Natalie Cosman, 8-Year-Old Diagnosed With Ovarian Cancer, Is Now Cancer-Free

For Natalie Cosman and her family, the bad news came early one morning in June 2011. Melinda Cosman had rushed her then 7-year-old daughter to the emergency room the night before after her stomach pains became unbearable. Her doctors suspected it was constipation or a stomach bug, but called Natalie back into the ER in the morning to run an ultrasound in case of appendicitis.

Instead of a ruptured appendix, they found a 7-centimeter cyst on Natalie's ovary. After a biopsy confirmed the cyst was indeed cancerous, her doctors settled on a diagnosis -- ovarian cancer.

“She didn’t really understand,” Cosman told FOX News. “We explained to her what was going on as much as we could for a 7-year-old, but I don’t know if she gets how important her ovaries are.”

Fortunately, Natalie's cancer was caught at such an early stage that she was able to make a full recovery after six rounds of chemotherapy. Though she was unable to attend school during the treatment, Natalie will return to her Manchester, Conn., elementary school this month.

"I'm feeling great because I'm happy that everything is over," Natalie told FOX CT. "Now I just go for checkups every month."

An estimated 22,280 women are expected to be diagnosed with ovarian cancer this year. However, with the median age of diagnosis in the 60s, ovarian cancer in young girls Natalie's age, who have yet to undergo puberty, is extremely rare. Only 1.3 percent of women diagnosed with ovarian cancer between 2005 and 2009 were girls under the age of 20.

"Natalie was the first case that I heard about last year," Sharon Waxmundsky, a communications specialist with the National Ovarian Cancer Coalition, told WTNH. "Now, more and more cases are coming up with little girls."

That's why Natalie and her family are doing everything they can to spread awareness of ovarian cancer, and will reprise their role participating in the 5K Run/Walk to Break the Silence on Ovarian Cancer at Hammonasset Beach State Park in Madison, Conn., on Sept. 22. So far their team, Natalie's Tigers, has raised the most donations for the cause sponsored by the National Ovarian Cancer Coalition.

"Our goal is to make people realize it can happen to any female at any age," Cosman told FOX News.
