Bladder Cancer Information

  • Bladder cancer refers to any of several types of malignant growths of the urinary bladder. It is a disease in which abnormal cells multiply without control in the bladder. The bladder is a hollow, muscular organ that stores urine; it is located in the lower abdomen. The most common type of bladder cancer begins in cells lining the inside of the bladder (epithelial cells) and is called transitional cell carcinoma (TCC)...
  • The greatest risk factor for bladder cancer is a genetic predisposition; it is also associated with smoking and occupational exposure to aniline-based dyes (such as in textile factories), as well as with petrol and other chemicals.

    Bladder cancer may cause blood in the urine, pain during urination, frequent urination, or feeling the need to urinate without results. These signs and symptoms are not specific to bladder cancer, and are also caused by noncancerous conditions, including prostate infections and cystitis.

    The treatment of bladder cancer depends on how deep the tumor invades into the bladder wall. Superficial tumors (those not entering the muscle layer) can be "shaved off" using an electrocautery device attached to a cystoscope. Immunotherapy in the form of BCG instillation is also used to treat and prevent the recurrance of superficial tumors. BCG immunotherapy is effective in up to 2/3 of the cases at this stage. Instillations of chemotherapy into the bladder can also be used to treat superficial disease.

    Untreated, superficial tumors may gradually begin to infiltrate the muscular wall of the bladder. Tumors that infiltrate the bladder require more radical surgery where part or all of the bladder is removed (a cystectomy) and the urinary stream is diverted. In some cases, skilled surgeons can create a substitute bladder (a neobladder) from a segment of intestinal tissue, but this largely depends upon patient preference, renal function, and the site of the disease.

    A combination of radiation and chemotherapy can also be used to treat invasive disease, and, in many cases, it is not yet known which is the better treatment - radiotherapy or radical ablative surgery.

    In the United States, bladder cancer is the fourth most common type of cancer in men and the ninth most common cancer in women. More than 47,000 men and 16,000 women are diagnosed with bladder cancer each year.

I think I have done a fairly decent job of keeping myself and my family healthy...we eat organic when possible, stay away from products made with PBAs, use paint in the house with low HOVs, use salt water to kill the weeds in our driveway instead of roundup...but who thought I had to micromanage the shirt I just bought? Or the jeans I buy for my ... Read More »
1. It’s complicated: The bladder has two functions that are totally opposite of the other. One is to relax and stretch out so it can store urine (and fill like a balloon,) and the other is to contract and squeeze down so that it can empty the urine. 2. It requires communication: The bladder, spinal cord, brain, and nerves need ... Read More »
Whether its knee replacement, lumbar spine surgery, or hysterectomy; most of the anxiety my patients have about their upcoming surgery is about pain they will have after surgery, and potential nausea and vomiting from their pain meds. Patient controlled analgesia (PCA) is often used after surgery where patients press a button to deliver their ... Read More »
