Why children with polyps need specialized care

Gastrointestinal polyps can lead to serious health issues. Children with certain types of polyps may be at risk for developing various cancers, including gastrointestinal cancer. They may also have gene mutations that require specialized care and further testing of siblings and parents. This is why Children's Mercy is dedicated to providing comprehensive care supported by the latest research and treatment options.
