Eye cancer symptoms: Seven warning signs you have the deadly disease in your eyes


EYE CANCER symptoms are not always obvious and they may only be picked up during a routine eye test. But it’s important to recognise any warning signs before the disease progresses. There are seven to watch out for.

Eye cancer symptoms can also be caused by more minor eye conditions, which is one of the first things to note.

But if you experience any signs you should get checked out by your doctor as soon as possible.

There are between 50 and 600 cases of eye cancer in the UK each year.

So what signs should you be looking out for? There are seven to be wary of, according to the NHS.


These include:

  • Shadows, flashes of light, or wiggly lines in your vision
  • Blurred vision
  • A dark patch in your eye that’s getting bigger
  • Partial or total loss of vision
  • Bulging of one eye
  • A lump on your eyelid or in your eye that’s increasing in size
  • Pain in or around your eye, although this is rare

The causes of eye cancer are not yet fully understood, but there are some reasons you might be more likely to develop it.

Bupa says having eyes that are a par colour, such as blue, grey or green can make you more likely to get eye cancer.

It’s also believed you’re more likely to get eye cancer if you are older, if you are white, with fair skin, if you have unusual brown spots in your eyes, and if you have lots of unusually shaped or large moles.

Being exposed to sunlight might be a cause. So going out in the sun too much without protection may increase your chance of eye cancer.

The health organisation adds: “Young children may get a form of eye cancer called retinoblastoma.

“In about four out of 10 children with retinoblastoma, it’s caused by a faulty gene. Often both eyes are affected.

“It’s not known what the cause is in the remaining children.”

Eye melanoma is one of the most common types of eye cancer and most commonly affects the eyeball.

The outlook for melanoma of the eye depends on how big the cancer is at the time it’s diagnosed and exactly which parts of the eye are affected, says the NHS.

It adds: “Overall about eight out of every 10 people diagnosed with a small eye melanoma will live for at least five years after diagnosis.

“About seven out of every 10 people diagnosed with a medium-sized eye melanoma will live for at least five years after diagnosis.

“About five out of every 100 people diagnosed with a large eye melanoma will live for at east five years after diagnosis.”

The eyes can indicate a number of different health conditions, including vitamin b12 deficiency.
