Bladder cancer is the rapid, uncontrolled, and abnormal growth of the cells of the walls of the urinary bladder. It stands in ninth place among the other types of cancers in the world. Bladder cancer can be either non-invasive (i.e. restricted to only the inner lining of the bladder) or invasive (i.e. which spreads to the inner walls of the bladder) or advanced bladder cancer (which has spread to the other body parts).
Bladder cancer is caused due to changes in the cells of the bladder which occurs most often with chemical exposure. Mutations in the DNA of the cells can change the growth and division cycle thereby causing an uncontrolled mass of tumor cells.
The most common symptoms of bladder cancer include:
If bladder cancer reaches advanced stages, then you may have pelvic pain, swelling of legs, bone pain, and an unintentional weight loss.
If you have the above symptoms, it does not necessarily mean that you have bladder cancer. However, it is important for you to get evaluated by a general physician (GP) because it is possible to cure cancer when it is in the early stage.
The following conditions increase your risk of getting bladder cancer:
Tobacco: The biggest risk factor for bladder cancer is smoking. Nearly 1 in 3 cases of bladder cancer is due to smoking.
Chemicals: Exposure to certain chemicals are found to be the cause of bladder cancer in nearly 25% of the reported cases. Examples of such chemicals are dyes, paints, rubber, plastic, leather tanning, etc.
Age: As you age, your risk for bladder cancer increases. The risk is high in people aged above 40 years.
History of other cancer: If you have been treated for other types of cancers either with radiations to the pelvis or chemotherapy drugs, then your risk for bladder cancer increases.
Either due to the condition or due to the treatment, certain complications can occur in the patient, impacting daily life.
Emotional disruption: The patient may have a feeling of sadness with the diagnosis of bladder cancer and may not enjoy anything. In severe cases, it can also lead to depression.
Sexual problems: Problems such as erectile dysfunction (with radical cystectomy) or narrowing of the vagina (with radiotherapy and cystectomy) are possible.
Infections: If you have undergone surgical procedures for your bladder cancer treatment, then you are more likely to get infected.
Contact your physician if you are experiencing any of the above complications as they are treatable.
Your doctor asks about your symptoms, family history, medical history, and if you have been exposed to specific chemicals, to get an initial clue regarding the condition.
A urine sample is collected to test for the presence of blood, abnormal cells or bacteria. Physical examination of your rectum and vagina are performed to check for the presence of lumps of bladder cancer that press the organs. Further tests, as mentioned below will be performed if bladder cancer is suspected:
|Test type||Purpose of the test|
|Cystoscopy||To examine the inside of your urinary bladder through the images produced by the cystoscope|
|CT scan and MRI||Performed if a more detailed image of the bladder is required|
|Urogram||To get the whole picture of your urinary system|
Treatment is based on the stage and grade of cancer.
Superficial tumors of lower grade (non-invasive) cancers are treated through transurethral resection of the bladder tumor (TURBT) followed by a dose of chemotherapy (which is optional) to reduce recurrence. Here, only the tumor is surgically removed through the urethra leaving the bladder intact.
If the stage is of higher grade and has high chances of recurrence, then Bacillus Calmette-Guérin (BCG) medication is injected into the bladder. This type of invasive cancer is removed surgically by removing the bladder completely by the procedure called cystectomy. As the bladder is removed, other operations for collecting urine are performed simultaneously. If surgery is not advisable, then chemotherapy and radiotherapy are recommended.
You may take certain precautionary steps to help your treatment.
Avoid saturated fats (ghee, butter, hard cheese, cakes, etc.) while including unsaturated fats (fish liver oil, nuts, avocados, vegetable oils, etc.)
