Bladder Cancer

Diagnosis and classification

Diagnosis and Classification

Signs and symptoms

Blood in the urine is the most common symptom when a bladder tumour is present. Tumours in the bladder lining (non–muscle-invasive) do not cause bladder pain and usually do not present with lower urinary tract symptoms (urge to urinate, irritation).

If you have urinary tract symptoms such as painful urination or need to urinate more often, a malignant tumour might be suspected, particularly if an infection is ruled out or treated and this does not reduce the symptoms. Muscle-invasive bladder cancer can cause symptoms as it grows into the muscle of the bladder and spreads into the surrounding muscles.

Symptoms like pelvic pain, pain in the flank, weight loss, or the feeling of a mass in the lower abdomen may be present in some cases when tumours are more advanced.
