What Are the Key Statistics About Retinoblastoma?
Retinoblastoma is a rare disease. Only about 200 to 300 children are diagnosed with retinoblastoma each year in the United States. It is more common in infants and very young children than in older children. The average age of children when they are diagnosed is 2. It rarely occurs in children older than 6.
About 3 out of 4 children with retinoblastoma have a tumor in only one eye. In about 1 case in 4, both eyes are affected.
Retinoblastoma occurs about equally in boys and girls and in different races and ethnicities. It also occurs equally in the right or left eye.
Overall, more than 9 out of 10 children with retinoblastoma are cured, but the outlook is not nearly as good if the cancer has spread outside of the eye.
