What are the stages of eye cancer?

Staging means finding out how big the cancer is and if it has spread to other parts of your body. Staging will help your doctor to plan the best treatment for you.

The staging system normally used in eye cancer is called TNM. 

This stands for:

• Tumour (T): How big is the tumour?
• Node (N): Is there cancer in your lymph nodes?
• Metastasis (M): Has the cancer has spread to other parts of your body?

Your doctor often uses this information to give your cancer a number stage – from 1 to 4.

A higher number, such as stage 4, means a more advanced cancer.

Your doctor may use a different staging system, depending on the type of eye cancer you have.
