The symptoms of retinoblastoma may vary from one individual to another, but in general, a patient with this cancer should see an ophthalmologist as soon as possible. In some cases, a tumor in the eye may be the result of a less serious ailment. These tumors develop in the retina due to a mutation in a gene that controls cell division. Because the affected gene is damaged randomly, the tumor may only be located in one eye.

Some of the earliest symptoms of retinoblastoma include a "white pupil" that is a round black opening in the center of the eye. The pupil will appear white when light shines into it, and the child may have trouble walking or moving around the house. In addition, the eyeball may grow to a larger size than normal and the pupil will become white. Retinoblastoma is difficult to detect in an infant or child. However, there are other eye diseases that may cause similar symptoms.

In children who have the hereditary form of retinoblastoma, it is important to undergo regular eye exams so that doctors can watch for early signs of the disease. The condition usually develops before the age of six, though it may occur earlier if there are family members who have had the condition. After an initial eye exam, the doctor may recommend a series of imaging tests to determine the exact type of cancer. If the disease is detected early, treatment options can be initiated.

Treatments for retinoblastoma depend on its stage. If it has spread beyond the eye, the cancer may be in the central nervous system or the liver. The treatment of retinoblastoma depends on the stage at which it first manifested itself. If the cancer has spread outside of the eye, treatment may be more difficult. As such, early diagnosis and treatment are crucial for the successful outcome of treatment.

Retinoblastoma is a hereditary disease, where a particular gene is mutated. Hereditary retinoblastoma affects both eyes. In addition to affecting only one eye, hereditary retinoblastoma increases the risk of other cancers. Genetic testing is recommended for children with a family history of the disease.

Retinoblastoma is caused by genetic mutations in the RB1 gene. Hereditary cases manifest with multiple tumors in both eyes, while non-heritable cases usually occur in one eye. Hereditary retinoblastoma is usually passed down through parents, while the non-hereditary form develops later. The cancer cells that cause retinoblastoma are responsible for most retinoblastomas.

The prognosis of retinoblastoma depends on the size of the tumor and whether it has spread beyond the eye. Surgery or chemotherapy may be recommended for larger tumors. Sometimes, the eye may have to be removed. Sometimes, the tumor may be removed and a new artificial eye is implanted in its place. The prognosis for this condition is usually good if detected early.

Chemotherapy is a treatment for retinoblastoma. The drugs in this type of chemotherapy are delivered directly into the eye via the ophthalmic artery, which is the main blood supply of the retina. Although effective, the radiation therapy may result in retinal damage, leading to vision loss. However, in children with bilateral retinoblastoma, radiation therapy is the standard of care.

Retinoblastoma is a cancer of the retina, which affects the back of the eye. It usually affects children under the age of five, but can happen in either eye. In most cases, if it is detected early, the disease can be treated and cures are achieved. The treatment for this cancer can be lifesaving, and early diagnosis is critical for preventing vision loss and stopping the cancer from spreading to other parts of the body.
