Symptoms of bladder cancer include blood in the urine, painful urination, frequent need to urinate, pelvic pain and back pain, according to Mayo Clinic. Patients who experience symptoms should make an appointment with a health care professional for proper diagnosis.
Blood in the urine is often the earliest sign of bladder cancer, as stated by the American Cancer Society. Urine may be pink, orange or red depending on the amount of blood present, but smaller amounts of blood may only be detected during a urinalysis. In the earliest stages of cancer, patients often experience no other symptoms, and blood may only appear in the urine intermittently, with weeks or months between occurrences. More common causes of blood in the urine include benign tumors, infections, kidney stones, bladder stones and kidney disease.
Changes in urination that may signal bladder cancer include the need to urinate even when the bladder is not full and a burning sensation during urination, as confirmed by the American Cancer Society. More common causes of these changes include bladder stones, infections and an enlarged prostate. In its more advanced stages, bladder cancer may cause loss of appetite, the inability to urinate, bone pain, swelling of the feet and pain in the lower back that affects one side of the body.
