Bladder cancer is the seventh most common cancer in the UK, according to the NHS.
The disease is caused by abnormal tissue growing in the bladder lining.
The tumour can spread into the surrounding muscles.
Lower back pain could be a sign of bladder cancer.
“If bladder cancer reaches an advanced stage and begins to spread, symptoms can include pelvic pain, bone pain, unintentional weight loss, and swelling of the legs,” said the NHS.
“Blood in your urine is the most common symptom of bladder cancer.
“You may notice streaks of blood in your urine or the blood may turn your urine brown.
“The blood isn’t always noticeable and it may come and go.”
Other bladder cancer symptoms include urinating more frequently, and having sudden urges to pass urine.
A burning sensation when passing urine may also be a sign of the disease.
You should see a GP if you ever find blood in your urine, the NHS recommended.
While the symptom isn’t always a sign of bladder cancer, it’s best to get it checked out.
About 10,000 people are diagnosed with bladder cancer in the UK.
People over 75 years old are most at risk of developing the disease.
Men are also more likely to get bladder cancer than women.
You can lower your risk of the condition by eating a diet high in fruit and vegetables, and low in fat.
