The tumour affects the prostate, which is a small gland that’s found in the pelvis of men.
It’s not always easy to know if you’re at risk of prostate cancer, as the symptoms tend to develop very slowly over a long period of time.
But, you could reveal your chances of having prostate cancer by checking your urine.
Having a slower urine stream than normal may be caused by the disease, it’s believed.

“Most prostate cancers are found early, through screening,” said the American Cancer Society.
“Early prostate cancer usually causes no symptoms.
“More advanced prostate cancers can sometimes cause symptoms, such as problems urinating, including a slow or weak urinary stream or the need to urinate more often, especially at night.
“Trouble urinating is much more often caused by benign prostatic hyperplasia, a non-cancerous growth of the prostate.”
You could have a higher risk of developing the condition if you’re over 50 years old, or have a family history of prostate cancer.
Obesity may increase your chances of the disease, while there is some evidence that a diet high in calcium could raise your risk.
Around 50,000 new cases of prostate cancer are diagnosed every year in the UK.
But 84 percent of all patients live for at least another 10 years after their initial diagnosis, said Cancer Research UK.
