If I have bladder cancer, would there be blood in my urine?

Usually. Most patients with bladder cancer will have detectable levels of blood in the urine (hematuria). Sometimes it is visible to the patient while other times it is only seen microscopically. In unusual cases might a person be diagnosed with cancer in the bladder with no hematuria.
Yes. Bladder cancer may cause visible blood in the urine or microscopic blood in the urine which is only picked up by urine tests. Depending on the type of cancer, size, number of lesions, etc, blood may be visible to the naked eye but can also be absent with smaller lesions. Therefore, urine tests must be performed when bladder cancer is suspected.

Blood. Blood in your urine, known as hematuria, can be either gross (visible to the naked eye) or microscopic (invisible to the naked eye, thus found only upon testing or urinalysis). Bladder & kidney infections can cause hematuria. So can kidney stones. However, these three possibilities are typically associated w/discomfort & pain. Painless hematuria is more worrisome for bladder cancer, especially in smokers and those exposed to (carcinogenic) chemicals at work. The diagnosis can be made by your family physician via urine testing, either cytology (looking for cancer cells) or bard bta (looking for tumor antigen). If both of those tests are negative but the reason for the painless hematuria remains elusive, then a cystoscopy (visual examination of your bladder via a small camera inside a tube via your urethra) can be performed by a urologist. Biopsies can be taken at this time to determine the nature and extent of the cancer. Sometimes, other tests will be performed looking to see if there's disease anywhere else. For instance, an intravenous pyelogram will allow us to visualize your kidneys & ureters, in addition to the bladder. An abdominal and/or pelvic ct will allow us to visualize any adjacent structures for spread.
