Because the bladder is responsible for holding urine after it is produced by the kidneys, many symptoms of bladder cancer may relate to urination abnormalities.
Understanding when symptoms are a sign of something serious and either diagnosing bladder cancer or confirming a previous diagnosis require expertise from specialists trained and experienced in treating bladder cancer.
Blood in the urine (hematuria): This is typically the first sign of bladder cancer. It may be present on a regular basis or disappear and reappear over the course of days or weeks. Sometimes blood is present in such a small amount that it can’t be seen with the naked eye, called microscopic hematuria, but a urine test may be able to detect it.
Even a small amount of blood may cause the color of urine to change to orange, pink or, rarely, dark red. When blood causes urine’s color to change, it’s called gross hematuria.
Early-stage bladder cancer doesn't usually cause pain or other symptoms besides bleeding. But blood in the urine doesn't always mean there's a tumor in the bladder. It's more likely to be caused by a less serious condition, such as an infection. kidney stones, bladder stones, or noncancerous tumors or kidney diseases.
It’s also important to note that blood from menstruation may show up in a woman’s urine test, which may cause a false-positive test result. In this case, doctors may recommend repeating the test.
Urination changes: Changes in urination are more commonly a sign of a less serious condition, such as a benign tumor, infection, urinary tract infection, bladder stones, an overactive bladder or, in men, an enlarged prostate. But they also may be another early sign of bladder cancer symptoms. These changes may include:
When bladder tumors grow larger, or cancer cells spread to other areas of the body, they may cause symptoms including:
If bladder cancer has spread, or metastasized, to another part of the body, it may cause symptoms related to that body part.
If bladder cancer is suspected, your doctor may recommend tests to determine the cause of the symptoms.
