We'd like to ask you two questions about our page.

What is recurrent prostate cancer?

Recurrent prostate cancer is when your cancer comes back after you’ve had a treatment that aimed to cure it. It's sometimes called prostate cancer recurrence or prostate cancer relapse.

Treatments that you might have had include:

All these treatments aim to get rid of the prostate cancer. But sometimes not all the cancer is successfully treated, or the cancer may have been more advanced than first thought.

Finding out your cancer has returned

It can be very difficult to learn that your cancer has come back. All the thoughts and feelings you had when you were first diagnosed can come back again and they may be even stronger than before.

It's normal to feel shocked, angry, frustrated, disappointed, worried or sad. All these are very normal ways to feel. Things can get easier over time but some of these feelings may stay with you. Lots of men find it helpful to talk to someone about their feelings. This might be a friend or family member or someone who is trained to listen, like a counsellor or your doctor or nurse. You can also talk to our Specialist Nurses or someone who’s been there through our one-to-one support service or online community.

How do I know if my prostate cancer has come back?

Your doctors and nurses will have monitored you after your first treatment to check for any signs that the cancer has come back.

Usually the first sign that your cancer is starting to return is a continuous rise in the level of prostate specific antigen (PSA) in your blood. The PSA test is a very effective way of checking how successful your treatment has been. The exact change in PSA level that suggests your cancer has come back depends on which treatment you had. Read more about PSA levels after different treatments.

Your doctor may do other tests to check if, and where, your cancer has come back. These may include CT, MRI, and bone scans. Read more about follow-up after treatment for prostate cancer.

What symptoms should I look out for?

If your cancer does come back, the first sign is likely to be a rise in your PSA level, rather than any symptoms.

However, it’s important to let your doctor or nurse know if you do get any new symptoms or side effects, or are worried that your cancer might have come back. Advanced prostate cancer (cancer that has spread from the prostate to other parts of the body) can cause symptoms, such as extreme tiredness (fatigue), bone pain and problems urinating.  Physical problems will often be side effects of treatment rather than a sign that your cancer has come back.

Your doctor or nurse can help find out what might be causing your symptoms and help you manage any side effects. They can also look at your PSA level to see whether or not your cancer might have come back.

Why has my cancer come back?

It’s not always completely clear why prostate cancer comes back, but there are two main possible reasons.

  • Not all of the cancer cells in your prostate were treated during your first treatment. Small clusters of cells might have been left behind. Over time, these may have grown large enough to be picked up by tests or to cause symptoms.
  • The cancer was more advanced than your doctor originally thought. Tests or scans you had when you were diagnosed might have missed small clusters of cancer cells outside your prostate, for example in your lymph nodes or bones (see the diagram below). Your first treatment would not have been aimed at these cells. Over time, the small clusters of cells may have grown large enough to be picked up by tests or to cause symptoms.

When you were diagnosed your doctor would not have been able to tell you whether or not your cancer would come back. But they may have said how likely it was. Read more about your chance of cancer coming back.

Where could my prostate cancer come back?

Your prostate cancer may have come back in one or more areas. It could be:

  • in your prostate, if your prostate hasn’t been removed by surgery
  • in the area around where your prostate used to be (the prostate bed) if the prostate has been removed by surgery
  • in the area just outside your prostate
  • in other parts of your body.

Prostate cancer can spread to any part of the body but it most commonly spreads to the bones and lymph nodes.

Prostate cancer that has spread to other parts of the body is known as advanced prostate cancer.

Sometimes it’s not clear where the cancer is. Some men may have a rise in their PSA level but the cancer may not show up on other tests, at least at first. This is quite common and your doctor will discuss treatment options with you.

What treatments are there for recurrent prostate cancer?

Treatments for recurrent prostate cancer are called second-line (or salvage) treatments. Many of the treatments used to treat prostate cancer when it’s first diagnosed can also be used as second-line treatments.

Making a decision about treatment

Your doctor might offer you one treatment, or a choice of treatments for recurrent prostate cancer. You may also be able to have your cancer monitored rather than treated (see below).

All treatments have advantages, disadvantages and side effects. All men are different and a particular side effect might be a problem for one man but not for another. It’s important to discuss your options with your doctor before deciding on a treatment. You could also talk through your options with your partner, family or friends, or speak to our Specialist Nurses.

What second-line treatments are there?

There are two main types of treatments – those that aim to get rid of the cancer (curative treatments) and those that aim to delay the cancer growing but won’t get rid of it.

Treatments aiming to get rid of the cancer

  • External beam radiotherapy uses high-energy X-ray beams to destroy cancer cells. You might have it with or without hormone therapy.
  • Permanent seed brachytherapy involves implanting tiny radioactive seeds into your prostate.
  • High intensity focused ultrasound (HIFU) uses ultrasound waves to heat and destroy cancer cells in your prostate. HIFU is newer that some other treatments, so isn’t available everywhere.
  • Cryotherapy uses freezing and thawing of your prostate gland to destroy cancer cells. Like HIFU, it's newer than other treatments and so we don't have as much information on how well it works and its possible side effects.
  • Surgery (radical prostatectomy) to remove your prostate and the cancer inside it.

Treatments aiming to control the cancer

  • Hormone therapy works by either lowering the amount of testosterone in the body or by stopping it from reaching the cancer cells, wherever they are in the body. Prostate cancer cells usually need testosterone to grow.
  • Chemotherapy uses anti-cancer drugs to kill cancer cells, wherever they are in the body. You may be offered chemotherapy alongside hormone therapy. It can cause some serious side effects so you will need to be fit enough to cope with these.

Some men who have recurrent prostate cancer decide to take part in clinical trials of new treatments or new combinations of existing treatments. If you are interested in taking part in a clinical trial, ask your doctor if there are any that would be suitable for you.

Monitoring your prostate cancer

You may be able to have your cancer monitored, instead of having second-line treatment straight away. For many men, prostate cancer is slow-growing and may not cause any problems or symptoms, even without treatment. The aim of monitoring is to avoid or delay treatment, and the side effects that treatment can cause.

If you decide to have your prostate cancer monitored, your doctor and nurse will monitor you and your cancer closely for any changes. You will have regular PSA tests. You may also have other tests and scans.

If the tests show that your cancer is growing more quickly than expected, or if you have symptoms, talk to your doctor about starting second-line treatment.

Which second-line treatments are available to me?

It’s unlikely that all of the treatments will be available to you. Several things affect which treatments are suitable, including:

  • where your cancer is
  • your general health
  • your PSA level and other test results
  • what treatment you’ve already had.

What treatment have you already had?

If your first treatment was surgery (radical prostatectomy), you might be able to have:

If your first treatment was radiotherapy, you might be able to have:

If your first treatment was brachytherapy, you might be able to have:

If your first treatment was HIFU (high-intensity focused ultrasound), you might be able to have:

If your first treatment was cryotherapy, you might be able to have:

Speak to your doctor or nurse about which treatments are available to you.

Side effects of second-line treatment

All treatments have side effects. The risk of side effects is usually higher when a treatment is used as a second-line treatment than when it’s used as your first treatment. This is because your first treatment may have already caused some damage to the tissue surrounding the prostate.

Side effects may also be more severe with a second-line treatment. And you might still be getting side effects from your first treatment.

Ask your doctor or nurse for more information about the possible side effects from the second-line treatments they offer you. Read our treatment pages to find out about side effects from different treatments. Finding out about possible side effects might help you to choose between your different treatment options, or whether you want to have any treatment.

What if I don't want further treatment?

Some men weigh up the advantages and disadvantages and decide that they don't want to have second-line treatment for their cancer. Speak to your doctor or nurse if you are thinking about not having further treatment. They may suggest observing your prostate cancer with regular tests. If it starts to cause symptoms then you’re likely to be offered hormone therapy to control the cancer and help relieve symptoms. There are also other treatments to manage symptoms.

What happens after second-line treatment?

You will have regular follow-up appointments to monitor how well your treatment is working. The aim is to:

  • check how your cancer has responded to treatment
  • deal with any side effects of treatment  
  • give you a chance to raise any concerns or ask any questions.

You will have regular PSA tests as part of this follow up. Read more about what to expect from your follow-up care.

What if my cancer comes back again?

If your cancer comes back again after treatment that aimed to get rid of it, you will be offered hormone therapy to control your cancer, though you may not need to start it straight away.

Hormone therapy can keep your cancer under control for many months or years before you need to think about other treatments.

But over time, your cancer may start to grow again. You may continue having your original hormone therapy, but there are also other treatments available. Read more about treatment options after your first hormone therapy.

Some men decide they would like to take part in a clinical trial of a new treatment or a new combination of existing treatments.

What if I develop symptoms?

Tell your doctor or nurse about any symptoms you have. If you have symptoms between your check-ups, tell your doctor or nurse as soon as possible. If these are signs of the cancer coming back, they can talk to you about treatment options.

Your doctor or nurse can also give you advice and treatment to help manage your symptoms. For example, if your cancer has spread to the bones and is causing pain, there are treatments to help, such as pain-relieving medication, drugs called bisphosphonates and pain-relieving radiotherapy.

Dealing with recurrent prostate cancer

A lot of men find it hard if they discover their cancer has come back. All the emotions you had when you were first diagnosed can resurface and they may be even stronger the second time round.

Some men feel angry that their cancer has come back. It is normal to want to find an explanation, but remember it’s not your fault – try to go easy on yourself.

The thought of more treatment can be overwhelming. You may feel less hopeful than you did before. However, men do have successful treatment for recurrent prostate cancer.

You may also have practical concerns about your cancer coming back, for example, worries about work or money.
