- Retinoblastoma is eye cancer that starts in the retina – the delicate lining in the eye. Retinoblastoma most commonly affects young children but can rarely occur in adults.
Your retina is made up of nerve tissue that senses light as it passes through the front of your eye. The retina sends signals through your optic nerve to your brain, where those signals are interpreted as images.Retinoblastoma is a rare form of eye cancer and the most common type of eye cancer in children. Retinoblastoma can occur in one or both eyes. Retinoblastoma Treatment in Nizamabad
symptom
Because retinoblastoma mainly affects infants and young children, symptoms are rare. Some of the signs you may notice include:
- A white color in the center circle of the eye (pupil) when light is shining in the eye, e.g. B. When taking a flash photo
- Eyes that seem to be looking in different directions
- Eye redness
- Swelling of the eyes
The reasons
- Autosomal dominant inheritance model
- Autosomal Dominant Inheritance PatternOpen Context Dialog
- Retinoblastoma occurs when nerve cells in the retina develop genetic mutations. These mutations cause cells to keep growing and multiplying when healthy cells die. This accumulated cell mass forms a tumor.
Retinoblastoma cells can penetrate further into the eye and surrounding structures. Retinoblastoma can spread (metastasize) to other areas of the body, including the brain and spine.
In most cases, it is not known what causes the genetic mutations that lead to retinoblastoma. However, it is possible for children to inherit a genetic mutation from their parents. Retinoblastoma Treatment in Nizamabad
prevention
In most cases, doctors aren’t sure what exactly causes retinoblastoma. Hence, there is no proven way to prevent the disease.Prevention for families with hereditary retinoblastoma
Prevention of retinoblastoma may not be possible in families with the inherited form of retinoblastoma. However, genetic testing tells families which children are at increased risk of retinoblastoma, so eye exams can begin at an early age. In this way, retinoblastoma can be diagnosed very early – when the tumor is small and there is still a chance of healing and preservation of vision.
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 for other related cancers
Your other children are at risk for retinoblastoma and other related cancers, so they may start eye exams early
You and your partner have the opportunity to pass the genetic mutation on to future children. Retinoblastoma Treatment in Nizamabad
