The Silent Killer: Case of Bladder Cancer

Last month actor and Member of Parliament Shri Vinod Khanna died at 70. He was suffering from advanced cancer of the bladder, a balloon-shaped organ that stores urine in the pelvic (Hip) region. The bladder is connected to the kidneys by a tube from each kidney called a ureter. When the bladder reaches its capacity of urine, the bladder wall contracts, although adults have voluntary control over the timing of this contraction. At the same time, a urinary control muscle in the urethra relaxes. The urine is then expelled from the bladder. The urine flows through a narrow tube called the urethra and leaves the body through urination.

Bladder cancer is one of the most common urological malignancies. It is the fourth most common cancer in men and eighth most common malignancy in women of the western world. As per the Indian cancer registry, Bladder cancer constitutes the ninth most common malignancy and accounts for an overall 3.9% of all cancer cases. It is seen more in men than the women. It is rarely seen in people below the age of 40 and affects the elderly more.

The symptoms include painless blood in the urine or frequent and painful urination, unexplained pain in back or pelvis area. Tobacco smoking is the main known contributor to urinary bladder cancer and nearly half of all the cases are due to it. When you smoke, your body processes the chemicals in the smoke and excretes some of them in your urine. These harmful chemicals may damage the lining of your bladder, increasing your risk of cancer.

The other known causes are exposure to chemicals such as arsenic or those used in the manufacture of dyes, rubber, leather, textiles and paint products. People employed as bus drivers, rubber workers, motor mechanics, leather workers, blacksmiths, machine setters and mechanics are at increased risk due to the chemical exposure. People having received radiation aimed at the pelvis for a previous cancer run an increased risk. People who are obese, with chronic or repeated urinary infections or inflammations also have an increased risk.

Bladder cancer can be treated normally through surgery, chemotherapy or radiation. The type of treatment performed depends on a variety of factors including the stage at which the cancer is detected, age, life span, likelihood of the treatment working and the patient itself. Sometimes, a radical cystectomy is performed, in which the entire bladder is removed. Bladder cancer can be prevented by quitting smoking as it is a common cause for it. Avoid exposure to arsenic and industrial chemicals can also prevent the onset of the disease. Last, eating healthy foods and staying hydrated can prevent bladder diseases.

    Thank you Doctro for the article. have a question, my father's creatinine goes up and down.

    like, 6 months ago, he had some pain in his leg, his truned reddish with swelling, doctoers did surgery and removed the puss inside it, during this surgery his creatinnine went up to 7.5 and then doctor put the cathetor (he had problem with his prostate earlier i.,e freequent urinating in the night middle of the sleep)

    since that operation the Creatinine going up and coming down. does this indicate anything about prostate cancer ? he did biopsy during surgery but did not find prostate to be cancerous.
