Testing

Tissue tests | Review

Tissue samples removed with a biopsy or surgery

will be sent to a pathologist. A pathologist is a doctor

who’s an expert in testing cells to find disease.

The pathologist will view the tissue sample with a

microscope to look for cancer cells. He or she will

also assess the features of the cancer cells to find

out the subtype.

Subtypes of RCC

RCC is the most common type of kidney cancer.

There are also many subtypes of RCC, based on

how the cancer cells look under a microscope. The

most common subtype by far is clear cell RCC.

Clear cells look very pale or clear when viewed with

a microscope. Other, less common subtypes are

papillary and chromophobe. There are also a number

of very rare subtypes of RCC. Collecting duct and

medullary are very rare forms of non-clear cell RCC.

When the cancer cells don’t look like any of the

subtypes, it’s called unclassified RCC.

Your health history and a body exam inform

your doctor about your health.

Imaging tests are used to find and confirm

kidney cancer.

Blood and urine tests check for signs of

disease.

A biopsy removes small samples of tissue to

test for cancer.

Clear cell RCC is the most common subtype.

The only symptom I ever had was

blood in urine - never any pain. I am

so happy to be here today. 45 years

old today, with no limitations. So

lucky to catch it so early.
