Retinoblastoma is a rare form of eye cancer that primarily affects young children. It originates in the retina, the light-sensitive tissue at the back of the eye. The prevalence of retinoblastoma varies across different populations and regions.
According to global estimates, retinoblastoma occurs in approximately 1 in every 15,000 to 20,000 live births. This means that it affects around 250 to 300 children worldwide each year. However, it is important to note that these figures can vary significantly depending on factors such as geographic location, genetic predisposition, and access to healthcare.
Retinoblastoma can be classified into two forms: hereditary and non-hereditary. The hereditary form, which is caused by a mutation in the RB1 gene, accounts for about 40% of all cases. Non-hereditary retinoblastoma, also known as sporadic retinoblastoma, occurs due to a mutation that happens during the child's development and is not inherited from the parents.
Early detection and prompt treatment are crucial for managing retinoblastoma and preserving vision. Regular eye examinations in infants and young children can aid in early diagnosis, leading to better outcomes. If you suspect any abnormalities in your child's eyes, it is essential to consult with a healthcare professional for further evaluation and guidance.
