What is Eye Cancer?What the the sufferings from the eye-cancer? 

Eye cancer can occur in any of the structures of the eye. It can start in the eye, called primary intraocular cancers, or result from the spread of cancer in another area of the body, known as secondary intraocular cancers. They found eye cancer in any of the eye`s three major parts. One part is the eyeball, which is filled with a jellylike substance called the vitreous humor. The eyeball contains three layers:        

1.sclera, which is the outer wall uvea, which provides nourishment for the eye retina, which sends information from the eye to the brain The uvea is the central opening in the iris and contains the ciliary body, which controls the shape of the lens and focuses the eye, and the choroid, which contains pigmented cells and connective tissue. 

2.Another part of the eye is the orbit. This refers to the tissues and bones that surround the eyeball. The third part contains the appendage structure, including the eyelids and lacrimal glands. Scientists are studying how changes in DNA in genes cause cancer of the eye. Changes in DNA can turn on oncogenes that help cancer cells grow and divide, or turn off tumor-suppressing genes that kill or slow growth of cancer cells. These changes allow healthy cells to grow out of control and form tumors. Types of Eye Cancer Eye cancer is rare. The American Cancer Society estimates 3,320 new cases of eye cancer that killed 400 peoplein 2021. The most common types of primary intraocular cancer differ between adults and children. In adults, the most common form is melanoma. Intraocular melanoma begins with pigment cells that give color tothe eye. Choroidal melanoma accounts for 85% of all primary intraocular cancers, and 85-90% of tumorsoccur in the choroid. Conjunctival melanoma is a less common type in adults and affects the thin, transparent material that covers the sclera. The second most common form in adults is non-Hodgkin's lymphoma (primary intraocular lymphoma). This usually only occurs in people with immune system disorders.Orbits and appendages are other primary eye tumorsthat are less common in adults. In children, the most common type of primary eye cancer is retinoblastoma. The second most common form is medullary epithelioma, which is very rare. Secondary intraocular cancer is more common than primary intraocular cancer. For example, about 90% of melanomas in the eye start on the skin. Other common sources of origin are the breasts or lungs. However, skin cancers can still be a primary cancer if they happen on the eyelid. Signs of eye cancer VIEW GALLERY3 Many people trusted Source with eye cancer may have no symptoms until the tumor is more advanced. Signs and symptoms that a person should report to a healthcare professional include: blurry vision or sudden loss of vision floaters, which are specks that move around in vision, or flashes of light visual field loss a growing dark spot on the iris change in size or shape of the pupil change in position of the eyeball bulging of the eye change in the way the eye moves There is rarely pain with eye cancer unless the tumor is large. We may associate these symptoms with other conditions and may not indicate cancer.

People with different types of moles and freckles on their skin and eyes are more likely to develop cancer of the eyes. Family history: Having an immediate family with a history of eye cancer can also increase a person`s risk. More research will help experts understand if certain factors like sunlight exposure, particular occupations, or skin melanoma cause eye cancer. 

Prevention tips Experts do not know the exact cause of eye cancer. 

The risk factors for eye cancer are known, but people who have them cannot change them. Although there is no proven link between eye cancer and sunlight, the American Cancer Society trusted Source recommends wearing UVprotected sunglasses when outside. 

The best type of sunglasses are all-round sunglasses that absorb 99-100% UVA and UVB.Treatment Before starting treatment for , the doctor will determine the size of the tumor and whether the tumor has spread to other parts of the eye, lymph nodes, or other parts of the body. This is called staging. Doctors can also rely on Source to examine cancer cells under a microscope to determine what type they are and how likely they are to respond to treatment. If the tumor is small or slow growing, doctors may recommend careful follow-up. 

Treatment begins whenthe tumor reaches a certain size or causes symptoms.The treatment plan may include reliable sources that combine several of the following: 

Surgery: The type and extent of surgery depends on the location and size of the tumor. The range of tissue removal can range from a small portion of the eye structure to complete removal of the eye (enucleation). Surgery can result in the loss of some or all of the eyesight in the eye.

Radiation: Various radiation therapies are available. Doctors focus on high-energy x-rays from machines near the cancer or insert a disc containing radioactive seeds directly into the eye (brachytherapy or plaque therapy). Radiation is more common than surgery because it can maintain vision and appearance.

Laser Treatment: Doctors use infrared rays to heat and kill tumors. Doctors usually use this method for small eye tumors because they can cause bleeding, retinal detachment, blockage of blood vessels in the eye, and recurrence of cancer of the eye. 

Chemotherapy: This is usually not the first treatment for cancer of the eye unless it has spread to other parts of the body.
