

    I love the idea of the beads. I have always thought I should have kept all my arm bands from hospital admissions and E.R. visits. Since I’m now 65 , it would be quite long! I have had a chronic disease since I was about 16; and now towards the end as I’on TPN. It has been a long interesting trip. You seem to be a brave strong girl, with a great family to support you, and I wish you the moon and the stars and a life to live as long as you are given. You know it’s not any easy ride, but we can choose to be the red car that shines, or the old rusty cruiser that chugs along. I prefer somewhere in between. I also have had bouts with bladder cancer, the “good kind” of cancer my doctor told me. It is crohns disease that got me! You stay strong keep your head up . It’s wonderful you have a sister and family to support you. Wishing you well my dear ,and stay warm this winter! Wendy Will

    Thank you for this interesting article. I have known Anas story almost all the time, thanks to her grandmam Fellows. I used to be an exchance student on Swan Bros farm in 1966. After that I visited to Allan and Hilding with my wife Marja-Leena and son Pekka in June 1990. I remember, when Heather was playing with Pekka on farm yard. Ana has been very strong young lady. We pray for you here. Greetings from Finland. Esko Kaukonen.

    Prayers for God’s healing—-such a sweet story of two sisters too—and I have two sisters and three brothers, so I can understand the love between siblings for sure! I have had ovarian cancer and am cancer free now—five years but have Lynch syndrome so have to be tested for a lot of cancers. Praying you stay close to the Lord and that healing is in your future. God bless!

  • Daisy

    Lovely family, thanks for sharing. Hope you don’t mind me sharing this positive news story about a young cancer survivor.

  • Shelley Rae Buck

    Anna & Elsa, You are an inspiration beyond what your namesakes brought to the big screen! Keep living life to its fullest and leave worry behind! That’s what my late son, Ryder, lived by. It wasn’t cancer that took him from us. But we try to live by his philosophies which he developed during his treatment. I will share your story with my husband who co-directed the Frozen movies. If you’d like to read more about Ryder, you can find the book I wrote about his life and light at ryderbuckmusic.comWishing you the best life has to offer!-Shelley Buck
