Cancer staging

Possible biopsy sites in

the abdomen and pelvis

Surgery is used for ovarian

cancer staging. Biopsy samples

will be taken from the tumor

as well as other organs and

tissues near the ovaries. This

may include the diaphragm,

omentum, peritoneum, ascites,

and nearby lymph nodes.

The number of samples taken depends on how far

your doctor thinks the cancer has spread. Biopsy

sites may include the following:

†

†

Nearby lymph nodes

– groups of special

disease-fighting cells

†

†

Pelvis

– the area below the belly (abdomen)

between the hip bones

†

†

Abdomen

– the belly area between the chest

and pelvis

†

†

Diaphragm

– the muscles below the ribs that

help a person breathe

†

†

Omentum

– the layer of fatty tissue covering

organs in the abdomen

†

†

Peritoneum

– the tissue that lines the inside

of the abdomen and pelvis and covers most

organs in this space

†

†

Ascites

– abnormal fluid buildup in the

abdomen

If you don’t have ascites, your doctor may “wash”

the space inside your belly (peritoneal cavity) with

a special liquid. This is called a peritoneal washing.

Samples of the liquid will then be tested for cancer

cells. These samples are called peritoneal washings,

but are often referred to as “washings.”
