This symptom makes up one of the three main warning signs of prostate cancer in men which also includes needing to pee more and straining to start your flow.
Prostate cancer is the most common male cancer and affects around one in eight men during their lifetime.
Recent figures show there are around 55,000 diagnoses in the UK every year – that’s around 150 every day according to the charity Prostate Cancer UK.
But detecting issues as early as possible can go a long way to ensuring positive outcomes and experts are advising men – particularly those over 40 – to be aware of any changes in their toilet habits to give themselves the best chance.
Leading oncologist Dr Jiri Kubes insists this can provide a potentially life-saving early warning that there could be something wrong.
He said: “As with any change in your body, you should keep a close eye on it and seek advice from your GP as soon as possible.
“In some cases there will be nothing to worry about, but it is vital to consult with an expert if you have any doubts whatsoever.
“The main warning signs you are likely to experience when going to the toilet are an increased need to urinate, during the day and night, a slow or interrupted flow and a feeling of still needing to urinate even when you have finished.
“It may be more difficult to start your flow and there could even be traces of blood in your urine.
“Sometimes those with prostate cancer will also experience discomfort when sitting down.”
According to the NHS website: “Prostate cancer does not usually cause any symptoms until the cancer has grown large enough to put pressure on the tube that carries urine from the bladder out of the penis (urethra).”
This is when the warning signs start to show themselves, which should prompt rapid action by contacting your doctor.
Prostate cancer can be difficult to detect in the early stages. One method is by taking a PSA test, which measures the level of prostate-specific antigen in the blood.
But while these straightforward tests, which can be carried out at your local surgery, are able to detect prostate cancer at a very early stage, they are not always accurate.
Treatment options for prostate cancer include radiotherapy, hormonal therapy and surgery, also known as a radical prostatectomy where the entire prostate is removed.
An increasingly popular alternative is proton therapy, where a ‘pencil beam’ of positively-charged particles – travelling at 100,000 miles per hour – targets the area with pin-point accuracy.
It is said to have a better chance of shrinking the tumour and unlike traditional radiotherapy, which passes X-rays all the waay through the body, proton beam therapy particles stop at the tumour, therefore reducing collateral damage and secondary cancers.
Dr Kubes, senior physician at the Proton Therapy Center in Prague which has treated thousands of prostate cancer patients since opening in 2012, says the pencil beam treatment can successfully cure up to 97 per cent of prostate cancer patients.
He adds: “The advantages of proton beam therapy include a reduced risk of erectile dysfunction – with 94% of men reporting they remain sexually active – plus shorter recovery times.
“The risk of incontinence following proton therapy treatment is 1%, compared to 15% of patients after surgery and 5% following conventional radiation therapy.”
The NHS has its own proton therapy treatment centres at The Christie hospital in Manchester and University College London. But prostate cancer patients are not routinely treated at the facilities.
