Staging and grading of vaginal cancer

The stage and grade of the vaginal cancer describes its size, whether it has spread and how quickly it may develop.

Staging of vaginal cancer

The stage of vaginal cancer describes:

  • where it is
  • how far it has grown from where it started
  • if it has spread.

Your cancer doctor will tell you the stage of the cancer when they have all your test results. Knowing the stage of the cancer helps your doctors advise you on the most appropriate treatment.

Number staging system

Vaginal cancers are usually staged using a number system. A number between 1 and 4 is given to the tumour, depending on:

  • its growth in the vagina and surrounding tissues
  • whether it has spread to lymph nodes or other organs.

Lymph nodes are part of the lymphatic system, which helps protect the body against infection and disease. There are groups of lymph nodes throughout the body. They are linked by fine tubes containing lymph fluid.

Stage 1

The cancer is only in the vagina.

Stage 2

The cancer has grown through the wall of the vagina.

Stage 3

The cancer has spread to the wall of the pelvis and/or has spread to nearby lymph nodes.

Stage 4

The cancer has spread to other organs. This can be divided into:

  • Stage 4A - The cancer has grown into organs nearby, such as the bladder or the back passage (rectum).
  • Stage 4B - The cancer has spread to organs further away in the body, such as the lungs. This is called secondary or metastatic cancer.

Grading of vaginal cancer

Grading refers to the appearance of the cancer cells under the microscope. It gives an idea of how quickly the cancer may develop:

  • Low-grade (grade 1) means the cancer cells look very similar to normal cells. They are usually slow-growing and less likely to spread.
  • Moderate-grade (grade 2) means the cancer cells look more abnormal. They may grow more quickly.
  • High-grade (grade 3) means the cancer cells look very abnormal. They are more likely to grow quickly or spread to other parts of the body.
