The most common symptoms of bladder cancer are: 

• blood in the urine (haematuria) or a sudden change ^[21] in urine colour – slightly rusty to bright red ^[22]
• feeling the need to urinate immediately or passing urine frequently  
• pain or a burning feeling during urination 
• loss of appetite and weight loss 
• pain in the pelvis, lower abdomen or lower back – this is less common ^[23]. 

Many conditions can cause these symptoms, not just bladder cancer. If you have any of these symptoms, it is important that they are discussed with a doctor. Blood in the urine should never be ignored.
