Prevention
By Mayo Clinic staffIn most cases, doctors aren't sure what causes retinoblastoma, so there's no proven way to prevent the disease.
Prevention for families with inherited retinoblastoma
In families with the inherited form of retinoblastoma, preventing retinoblastoma may not be possible. However, genetic testing enables families to know which children have an increased risk of retinoblastoma, so eye exams can begin at an early age. That way, retinoblastoma may be diagnosed very early — when the tumor is small and a chance for a cure and preservation of vision is still possible.
If your doctor determines that your child's retinoblastoma was caused by an inherited genetic mutation, your family may be referred to a genetic counselor.
Genetic testing can be used to determine whether:
- Your child with retinoblastoma is at risk of other related cancers
- Your other children are at risk of retinoblastoma and other related cancers, so they can start eye exams at an early age
- You and your partner have the possibility of passing the genetic mutation on to future children
The genetic counselor can discuss the risks and benefits of genetic testing and help you decide whether you, your partner or your other children will be tested for the genetic mutation.
