Bladder cancer is a common mutation that begins in the urothelial cells that line the inside of the bladder. The cancerous cells are also found in the kidneys and the ureters. The condition is usually diagnosed at an early stage and is also treatable. However, bladder cancer may replase after it is eliminated or in remission. In either case, one should be mindful of its signs so that one can get on a treatment plan immediately. Pain in the lower back One may experience pain in the lower back or abdomen for multiple reasons, including an injury. But if the pain occurs with other symptoms, such as those associated with urination, they might need to speak to an expert to determine its cause, which could be bladder cancer. Those who develop this sign may experience pain, usually on only one side of the body. Unusual bladder changes The presence of cancerous cells in the bladder may result in multiple unusual bladder symptoms. One may start urinating more often than usual, wake up many times at night to urinate, or experience pain or a burning sensation during urination. The individual may also have trouble urinating or have a weak urine stream. Other symptoms include the urge to empty the bladder immediately, even if it isn't full. Blood in the urine One of the early warning signs of bladder cancer is blood in the urine. There might be ample blood to make the waste liquid look pink, orange, or dark red. Sometimes, the color of urine might be normal, but a test may still find traces of blood during a diagnosis. The symptom isn't always associated with cancer, but one should see an expert if one notices the symptom. Persistent bladder infections Another common symptom that one may have is a bladder infection. While these infections could occur due to other health complications, the sign might be persistent if it is caused by cancer. Therefore, it may heal even after treatment with the usual antibiotics. In such cases, one should speak to an expert about potential signs of bladder cancer. A sudden drop in BMI An individual may experience a drop in pounds when they indulge in strenuous exercises or are affected by an infection. It may also be a side effect of ongoing treatments for health conditions. However, if one experiences a loss of more than three pounds in a week, and out of the ordinary, one should speak to an expert immediately. The sign could be an indication of the onset of bladder cancer. Pain in the bones The painful sensation from cancer developing in the bones may range from mild to severe. If one notices this unusual development, one must speak to a healthcare professional.
