Battling cancer is no easy task — especially when the one afflicted is just a small child.

When Madeline Pyle was 5 years old, she and her family received gut-wrenching news. Madeline had been diagnosed with leukemia, as stated in the YouTube description of the video featured below.

Leukemia is cancer of the blood and bone marrow, according to the Mayo Clinic. In people with leukemia, "bone marrow produces abnormal white blood cells, which don't function properly." The disease is commonly treated with chemotherapy. 

Eighteen and a half years after Madeline's fateful trip to the doctor, she reached a major milestone in life. After successfully battling cancer as a child, she was getting married. Her father, Ed Pyle, had quite the surprise in store for his daughter on her special day. Fortunately, a videographer was there to capture said surprise on film.

In attendance at Madeline's wedding ceremony, much to her amazement, were three members of the medical staff who diagnosed and treated her as a child. When Madeline caught a glimpse of those who had saved her life so many years ago, it was clear that she was overcome. The trio of doctors and nurses was there to present flowers to the soon-to-be-married couple, who then offered the flowers to Mary, the Mother of Jesus — as is common in many Catholic weddings, according to Together for Life.

Dr. Maxine Hetherington of Children's Mercy Hospital in Kansas City, Mo., was the one to diagnose Madeline, according to the speaker who introduced her at the wedding. Dr. Alan Gamis treated her, while Joy Bartholomew, a nurse, was the one who "inspired Madeline to be a nurse and taught her how to swallow up to 20 pills a day." After the touching interaction between the two parties, Madeline and her husband made their way toward the statue of Mary. 

The video was posted in August of last year though no specific date for the wedding is listed. You can watch the emotional moment unfold below.
