Early prostate cancer symptoms an oncologist says men over 40 should never ignore

 A leading cancer specialist has highlighted the key prostate cancer symptoms men should be aware of to help catch the disease early. According to Prostate Cancer UK, prostate cancer is the most commonly diagnosed cancer in men, with around one in eight diagnosed during their lifetime, making awareness of easily missed symptoms particularly important.

Dr Jiri Kubes, radiation oncologist and medical director at the Proton Therapy Center in Prague, explains that men over 40 should pay close attention to subtle changes they might otherwise dismiss.

Prostate Cancer Symptoms Men Over 40 Need to Be Aware Of

1. Needing to Urinate More Often, Especially at Night

One of the earliest warning signs is a change in urination patterns. ‘Men may find themselves getting up multiple times in the night or needing to go far more frequently during the day,’ Dr Kubes says. ‘This happens because an enlarging prostate can press on the urethra. While this is often blamed on ageing or an enlarged prostate, persistent change should always be checked.’

2. Difficulty Starting or Stopping Urination

‘Struggling to start urinating or having a weak, interrupted stream is another common sign,’ he explains. ‘Men often ignore this, assuming it’s a normal part of getting older, but obstruction caused by prostate changes can be an early indicator that something more serious is happening.’

3. A Feeling That the Bladder Never Fully Empties

‘Many men describe finishing in the bathroom but feeling like they still need to go,’ Dr Kubes says. ‘This sensation can be subtle but persistent. It’s caused by pressure from the prostate affecting how the bladder drains and it’s a symptom that should not be overlooked.’

4. Blood in Urine or Semen

‘Blood is never normal,’ Dr Kubes warns. ‘Even a small amount of blood in urine or semen warrants immediate medical attention. While there can be benign causes, it is a red-flag symptom that must be investigated promptly.’

5. Erectile Difficulties or Painful Ejaculation

‘Prostate changes can also affect the surrounding nerves and tissues,’ he says. ‘Men may notice new erectile issues or discomfort during ejaculation. These symptoms are often embarrassing to talk about, which can delay seeking help.’
