HEREDITARY RETINOBLASTOMA Meaning and
Definition
-
Hereditary retinoblastoma is an inherited form of cancer that affects the retina, a layer of light-sensitive tissue lining the back of the eye. It is characterized by the development of tumors in the retina, specifically in the cells responsible for detecting light and transmitting visual information to the brain. This condition is caused by a genetic mutation that is passed down from parents to their children.
Retinoblastoma usually occurs in early childhood and can affect one or both eyes. In cases of hereditary retinoblastoma, individuals inherit a mutated copy of the RB1 gene from one or both parents, which increases their susceptibility to developing this type of cancer. The RB1 gene is responsible for producing a protein that helps regulate cell division and prevent the formation of tumors.
Symptoms of hereditary retinoblastoma may include a white discoloration in the pupil, commonly referred to as a "cat's eye reflex" or leukocoria. Other signs may include poor vision, redness or swelling in the eye, or misalignment of the eyes. If left untreated, hereditary retinoblastoma can lead to vision loss or other complications.
Treatment for hereditary retinoblastoma may involve a combination of therapies, including chemotherapy, radiation therapy, laser therapy, or surgery. The specific treatment approach depends on the size, location, and number of tumors present, as well as the age and overall health of the individual.
Regular follow-up examinations and genetic testing are important for individuals with hereditary retinoblastoma and their families to detect any potential signs of the disease early on and develop appropriate treatment plans. Genetic counseling may also be recommended to assess the risk of passing the mutated gene to future generations and discuss family planning options.

Etymology of HEREDITARY RETINOBLASTOMA
The word "Hereditary Retinoblastoma" is composed of two parts:
1. Hereditary: The term "hereditary" is derived from the Latin word "hereditarius" which means "of inheritance". It comes from the word "hereditas" which means "inheritance" or "legacy". In the context of medicine, "hereditary" refers to a condition or trait that is passed down from parents to their offspring through genes.
2. Retinoblastoma: "Retinoblastoma" is a compound word that consists of two elements. "Retino" is derived from the Latin word "retina", which refers to the light-sensitive tissue lining the inner surface of the eye. "Blastoma" comes from the Greek word "blastos" meaning "bud" or "germ".
