What Does Eye Cancer Look Like
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Unknown: The cause of most cancers is truly unknown although there are inciting factors like smoking. Cancer can occur in any dividing cell and the eye does have such cells. Cancer seems to be a mistake in cellular division. Cancer in the eye can come from this and also some cancers elsewhere can spread to the eye (metastasis). ...Read more
Sun exposure...: The most common eye cancer would be a basal cell carcinoma of the eyelid. This is largely related to excess sun exposure. A rare cancer in the eye is a retinoblastoma which can develop due to a mutation on chromosome 13, called the rb1 gene. This cancer has a good cure rate if detected early. A melanoma is another form of cancer in the eye that frequently harbor gnaq/gna11 mutations. ...Read more
Multiple steps: Any cancer, including eye cancer, is the result of multiple insults to the cells. Some of the insults may be inherited mutations, most are environmental injuries. The cumulative effect is to increase the proliferation of cells, non-response to usual regulation, ability to invade and metastasize. ...Read more
Changes in vision: Though rare overall, there are many types of cancer of the eye and orbit. For ocular tumors, defects in visual field or blurriness are common. Unusual symptoms including visual hallucinations have been described. For orbital lesions, symptoms can include bulging of the eye, paralysis of movement or double vision. If you have any such changes in one or both eyes, you should see your doctor! ...Read more
Eye cancer +sunlight: There is a strong correlation between sunlight exposure and skin cancers of the eyelids including melanoma and basal cell carcinoma. The incidence is much higher in light skinned races. If you have a suspicious lesion, see your ophthalmologist for evaluation. These tumors are of course mostly in older populations. ...Read more
Eye exam and others: Eye "cancers" are fairly common if the lids are included, and can range from lid tumors like basal cells, to potentially blinding and life threatening tumors like choroidal melanomas, retinoblastomas, as well as tumors spreading from another location. A thorough eye exam, and adjunctive tests like ultrasound, x-rays, and angiography are all used to diagnose ocular tumors. ...Read more
Eye symptoms: You will have some sort of symptoms like decreased vision for unclear reason that is also likely associated with headaches, or eye pain, sometimes with redness, edema or asymmetric bulging of the eye. However, those symptoms can also be caused by other conditions. So an eye examination by an ophthalmologist is very important. Eye cancer is a rare disease - this usually more in childhood. ...Read more
Location dependent: Cancer on the surface of the eye will cause swelling and redness with some discharge. Cancer of the retina (mostly melanoma) may affect vision and can cause inflammation in the eye. Another frequent type is metastatic usually from breast, lung or prostate. A few rare cancers may invade the interior of the eye or cause nodules on the iris. And the most common are skin cancers of the lids. ...Read more
Uncommon: Primary eye cancers are rare and include melanoma, and certain surface cancers. Kids can be born with eye cancer (retinoblastoma). The most common eye cancer is metastatic from other sources in the body. The eyelids however are a common site of skin cancer and this is very common. Any cancer in this region needs rapid and complete attention starting with your ophthalmologist. ...Read more
Heredity & unknown:
There are two major eye cancers, retinoblastomas that occur in childern and have an important heredity component in etiology. Melanomas occur in older people and other than exposure to sun, clear cut risk factors have not been defined. You may wish to consult the following webstie for more information.

Rare: Eye cancers are rare. There is one that occurs in infants and small children and another in pre-adolescent children. Melanoma occurs in adults and can occur at any age. The most common cancer found in the eye is cancer that has spread there from elsewhere, with breast and lung cancer being the most common. ...Read more
Rarely: Most eye cancers occur in one eye. Bilateral disease can be found in retinoblastoma in infancy as this is an inherited tumor commonly but not always present in both eyes. Adults get bilateral cancer in the eye in the rare instance of simultaneous metastatic cancer from another site like breast or lung. ...Read more
Rare: You are about as likely to get eye cancer as you are to win the lottery by buying a single ticket. ...Read more
Depends: Eye cancers include lesions on the lids which can cause focal redness, swelling and pain; lesions on the conjunctiva which lead to redness and irritation; iris cancers which can cause vision loss and iris distortion and choroidal cancers which include melanoma causing disturbance of vision or metastatic also disturbing vision. There are other rarers cancers as well. Consult your ophthalmologist. ...Read more
