Introduction to Neuroblastoma in Babies

Neuroblastoma is a type of cancer that starts in specialized nerve cells called neuroblasts. These cells are crucial for developing the nervous system, but in neuroblastoma, they grow uncontrollably and form a tumor. It’s a serious disease, but early detection and treatment can significantly improve outcomes.This condition primarily affects infants and young children, with the majority of cases diagnosed before the age of 5.

While it can occur in older children and even adults, the incidence is considerably lower in these age groups. Understanding the early signs and symptoms is vital for timely intervention.

Typical Age Range of Affected Babies

Neuroblastoma is most commonly diagnosed in infants and young children, with the peak incidence occurring in the first few years of life. The vast majority of cases are diagnosed before the age of 5. This age range highlights the importance of close monitoring and vigilance in the first years of a child’s life.

Signs and Symptoms of Neuroblastoma, How to detect neuroblastoma in babies
