Prostate cancer starts in the cells of the prostate. The prostate is a small gland that is just below the bladder and in front of the rectum (back passage).
Prostate cancer is a common cancer. In the UK about 48,600 men are diagnosed with it each year. Prostate cancer is more common over the age of 65. It can happen at a younger age but it is uncommon under 50. You have a higher risk of prostate cancer at a younger age if you are Black or have a strong family history of prostate cancer.
There are different types of prostate cancer
- early prostate cancer (or localised prostate cancer) – the cancer is only inside the prostate gland.
- locally-advanced prostate cancer – the cancer has spread through the capsule surrounding the prostate gland and may have started to spread into tissue or organs close by.
- advanced prostate cancer (or metastatic prostate cancer) – the cancer has spread to other parts of the body, such as the bones..
If you are a trans woman or are non-binary assigned male at birth, you also need to be aware of prostate cancer.
Prostate cancer symptoms only happen when the cancer is large enough to press on the tube that carries the urine from the bladder (urethra). If the cancer is in the early stage it may not cause any symptoms.
The prostate gland can also become enlarged due to a prostate condition called benign prostatic hyperplasia (BPH), which is non-cancerous.
The symptoms of benign (non-cancerous) prostate conditions and prostate cancer are similar. They can include:
- needing to pee more often than usual, especially at night
- difficulty peeing – for example, a weak flow or having to strain to start peeing
- feeling like you have not completely emptied your bladder
- an urgent need to pee
- blood in your urine or semen
- rarely, pain when peeing or ejaculating.
If you have any of these symptoms, it is important to have them checked by your doctor. Your GP can do tests (see Diagnosis of prostate cancer below) to find out if you need a referral to a specialist doctor.
If prostate cancer spreads, it usually goes to the bones. It may cause pain in the bones, such as in the back. This is called advanced prostate cancer (or metastatic prostate cancer).
Certain things called risk factors may increase the risk of developing prostate cancer. If you are black, you have a much higher risk of developing prostate cancer. You are also more likely to develop it at a younger age. Having a strong family history of prostate cancer is also a risk factor.
We have more information about the risk factors of prostate cancer.

You usually start by seeing your GP to have your symptoms checked. Your GP usually arranges some tests. The first tests used to diagnose prostate cancer are:
The doctor gently inserts a gloved finger (using lubricating gel) into your back passage (rectum). The rectum is close to the prostate gland so your doctor can feel for anything unusual in the prostate. A rectal examination test is quick and it should not be painful. It is also sometimes called Digital Rectal Examination (DRE).
The PSA test is a blood test to measure the level of prostate-specific antigen (PSA) in your blood. Prostate cancer often causes a raised level of PSA. But different things such as non-cancerous prostate conditions and getting older can also increase your PSA.
If your PSA level is raised or your rectal examination is unusual your GP refers you to a specialist doctor (urologist). Your GP may test your PSA level again if it is raised but your prostate feels normal.
At the hospital
A specialist doctor or nurse asks about your symptoms and any other medical conditions. They check if you have any risk factors for prostate cancer. The doctor may do another rectal examination and arrange another PSA test. They will talk to you about further tests you may have. These may include:
A multi-parametric MRI scan
You may have this specialised scan to help your doctor decide if you need to have a prostate biopsy. A multi-parametric MRI scan gives a more detailed picture of the prostate gland and surrounding area than a standard MRI scan.
Trans-rectal ultrasound (TRUS) biopsy
You may have a TRUS biopsy if tests show you may have prostate cancer. They use a fine needle to remove samples of prostate tissue to examine for cancer cells. This is done through an ultrasound probe your doctor passes into your back passage. You have an injection of local anaesthetic to numb the area first.
Trans-Perineal (TP) biopsy
You may have a Trans-Perineal biopsy instead of a TRUS biopsy. The doctor takes samples of the prostate gland through the area between the scrotum and the back passage (called the perineum). It can be done under a general anaesthetic or using local anaesthetic to numb the area first.
Further tests after diagnosis
Your doctor may talk to you about having further tests to find out how far the cancer has grown (its stage). You may have some of the following tests:
- an MRI (magnetic resonance imaging) scan which can show if the cancer has spread outside the prostate gland to areas nearby
- a CT scan if you cannot have an MRI scan
- a bone scan to make sure the cancer has not spread to the bones.
Waiting for test results can be a difficult time, we have more information that can help.

Knowing the stage, grade and risk group of the cancer helps you and your doctor to decide on the best treatment for you.
Your doctor decides the grade by how the prostate cancer cells (from your biopsy) look under the microscope. This tells them how quickly the cancer might grow or spread. Doctors use a combination of 2 systems to grade prostate cancer:
- Gleason score - examines the pattern of cells in the prostate tissues and grades them from 1 to 5. The most common and highest grades are added to give your Gleason score
- Grade Group - grades the cancer between 1 and 5 based on your Gleason score.
A team of specialists meet to discuss the best possible treatment for you. This is called a multidisciplinary team (MDT). There are different treatments. Your treatment will depend on:
- your general health
- your age
- the Gleason score, cancer grade
- the stage of the cancer
- the risk group of the cancer
- your preferences.
Your doctor and nurse will talk to you about the different things to think about when making treatment decisions. They will explain the different benefits and disadvantages of each treatment. You and your doctor can then decide on the best treatment for you.
Treatment for early or locally advanced prostate cancer may include one or more of the following:
Radiotherapy uses high energy rays to destroy cancer cells. It can be given from outside the body (external beam radiotherapy) and also from inside the body (brachytherapy). In early prostate cancer sometimes brachytherapy is given as the only treatment.
If you have locally advanced prostate cancer you usually have a combination of external radiotherapy and brachytherapy.
Surgery or radical prostatectomy
- Active surveillance
Active surveillance involves having regular tests to monitor early prostate cancer. It can help to avoid unnecessary treatment or to delay treatment and its side effects.
- Watchful waiting
During watchful waiting, you will not have as many tests as with active surveillance. You see your doctor regularly to check if the cancer is causing symptoms. If you have symptoms or there are signs the cancer is growing you can have treatment, usually with hormonal therapy.
Find out more about monitoring prostate cancer.
- Active surveillance
Prostate cancer needs the hormone testosterone to grow. Hormonal therapies reduce the amount of testosterone in the body. You may have hormonal therapy as tablets or injections. It may be given with radiotherapy and for some time afterwards. Hormonal therapy is sometimes given on its own.
Advanced (metastatic) prostate cancer is usually treated with hormonal therapy and chemotherapy.
You may get anxious between appointments. This is natural. It may help to get support from family, friends or a support organisation.
Macmillan is also here to support you. If you would like to talk, you can:
Sex, relationships and fertility
Prostate cancer treatments can affect your sex life. They can reduce your sex drive (libido) and cause difficulties getting an erection. This is called erectile dysfunction or ED. This may be very worrying for you. There are different treatments and support available to improve sexual difficulties.
Talk to your doctor or nurse about sexual difficulties or concerns. They will be used to talking about these issues. You may want to involve a partner in these discussions.
Prostate cancer treatments can affect your fertility. If this is a concern for you, talk to your doctor or nurse. You may be able to store sperm before treatment starts.
Well-being and recovery
Even if you already have a healthy lifestyle, you may choose to make some positive lifestyle changes after treatment.
Small changes to the way you live such as eating well and keeping active can improve your health and well-being and help your body recover.
