Eye Cancer Therapy
Eye cancer is the cancer that originates in the eyes. There are two types of eye cancer. One is primary eye cancer and the other is malignant eye cancer. Primary eye cancer is the cancer in which the cancerous cells originate in the eye itself and malignant eye cancer is the cancer in which cancerous cells spread to the eye from the other body parts. Eye cancer is a rare type of cancer. It is also called as silent killer cancer. The symptoms of eye cancer appear in the later stages of cancer. Hence, regular visit to the eye specialist is recommended as he is the only one who can diagnose eye cancer in its early stages. Retinoblastoma is a type of eye cancer that is found in children whereas ocular melanoma is a type of eye cancer that can be found in adults group.
Eye cancer therapy:
There are basically three dominant cancer treatments- radiation therapy, chemotherapy and surgery. Here, in eye cancer laser therapy is also used to treat the cancer.
The main objective of the radiation therapy is to destroy the cancerous cells. However, while destroying cancerous cells, surrounding normal and healthy cells also get destroyed. In radiation therapy, high energy radiation is used. X-rays, gamma rays or charged particles are used for the radiation. The radiation damages the DNA structure of the cells that are responsible to pass genetic information from one generation to the other generation. The radiation therapy can directly damage the DNA structure or can create free radicals or charged particles that eventually destroy the DNA structure.
Radiation therapy can be of two types- external-beam radiation therapy and internal radiation therapy. The type of radiation therapy depends upon many factors such as the size of the tumor, the type of cancer, location of cancerous tumor in the body, patient's age and medical history and conditions.
Chemotherapy is generally used to treat lymphoma in the eye. In this therapy, anti-cancer drugs can be directly injected into the veins or can be taken orally. In intraocular lymphoma eye, the drug is directly injected into the eyes allowing the use of higher doses of drugs without severe side-effects. Side effects of chemotherapy include hair loss, loss of appetite, fatigue, mouth sores, nausea and vomiting, low resistance power, diarrhea and easy bleeding due to bruising. Chemotherapy is extremely beneficial in treating cancerous cells that have spread to the other body parts.
Eye cancer surgery option is carried out when there is no other option. In surgery, entire eye can be removed if nothing works out. Surgery of eye is carried out by ophthalmologists. In most of the eye cancer surgeries, tumor is removed and there is no need to remove the entire eye ball. Sometimes, in treating eye cancer, part of the eye can be removed. If there is severe case then the entire eye can be removed. You can go for the process of prosthesis after the removal of eye ball. Prosthesis is the artificial implant. Here, in eye cancer an artificial eye can be fitted into the socket. However, the cost of prosthesis is quite huge. But, if you don't want to compromise on your looks then prosthesis is a good option that you can consider.
Laser therapy can also prove to be beneficial in effective treatment of eye cancer. In this therapy, highly focused beam of light is used to treat eye cancer. Transpupillary thermotherapy (TTT) is mostly used to treat intraocular melanoma. Infrared light is used to heat the tumor and eventually kill it. Possible side-effects of laser therapy include damage to some parts of the eye which can result in loss of vision. Hence, gather total information regarding the treatment before undergoing it. Mostly, the results of laser therapy are positive and do not result in loss of eyesight.
Above are few enlisted eye cancer therapies and treatments. Eye cancer can be successfully treated if detected early. Eye specialist is the only person who can detect your cancer in the initial stages through eye examination. Hence, regular eye check-up is a must.
