Mom Who Delayed Cancer Treatments While Pregnant Gives Birth to Healthy Boy

Kim Valliancourt was diagnosed with a brain tumor.

— -- A New York woman who delayed treatment for a brain tumor due to her pregnancy gave birth to a healthy baby boy this weekend, according to her family.

Kim Vaillancourt gave birth to her son Wyatt Eli on Friday, months after being diagnosed with a dangerous brain tumor.

"The family is 'over the moon excited' to welcome Wyatt to their extraordinary family," read a post from a fundraising site for the family. "Wyatt Eli meaning 'little warrior sent by God' is wrapped in love by parents Kim and Phil, brother, sisters, family, and countless friends."

"If she wasn’t pregnant she would have slipped it off," family spokeswoman Jenna Koch told ABC News in an earlier interview. "She’s not one to get it seen or treated."

Koch said that Vaillancourt expected to undergo chemotherapy and radiation, when she resumes her cancer treatment.
