Jennifer Clark’s daughter, Abby, is battling leukemia and while that itself is tremendously tragic, Clark said her daughter is a “fighter.”

Video shared by Clark following one of Abby’s treatments is a testament to that.

Abby is seen in footage recorded by her mother on May 4 sitting in her hospital bed in Katy, Texas. She had just finished her treatment and as part of that treatment, Abby had to be in isolation for nine days.

A few seconds later, Abby’s brother entered the room, saying, “I’m here!” Abby can be heard gasping and calling out to her brother.

Abby then reached her arms out, telling her brother to “come here” for a hug.

What they’re saying:

Clark told Storyful that despite the “brutal experience” with the blood cancer, Abby “inspires us daily with how she takes it head on.”

Childhood leukemia

Leukemia is the most common cancer in children and teens, according to the American Cancer Society.

By the numbers:

Leukemia accounts for almost 1 out of 3 cancers.

About 3 out of 4 leukemia cases among children and teens are acute lymphocytic leukemia and most of the remaining cases are acute myeloid leukemia.

Dig deeper:

Acute lymphocytic leukemia is the most common in early childhood and is typically seen in children between two and five years of age.

While acute myeloid leukemia is slightly more common during the first two years of life and during teenage years, it tends to be more spread out across the childhood years, the ACS said.

Chronic leukemia is rare in children and most of the cases are chronic myeloid leukemia. This form of cancer tends to occur in teens.

Another rare form of leukemia is juvenile myelomonocytic leukemia. A patient who is diagnosed with this form of cancer has an average age of two and it’s slightly more common in boys than girls, according to the ACS.

Treating leukemia

Depending on the type of leukemia diagnosis a child receives, treatments can vary.

Treatment can range from radiation therapy, chemotherapy, targeted therapy with drugs, immunotherapy and high-dose chemotherapy. Stem cell transplants could also be a treatment option, according to the ACS.
