Eye Cancer


What is eye cancer?
There are two different types of eye cancer Primary intraocular cancer and Secondary intraocular cancer. Primary intraocular cancer is a form of cancer that starts in the eyeball. Secondary intraocular cancer starts somewhere else and travels into the eyeball the most common cancers that travel into the eye are lung and breast cancer. The place in the eye that cancers are most likely to spread is the uvea.

Who is at risk?
It all depends on the age of the person who has cancer. For example Retinoblastoma (a cancer arising from cells in the retina) is most likely to occur in children while on the on the other hand Intraocular melanoma which usually occurs in adults (9 out of 10 intraocular melanomas develop in the choroid).

How is it diagnosed?
Some signs and symptoms of eye cancer are:
  • Problems with vision (blurry vision or sudden loss of vision)
  • Floaters (spots or squiggles drifting in the field of vision) or flashes of light
  • Visual field loss (losing part of your field of sight)
  • A growing dark spot on the iris
  • Change in the size or shape of the pupil
  • Change in the position of the eyeball in the socket
  • Bulging of the eye
  • Change in the way that the eye moves in the socket
Pain is rare except in cases when it spreads outside of the eye. Then an eye exam goes into process after that an image test is started then finally a Biopsy is preformed (in this procedure, a small, hollow needle is passed in to the eye and cells from the tumor are sucked up into a small syringe).
How do you prevent it?
Some ways to prevent eye cancer are:

  • Keep your immune system healthy through diet, exercise, proper nutrition and safe sexual habits
  • Try not to expose yourself for long periods of time to the sun’s light
  • Wear protective eye-wear that blocks at least 99 percent of ultraviolet rays
  • Limit your exposure to radiation
  • Prevent exposure of your eyes to chemicals and carcinogen
  • Talk to your doctor about other steps to preventing eye cancer

The most effective of these examples would have to be keeping your immune system up. If your immune system shuts down there might be a chance that you could get more than just cancer.
