Prostate cancer symptoms, tests and treatment: a clear, kind guide

The short answer

Early prostate cancer often causes no symptoms at all. When signs do appear, they are usually urinary: needing to pee more often, especially at night, a weak flow, or trouble starting. These are far more commonly caused by a harmless enlarged prostate, but they are worth checking with your GP.

In short

• Early prostate cancer often has no symptoms; urinary changes are usually a harmless enlarged prostate, not cancer.
• Prostate cancer is the most common cancer in men in the UK, and it is frequently slow-growing.
• Risk rises with age, family history, and being Black: around 1 in 8 men get it, rising to about 1 in 4 Black men.
• There is no national screening programme, but men over 50 can ask their GP about a PSA blood test.
• The outlook is very good: Cancer Research UK reports most men survive 10 years or more overall.

Prostate cancer is common, and hearing the word is frightening. But it is also one of the more hopeful cancers to read about. Many prostate cancers grow slowly, treatments are effective, and most men diagnosed today do well.

This guide walks through the symptoms, the tests, the choices, and what they mean.

What are the symptoms of prostate cancer?

Signs some men notice include:

• Needing to pee more often, especially during the night
• Difficulty starting to pee, or straining
• A weak or stop-start flow
• A feeling that your bladder has not fully emptied
• A sudden or urgent need to pee
• Blood in the urine or semen, which is less common

These symptoms are usually caused by a benign enlarged prostate, a normal part of getting older, rather than cancer. Because advanced prostate cancer can cause new aches in the back or hips, any unexplained, lasting bone pain is also worth mentioning to your GP.

What is prostate cancer, and how serious is it?

That distinction sits at the centre of prostate cancer care: a lot of it is slow, and "watchful waiting" or active surveillance is a genuine, safe option for low-risk cancers.

A smaller proportion is faster-growing and benefits from earlier treatment. Your team uses the PSA level, scans and a biopsy to judge which kind you have.

What causes prostate cancer, and who is at higher risk?

• Age, with most cases diagnosed in men over 65
• Family history, particularly a father or brother who had prostate cancer
• Being Black, which roughly doubles the lifetime risk
• A family history of certain breast cancer genes, such as BRCA2
• Being overweight, which is linked to more aggressive disease

If you are Black, or your father or brother had prostate cancer, it is worth talking to your GP about your risk from around age 45, a little earlier than the general guidance.

When should I talk to my GP, and what is the PSA test?

It helps to know what the PSA test can and cannot do. A raised PSA can be caused by an enlarged prostate, infection or recent exercise, not only cancer. It can also miss some cancers.

Because of this, there is no national screening programme, but any man over 50 can request the test after a conversation about its pros and cons. Your GP may also offer an examination of the prostate.

How is prostate cancer diagnosed?

• PSA blood test and an examination of the prostate
• MRI scan, now routinely done before any biopsy to guide it
• Biopsy, taking small samples of prostate tissue
• Grading (Gleason score or grade group), showing how aggressive the cancer looks
• Further scans if needed, to check whether it has spread

The grade and the PSA level together shape everything that follows. A low grade with a low PSA often means monitoring is safe, while a higher grade points towards active treatment.

What are the treatments for prostate cancer?

• Active surveillance monitors a low-risk cancer with regular PSA tests and scans, treating only if it changes.
• Surgery removes the prostate, an option for cancer that is still contained.
• Radiotherapy targets the cancer with radiation, sometimes with hormone therapy alongside.
• Hormone therapy lowers testosterone, which prostate cancer needs to grow, and is used for more advanced disease.
• Chemotherapy and newer medicines are used for cancer that has spread.

Treatment can affect urinary control and sexual function, and these effects matter, so a frank talk with your team about the trade-offs is part of a good decision. Support is available for side effects, from your team and from charities such as Macmillan, and you can always get in touch with us if you need pointing to help.

What do the stages of prostate cancer mean?

Even advanced prostate cancer can frequently be controlled for years with hormone therapy and newer medicines. Your team can explain what your particular stage and grade mean, which matters far more than the label on its own.

What is the outlook, and can prostate cancer be cured?

As with any cancer, survival figures describe large groups of men diagnosed in the past and cannot see the newer treatments available now, so they are not a prediction about you. What matters most is your own grade, stage and health, and the plan you make with your team. Many men live long, active lives after a prostate cancer diagnosis, and a good number never need treatment at all.

Can prostate cancer be prevented, and should I get checked?

Our prevention guides cover the wider habits with the strongest evidence behind them. Practical steps that help:

• Know your risk, especially if you are Black or have a family history.
• Talk to your GP about the PSA test from age 50, or 45 if you are higher risk.
• Keep a healthy weight and stay active, which supports overall health.
• Report new urinary or bone symptoms rather than waiting.

No one can guarantee they will never get prostate cancer, and no one is to blame for developing it. But knowing your risk and acting early genuinely helps, which is the whole idea behind our mission.
