Stage 2

The stage of a cancer tells the doctor how far it has grown and if it has spread. The tests and scans you have to diagnose your cancer will give some information about the stage.  But your doctor might not be able to tell you the exact stage until you have surgery.

Doctors use a simple 1 to 4 staging system for ovarian cancer. It is called the FIGO system after its authors - the International Federation of Gynaecological Oncologists.

Stage 2

Stage 2 ovarian cancer means the cancer has grown outside the ovary or ovaries, and is growing within the area circled by your hip bones (the pelvis). There may also be cancer cells in the abdomen.

It is divided into 3 groups:

  • 2a - the cancer has grown into the fallopian tubes or the womb
  • 2b - the cancer has grown into other tissues in the pelvis, for example the bladder or rectum
  • 2c - the cancer has grown into other tissues in the pelvis and there are cancer cells in fluid taken from inside your abdomen

The stage of your cancer helps your doctor to decide which treatment you need. Treatment also depends on:

  • your type of cancer (the type of cells the cancer started in)
  • where the cancer is 
  • other health conditions that you have

Treating stage 2 ovarian cancer

Stage 2, 3 and 4 ovarian cancers are classed as advanced. This means the cancer has spread away from the ovary. Surgery and chemotherapy can cure some advanced cancers. If your cancer can't be cured, the aim of treatment is to control the cancer for as long as possible.


You may have surgery as the first treatment for your cancer. The surgeon removes as much of the cancer as possible. This is called debulking. Whether you have surgery will depend on a number of factors, including:

  • where the cancer has spread to
  • your general health
  • how quickly the cancer is growing


After you have recovered from surgery, you will have chemotherapy.

If your surgeon could remove all your cancer, chemotherapy aims to reduce the risk of the cancer coming back. If the surgeon couldn't remove all the cancer, chemotherapy aims to shrink the cancer that has been left behind. Some women may then have further surgery.

From looking at the scans you had at diagnosis, your surgeon may decide that it would not be possible to remove all the cancer. In this case, you may have chemotherapy before surgery, to shrink the cancer and make it easier to remove. Chemotherapy before surgery is called neo adjuvant (pronounced nee-oh-ad-joo-vent) or primary chemotherapy.

Scans during chemotherapy

With primary chemotherapy, you have a scan halfway through the course. If the cancer is shrinking, you will then have surgery. You may hear your surgeon call this interval debulking surgery, or IDS. After the surgery, you have the rest of the course of chemotherapy.

Biological therapy

For some advanced cancers, you may have a type of biological therapy called bevacizumab with chemotherapy. Women with gene changes called BRCA1 or BRCA2 may have a drug called olaparib if chemotherapy is no longer controlling their cancer.
