Bladder Cancer

Notice: See blood in your urine, see your Doctor

For selected points from bladder cancer textbook of Dr. Kaviani and co-authors, look at the middle of left column.

Bladder cancer is the fourth most common cancer diagnosed in men. Cancer that is only in the lining is called superficial (non-muscle invasive) bladder cancer. If the cancer spreads into the muscle wall of the bladder, it is called muscle invasive bladder cancer. In about half of all cases, patients are first diagnosed with superficial bladder cancer. In the remaining cases, patients have muscle invasive bladder cancer. Rarely (in about 4% of cases), it has spread to distant sites.

  • The most common presenting symptom of bladder cancer is painless blood in the urine
  • The most common cause of visible blood in urine in a patient older than age 50 years is bladder cancer.
  • Some patients just have irritative urinary symptoms. It means they need to go to the bathroom several times during  the days as well as the nights.Patients might have some urgency to urinate. Although these symptoms might be due to other more common conditions, an appropriate evaluation for the bladder cancer like performing urine cytology should be done.

Selected tips from Bladder Cancer textbook:

  • Blood in urine, particularly in the adults, should be regarded as a symptom of malignancy until proved otherwise. Even if the patient has another reason for the presence of this blood in his or her urine, we still would like to evaluate for more serious problems, because we do not want to miss any cancers in any patient.
  • Not every person with blood in his or her urine has a bladder cancer. Several different things can cause this problem. However, due to significance of this issue, we need to evaluate for that.
  • All patients with blood in urine, except perhaps young women with acute bladder infection, should undergo a urological evaluation.
  • Even presence of blood in urine test in a person who does not see any blood in his urine needs complete evaluation.
  • Presence of blood in urine is often quite intermittent.So a negative result on the next urine test has little significance in ruling out the presence of bladder cancer.
  • Complete urological evaluation in these patients consists of at least a Cystoscopy, Urine Cytology and Spiral CT scan of urinary tract with injection of intravenous dye.
Urinary Badder:

The urinary bladder is a hollow muscular organ that collects  urine excreted by the kidneys . It sits at the bottom of your abdomen and on your pelvic floor.

Bladder Lining:

As we said in other parts of this page, bladder cancer usually originates from the inner lining of urinary bladder. This layer is call Transitional Epithelium. So, the most common cause of badder cancer is called Transitional Cell Carcinoma. 

Transitional Cell Carcinoma:

Bladder cancer begins most often in the cells that line the inside of the bladder. Bladder cancer usually affects older adults, however it can also affect younger ones too.

by Walid MS, Heaton RL

Bladder Cancer Staging:

Transitional Cell Carcinoma of Bladder usually starts in inner lining of bladder called mucosa. However, it can grow deeper and involves bladder muscle and even other organs that lie close to the bladder.
