Retinoblastoma is a type of eye cancer that develops in the light-sensitive lining of the eye, called the retina. Retinoblastoma can occur at any age but mainly occurs in children younger than 5 years of age and most often in those younger than 2.
Retinoblastoma may occur in one or both eyes, but rarely spreads to other parts of the body. Although it is the most common eye tumour in children, it is a rare childhood cancer and accounts for about 3-4% of childhood cancers.
There are 2 Types of Retinoblastoma:
- Inherited: Retinoblastoma is sometimes inherited from the parent; this is known as hereditary or germline retinoblastoma and is usually bi-lateral (in both eyes).
- Non-Inherited: This type of Retinoblastoma generally occurs in only one eye (unilateral)
The main challenge of treating Retinoblastoma is the prevention of blindness, however approximately 98% of children with retinoblastoma are cured.
