A recent research revealed that blood in the urine could be an early sign of prostate cancer.
According to Express.co.uk., blood that is clearly visible in the urine is known as gross hematuria, and it can turn to pink, red or cola-colour.
If people notice blood in their urine, they should immediately see a doctor, the research said. However, it doesn't necessarily mean you'll be diagnosed with prostate cancer.
Other signs of prostate cancer include taking long time to urinate or having a weak flow.
People could also feel the urge to urinate more often, or get a feeling like the bladder is not fully empty when you finish urinating.
Difficulty getting or maintaining an erection could also be a sign of prostate cancer, of which 40,000 new cases are diagnosed in the UK every year.

The cause of prostate cancer is largely unknown. But, the risk of developing the disease increases as humans get older.
Prostate cancer develops very slowly, and people can live without symptoms or treatment for decades.
The cancer could be removed through surgery, and it could be treated by radiotherapy, or hormone therapy.
