Getting diagnosed with prostate cancer
You usually have a number of tests to check for prostate cancer. These include:
a digital rectal examination
a PSA blood test
scans
taking a sample of your prostate gland- this is called a biopsy
Most people start by seeing their GP. They can do some tests to help them decide whether you need a referral to a specialist. The tests your GP might arrange include:
an examination of your prostate gland (digital rectal examination)
a prostate specific antigen (PSA) blood test
Your doctor checks your prostate gland for abnormal signs such as lumps or hard areas. This is also called digital rectal examination (DRE).
To examine your prostate, the doctor puts a gloved finger into your back passage (rectum).

The PSA test measures the amount of prostate specific antigen (PSA) in your blood. PSA it’s a protein made by both normal and cancerous prostate cells.
It’s normal for all men to have some PSA in their blood. But a PSA level higher than what would be expected for someone of your age can be a sign of prostate cancer.

Depending on the results of your tests, your GP might refer you to a specialist. You usually see a urologist. This is a doctor who specialises in treating problems of the urinary tract system such as the prostate, bladder and kidneys.
Your specialist usually does more tests. These might include:
an MRI scan (MRI)
biopsy
CT scan
bone scan
PET scan
During a biopsy, your doctor takes samples of tissue from your prostate. They send the samples to a laboratory and a doctor looks at them under a microscope to check for cancer.
There are 2 main ways to have a prostate biopsy:
transperineal biopsy - the needle goes through the
transrectal ultrasound scan (TRUS) guided biopsy - the needle goes through the wall of the
Most hospitals in the UK now use transperineal biopsy to diagnose prostate cancer.
Your doctor puts a needle into the prostate through the skin between the testicles and the back passage (rectum). This is the perineum. They then take a number of samples from the prostate to examine under a microscope.
You usually have this biopsy under . Or you might have it in the operating theatre under a general anaesthetic. This is when you are asleep and don’t feel anything.

Your doctor takes a series of small tissue samples from the prostate to examine under a microscope. You have the biopsy through the back passage (rectum) using a transrectal .
A TRUS guided biopsy can be uncomfortable. You usually have a to numb the area and reduce any pain.

If you have a biopsy that shows that you have cancer cells in your prostate, then you may have more tests to work out where and how big the cancer is. This is called staging the cancer.
The tests you have next depend on the type of cancer you have. The tests you might have include:
CT scan
bone scan
PET scan
CT (or CAT) scan stands for computed (axial) tomography. It is a test that uses x-rays and a computer to create detailed pictures of the inside of your body.
You might have a CT scan to find out whether the cancer is in the prostate only or whether it has spread to other parts of your body.

A bone scan shows up changes or abnormalities in the bones. You might have a bone scan to find out if prostate cancer has spread to the bones.

A PET scan is a test that creates 3 dimensional (3D) pictures of the inside of your body. PET stands for positron emission tomography. It uses a mildly radioactive liquid called a radioactive tracer. You might have a PET scan to find out if your cancer has spread.

The tests you have helps your doctor find out if you have prostate cancer and how far it has grown. This is the stage of the cancer.
Read about the stages of prostate cancer
This is important because doctors recommend your treatment according to the stage of the cancer.

Prostate cancer is cancer of the prostate gland. The prostate gland is part of the male reproductive system, and is at the base of the bladder.
Prostate cancer doesn't usually cause any symptoms in the early stages.
The PSA test is a blood test that measures the amount of prostate specific antigen (PSA) in your blood. It can help to diagnose prostate cancer.
Doctors use Grade Groups and other information to divide prostate cancer into 5 groups called the the Cambridge Prognostic Group (CPG). The stage tells you the size of the cancer and whether it has spread.
You may have a choice of treatments such as surgery or radiotherapy. Or your doctor might suggest that they monitor your cancer instead of treatment straight away.
Prostate cancer is cancer that starts in the prostate gland. The prostate gland is found at the base of the bladder and is about the size of a walnut.
