Exercise and prostate cancer: what the evidence says

Yes, exercise helps men with prostate cancer. NICE recommends supervised resistance and aerobic exercise for men on hormone therapy [4][20], and trials show it reduces fatigue, protects muscle and improves quality of life [6][7]. Whether it prevents the disease or slows its growth is less certain.

Can exercise help prostate cancer?

The strongest evidence is for how you feel and function during and after treatment. A systematic review of 16 randomised trials (1,574 men, all stages of prostate cancer) found exercise improved cancer-specific fatigue, fitness and lower-body strength, and improved quality of life in the higher-quality studies [7].

The same review found no exercise-related deaths [7]. ACSM (2019) and ASCO (2022) agree: exercise is generally safe for people with cancer, every survivor should avoid inactivity, and aerobic plus resistance training should be encouraged during treatment [9][10].

Prostate Cancer UK suggests being active at least two to three times a week, working towards 30 minutes of moderate exercise on three to five days a week [1]. For the wider picture, see our guide to exercise and cancer.

Does exercise slow prostate cancer or improve survival?

This is where the evidence is promising but not proven. In a US study that followed 2,705 men diagnosed with non-metastatic prostate cancer, those doing three or more hours a week of vigorous activity had a 61% lower risk of dying from prostate cancer and a 49% lower risk of dying from any cause. Walking for 90 minutes or more a week at a normal to brisk pace was linked to a 46% lower risk of death from any cause [5].

That study is observational: it shows an association, not cause and effect. The randomised trials reviewed by Bourke and colleagues found no evidence that exercise changes disease progression [7]. So exercise may improve survival, but that has not yet been proven in a trial.

Hard exercise and cycling can raise your PSA. The NHS advises not doing anything that leaves you out of breath, such as exercise or riding a bike, for 48 hours before a PSA test, because it can make the result less accurate [18]. Follow your clinic's instructions.

Can exercise prevent prostate cancer?

There is no strong evidence that exercise on its own prevents prostate cancer. Cancer Research UK lists age, family history and ethnicity (it is more common in Black men) as the established risk factors, and does not list inactivity among them [11].

Weight has the most support: Cancer Research UK says being overweight or obese "may be linked to a higher risk of metastatic prostate cancer", while noting more research is needed [11]. Being active helps you manage your weight, so it plays an indirect role.

Can exercise cause prostate cancer?

No. There is no evidence that exercise of any intensity causes prostate cancer, and it does not appear in Cancer Research UK's list of risk factors [11]. In the randomised trials, serious side effects were no more common in men who exercised than in men who did not [7], and every clinical guideline recommends staying active [4][9][10].

Exercise on hormone therapy: managing ADT side effects

Hormone therapy (androgen deprivation therapy, or ADT) lowers testosterone. Prostate Cancer UK lists its common side effects as hot flushes, extreme tiredness, weight gain around the waist, loss of muscle and strength, "brain fog", bone thinning, and an increased risk of heart disease, stroke and type 2 diabetes [2]. Exercise has the best evidence for several of these.

In a randomised trial, 57 men on hormone therapy did 12 weeks of combined resistance and aerobic exercise or usual care. The exercise group gained lean muscle, got stronger, walked faster and reported less fatigue. No adverse events occurred [6].

This is why NICE's prostate cancer guideline (NG131) recommends supervised resistance and aerobic exercise for men on hormone therapy. A UK trial that built this into NHS care describes the recommendation as 12 weeks of combined exercise, done twice a week [4][20]. If your hospital has not offered this, ask.

Some free programmes are aimed at men on hormone therapy. PureGym, working with The Institute of Cancer Research and The Royal Marsden, offers men with locally advanced or metastatic prostate cancer who are on hormone therapy a free year's membership and a 26-week programme of home and gym videos [13]. Nuffield Health's Cancer Activity Programme is "a free, 24-week supervised exercise programme" for people having hormone therapy as part of prostate cancer treatment [14]. Check with each provider whether you are eligible and where it runs. Our guide to cancer exercise programmes covers other options.

Weight gain and diabetes risk matter too. Prostate Cancer UK says physical activity and a healthy diet can help you stay a healthy weight, and that if you are finding it difficult to lose weight you can ask your doctor to refer you to a dietitian or weight loss programme [2]. See nutrition during cancer treatment.

Best exercise for prostate cancer

The programmes that worked in the trials combined two things:

• Resistance (strength) training – weights, resistance bands or body-weight exercises. This is what protects muscle and strength on hormone therapy [2][6].
• Aerobic exercise – walking, cycling or swimming at a moderate pace: your heart beats faster but you can still talk, about the level of a brisk walk [1].

Prostate Cancer UK names walking, swimming, cycling and gardening as good options, and says gentle resistance exercise "is particularly good if you're on hormone therapy and are at risk of bone thinning" [1]; our osteoporosis exercise guide covers bone-safe training. If you are doing nothing, a short daily walk is the right first step.

Pelvic floor exercises after prostate surgery

Urine leakage is common after radical prostatectomy, and pelvic floor muscle exercises (Kegel exercises) are the first-line way to regain control. Prostate Cancer UK advises starting them four to six weeks before surgery, which might help you stop leaking sooner [3]. Our prehabilitation guide explains what else helps before surgery.

Key points from Prostate Cancer UK's guidance [3]:

• Do not do pelvic floor exercises while you have a catheter in.
• Start as soon as the catheter has been removed; the exercises are safe.
• Do a mix of slow contractions (held for up to 10 seconds) and fast contractions (1 second each), up to 10 of each, three times a day.
• It can take up to three months before you notice a real difference.

If you are still leaking or unsure of your technique, ask your medical team about a continence advisor or men's health physiotherapist [3]. A physiotherapist, not an exercise physiologist, is the right professional for pelvic floor assessment.

Exercise if prostate cancer has spread to the bones

Bone metastases are not a reason to stop exercising, but they are a reason to be supervised. In a randomised trial of 57 men (average age 70) with prostate cancer that had spread to the pelvis, spine, ribs or other bones, three months of supervised aerobic, resistance and flexibility exercise three times a week improved physical function and lower-body strength. There were no exercise-related adverse events or fractures, and bone pain was no worse than in the usual-care group [8].

Prostate Cancer UK's advice is clear: if you are on hormone therapy or have cancer in the bones, check with your doctor before doing high-impact exercise such as running or contact sports [1].

Most men in that trial had cancer in the pelvis or spine [8], so two further cautions matter. Avoid repeated forward bending at the waist, such as sit-ups and toe-touching [17], and movements that twist the spine, such as yoga-style twists, the rowing machine, and golf or tennis swings [21]. Ask your team to agree a programme built around which bones are affected. Our guide to exercise with other cancers covers bone metastases in more detail.

Who should you see?

For a supervised strength and aerobic programme on hormone therapy, or if your cancer has spread to the bones, a clinical exercise physiologist (CEP) can assess you and build the programme around your treatment. NHS Health Careers lists oncology among the areas CEPs work in, and CEPs from accredited courses can join a voluntary register run by the Academy for Healthcare Science [16]. Your specialist nurse can tell you what your hospital offers.

When to be cautious / talk to your doctor first

Speak to your doctor or specialist nurse before starting or stepping up exercise if:

• your cancer has spread to the bones, or you have new or worsening bone pain [1][8]
• you are on hormone therapy and have not exercised for a long time [1]
• you have heart disease, or hormone therapy has raised your cardiovascular risk [2]
• you have a catheter in place (no pelvic floor exercises until it is out) [3]
• you have had recent surgery and have not been told when you can lift or exercise again
• you have swelling in a leg, your genitals or lower tummy: prostate cancer and its treatment can cause lymphoedema [15] (see lymphoedema and exercise)

Macmillan says you should stop exercising if you get any sudden symptoms, such as chest pain, feeling dizzy, a racing heart, breathing problems or unusual back or bone pain, and speak to a doctor straight away [17].

If your cancer has spread to the bones, know the signs of spinal cord compression: back or neck pain that may be mild at first but becomes severe, weakness in your arms or legs, numbness or pins and needles, or problems controlling your bladder or bowels [12]. This needs urgent medical attention [19]. Contact your specialist nurse straight away. Out of hours, call your hospital's oncology emergency contact number or your out-of-hours GP, or go to A&E [19].
