One in eight men in the UK will get prostate cancer - but the earlier you spot it, the easier it is to treat.
However, many of the symptoms of prostate cancer are the same as those caused by several less serious conditions. Here we look at the signs to look out for and when to speak to your doctors.

Cancer de la prostate is the most common cancer in men in the UK, but many of its symptoms are also signs of less serious problems. Men's health specialist Dr Jeff Foster, a GP at H3Health, explains that in the early stages of prostate cancer, it's especially difficult to tell the difference between prostate cancer and benign prostatic hyperplasia (BPH), also called l'hypertrophie de la prostate.
While prostate cancer can be life-threatening, BPH is a treatable prostate disease that doesn't lead to cancer. Although prostate cancer is much more serious, the doctor explains that the same principle applies to the two conditions:
"In both cases, something in the prostate gland - which helps produce semen - gets larger and squashes the tube through which you pee (urethra), which causes problems while peeing. This is the principle of every prostate disease, and it means that they each have many of the same symptoms."
Here is an overview of each condition:
An enlarged prostate - it's usual for a man's prostate to grow with age, which tends to decrease your urine flow and range over time. This isn't a problem or sign of poor health.
BPH - this is when your prostate gets large enough to squeeze the urethra, causing issues. What's usually the size of a walnut or golf ball in adult men, may become as large as an orange.
Cancer de la prostate - also involves the prostate getting bigger. However, this is caused by an abnormal growth of cancerous cells that can spread to other parts of the body. It's this spread that poses a serious risk to your health.

What are the early symptoms of prostate cancer?
Problems when you pee
Early stage prostate cancer symptoms are caused by the extra pressure placed on your urethra. As BPH and other prostate problems can also squeeze this tube, the following symptoms could be a sign of any of them. The only way to know for sure is to get checked out by your doctor.
Incontinence urinaire
Having incontinence urinaire means you cannot always control when you pee, and you may regularly leak and dribble. It could also mean that you have urgency incontinence, where you feel a very sudden and intense urge to pee and only have a few seconds to get to a toilet before pee from your bladder is released.
Needing to pee more frequently
Problems with peeing and needing to pee more frequently can become a constant disruption in your life. Night-time is one of the most obvious times you may notice an increase. According to Dr Foster, it's common for people with prostate problems to visit the toilet three or four times a night.
Difficulty peeing
Although your number of toilet trips may go up, once you're in front of the bowl you may find peeing difficult. For example, you may find it hard to release pee, notice that your flow has become much weaker, or frequently find that your bladder doesn't feel empty after peeing.
The speed of symptoms
You'll need to see a doctor to test if the symptoms mentioned indicate prostate cancer or something else. Dr Foster says you should take notice of how quickly these symptoms develop. If they come on suddenly, and quickly become more severe, this is one possible indicator that your urinary problems could be cancerous. Other benign prostate conditions like BPH will develop much more gradually.
What are the symptoms of advanced prostate cancer?
Retour au sommaireAdvanced prostate cancer - also called metastatic prostate cancer - means the cancer has spread beyond your prostate gland. As the cancer begins to affect your lymph nodes and other parts of your body, you may notice other symptoms.
You have a better chance of recovering from prostate cancer the earlier it's caught, so if you experience any of the following advanced prostate cancer symptoms listed, you should see your doctor as soon as possible, especially if you also have problems when you pee.
These signs can also be caused by other, less serious issues - but don't self-diagnose, the tests performed by your doctor are the only way to know for sure.
Finding blood in pee or semen
Prostate cancer is one possible explanation for finding blood in your pee (haematuria) or in your semen (haematospermia). However, there are several conditions that could cause this, including infections des voies urinaires (IVU) and other enlarged prostate problems such as prostatite.
Feeling pain in your pelvis, hips, or back
Advanced prostate cancer may spread to your bones, known as bone metastasis, and as a result, your bones may become painful. You're more likely to feel this in your back, pelvis, and hip bones, due to their close proximity to your prostate, which sits just beneath your bladder.
Dysfonction érectile
Dysfonction érectile means you repeatedly find it difficult to get or keep an erection. This has several possible causes, ranging from physical health issues, such as hormone changes, to mental health issues - such as l'anxiété et dépression.
Erectile dysfunction affects around 4 out of 10 men at age 40 and around 7 out of 10 at age 70, and as a symptom on its own it's unlikely to be a sign of prostate cancer. However, it can be seen as a symptom in advanced prostate cancer but other symptoms would usually be present too.
Unexplained weight loss
Perte de poids involontaire isn't usually one of the first prostate cancer symptoms people notice. However, if you find you've lost weight without any changes in your lifestyle, and you're experiencing any other symptoms previously listed, it's worth getting tested. Weight loss tends to be a sign of advanced prostate cancer, due in part to the increased activity of cancer cells in the body - the more cancer cells there are, the more energy they use up.
