Bladder Cancer: What You Need to Know

Do you know that bladder cancer is the 10th most common cancer worldwide?

In 2022 alone, more than 600,000 people globally received this diagnosis, and tragically, over 220,000 lives were lost to this disease.

However, a bladder cancer diagnosis doesn't have to be a life sentence.

With early medical intervention, you can always overcome this challenge and reclaim your health and well-being. In this blog post, we'll comprehensively explore the facts about bladder cancer.

Whether you're a patient, caregiver, or simply want to be an informed advocate, this guide will equip you with vital knowledge about confronting and conquering this formidable disease.

What is Bladder Cancer?

Bladder cancer is a cancer that begins in the bladder - the hollow, muscular organ located in the pelvic region that stores urine.

This disease arises when the cells lining the bladder undergo abnormal and uncontrolled growth, resulting in tumors.

Types of Bladder Cancer

Bladder cancer can be categorized in two ways:

1. Type of Bladder Lining Cell where the Cancer Starts

The general term for cancer in this group is carcinoma, the cancer in epithelial tissues. Epithelial tissue lines most organs' internal surfaces and passageways, including the bladder.

There are 5 types of bladder carcinomas:

a) Urothelial Carcinoma (Transitional Cell Carcinoma)

Urothelial cells are also known as transitional cells. These cells can stretch when the bladder fills with urine and shrink as it empties.

This carcinoma is the most common form, accounting for around 90% of bladder cancer cases.

Typically, urothelial carcinoma begins in the inner bladder lining and can spread to the deeper layers of the bladder wall and the fatty tissues surrounding the bladder.

b) Squamous Cell Carcinoma

Squamous cells are thin, flat cells lining the inside of the bladder.

Around 5% of bladder cancers are squamous cell carcinomas. It often arises from long-term inflammation or irritation of the bladder.

c) Adenocarcinoma

Adenocarcinoma, which accounts for 1-2% of all bladder cancers, originates in the glands within the bladder lining that produce mucus.

d) Small Cell Carcinoma

This rare form of bladder cancer, representing less than 1% of cases, begins in the neuroendocrine cells of the bladder.

These cells release hormones into the bloodstream in response to signals from the nervous system.

2. Muscle Invasiveness of the Tumors at the Bladder

Bladder cancers are also categorized based on how deeply the tumor has invaded the layers of the bladder wall.

Here are the 3 main types:

a) Noninvasive

This early stage refers to tumors that are still confined to a small section of the innermost tissue lining or present only on the surface of the bladder.

The tumor has not yet penetrated the deeper layers.

b) Non-muscle-invasive

Making up the majority of cases, non-muscle-invasive bladder cancers have grown beyond the surface but have not yet spread into the muscle layer of the bladder wall itself.

However, the cancerous cells have infiltrated past the inner lining.

c) Muscle-invasive

In this more advanced stage, the tumor has grown through the lining and into the bladder wall muscle. It may also have spread into the fatty layers or tissues of organs outside of the bladder.

Recognizing the Symptoms of Bladder Cancer

Here are some symptoms to help determine whether you have been diagnosed with bladder cancer:

• Blood in the urine (hematuria)
  • The most common symptom of bladder cancer.
  • Around 80-90% of bladder cancer patients experience this symptom.
  • May present as visible blood that discolors the urine or microscopic amounts detectable only through a urinalysis test.
• Pain or burning during urination (dysuria)
• Increased frequency and urgency of urination
• Difficulty initiating or maintaining a steady urine stream
• Persistent urinary tract infections or bladder irritation
• Loss of appetite and weight loss
• Lower back pain on one side
• Fatigue or weakness

In some cases, patients with more advanced bladder cancer that has spread may experience pelvic or bone pain, swelling in the lower extremities, flank pain, or even a palpable abdominal mass upon physical exam.

If you are experiencing any persistent or recurring urinary symptoms, consult your healthcare provider for proper evaluation and diagnosis.

Unraveling the Risk Factors of Bladder Cancer

Whilst the exact cause of bladder cancer is not fully understood, researchers have identified a few factors that may heighten an individual's risk of developing this disease:

1. Age

The risk of bladder cancer escalates with age, with most cases occurring in individuals over 70 years old.

2.  Gender

Males are 4 times more likely to develop bladder cancer than females.

3. Family History

Having blood relatives diagnosed with bladder cancer indicates a possible genetic predisposition.

4. Smoking

Cigarette smoking is the greatest risk factor, accounting for over 50% of cases. The risk increases with heavier, long-term smoking.

Pipe, cigar, and secondhand smoke exposure also elevates the risk.

5. Occupational Exposures

People who have regular contact with leather, paint, hair dye, as well as aniline dye used in textile and rubber industries, may have higher rates of getting bladder cancer due to regular contact with carcinogenic chemicals.

6. Radiation and Chemotherapy

Previous radiation treatment or use of certain chemotherapy drugs for other cancers can increase bladder cancer risk.

7. Chronic Bladder Inflammation

Recurrent bladder infections, bladder stones, and long-term usage of urinary catheters leading to chronic irritation are linked to a higher incidence of bladder cancer.

8. Other Factors

High consumption of saturated fats, specific herbs, analgesic painkillers, and infection with certain parasites may also contribute to the development of bladder cancer.

Diagnosis of Bladder Cancer

If bladder cancer is suspected, doctors will conduct a number of tests to confirm the diagnosis and determine the extent of the disease.

The diagnostic process of bladder cancer typically involves:

1. Urine Studies

• Urinalysis: Check the appearance, content and concentration of urine
• Urine cytology: Screen urine under a microscope for cancer cells
• Urine culture test: Check for microorganisms that cause infections
• Urinary tumor marker tests: Determine cellular characteristics and markers released by bladder cancer cells into the urine

2. Cystoscopy

This is a primary diagnostic procedure in which a cystoscope (a pencil-sized lighted scope) is inserted through the urethra to view the inside of the bladder and urethra.

This allows the doctor to inspect for tumors or other abnormalities and take biopsy samples if needed.

If the tests above yield a positive result for bladder cancer, you may be required to undergo additional tests to understand the condition further, including:

3. Transurethral Resection of Bladder Tumor (TURBT)

This operation removes small bladder tumors for additional tests. TURBT procedures may also be a treatment, as it eliminates tumors from your bladder before they invade your bladder’s muscle wall.

4. Imaging Tests

• Computed Tomography (CT) scan: Check if cancer has spread into surrounding tissues/organs
• Magnetic Resonance Imaging (MRI) test: Get detailed images of your bladder
• Chest X-ray and bone scan: Check for the spread of cancer cells to lungs and bones
  
  

How to Treat Bladder Cancer?

Several different treatment modalities are used for bladder cancer, depending on the stage and characteristics of the tumor. The treatment may involve one method or a combination approach.

For bladder cancer in its early stages, the treatment options include:

1. Chemotherapy

Chemotherapy utilizes powerful chemicals to kill cancer cells in your body.

For early-stage cases, chemotherapy drugs can be delivered directly into the bladder through a catheter. This intravesical approach targets cancer cells in the bladder without damaging other healthy tissues.

2. Transurethral resection of bladder tumor (TURBT)

This procedure removes early-stage, noninvasive tumors from your bladder.

For bladder cancer in its advanced stages, the treatment options include:

1.Chemotherapy

In this stage, chemotherapy drugs are given orally or intravenously to circulate throughout the body via the bloodstream.

This systemic approach helps the medications reach and destroy cancer cells that may have spread beyond the bladder region. It is often used in combination with other treatments, such as surgery or radiation.

2. Immunotherapy

This treatment triggers your immune response to attack cancer cells. There are different types of immunotherapy:

a) Bacillus Calmette-Guérin (BCG): This is a vaccine that stimulates your immune system against the bladder cancer cells
b) PD-1 and PD-L1 inhibitor therapy: This treatment allows your immune system to recognize bladder cancer cells and attack them


3. Radiation Therapy / Radiotherapy

In this approach, high-energy radiation is used to destroy cancer cells in the bladder region.

It can be used as an alternative to bladder removal surgery in some cases or combined with chemotherapy and TURBT.

4. Targeted Therapy

Targeted therapy attacks the mutated proteins in bladder cancer cells while sparing most healthy cells.

5. Radical Cystectomy

More advanced cases may require a radical cystectomy - surgical removal of the entire bladder, surrounding lymph nodes, and other neighboring organs that have become cancerous.

After cystectomy, urinary diversion will be done to reroute urine out of the body.

Navigating these bladder cancer treatment options can be overwhelming, but you don't have to go through it alone.

Living with Bladder Cancer

Being diagnosed with bladder cancer can be overwhelming, but there are steps you can take to cope and maintain your quality of life throughout treatment and beyond.

1. Follow a Healthy Lifestyle

Eating a balanced, nutrient-rich diet focusing on lean proteins, fruits, vegetables, whole grains and high-fiber foods can aid in recovery and manage treatment side effects like digestive issues.

Regular gentle exercise, as tolerated, may also help reduce stress and boost your overall well-being.

2. Seek Support

Don't go it alone. Lean on your loved ones or connect with others who understand what you're going through in a bladder cancer support group to obtain emotional support and coping strategies.

3. Manage Physical Changes

Depending on your treatment, you may need to adapt to changes in how you pass urine. This could involve caring for a urostomy bag, internal urine pouch or neobladder (new bladder).

Ask your care team for guidance on properly managing these new circumstances.

4. Address Intimacy Concerns

Bladder cancer and its treatments can impact sexual health and intimacy.

Being open with your partner, using vaginal dilators, seeking counseling and exploring other ways to be intimate can help you navigate these changes.

5. Stick to Follow-Up Care

With bladder cancer's high recurrence rates, it's crucial to diligently follow your monitoring and surveillance schedule for the rest of your life.

Routine cystoscopies, imaging and other tests ensure any new tumors are caught early.

Measures for Preventing Bladder Cancer

While bladder cancer cannot always be prevented, being aware of the risk factors and taking proactive steps may help reduce your chances of developing this disease:

1. Avoid Smoking

Cigarette smoking is the greatest risk factor for bladder cancer, more than doubling the risk.

Avoiding smoking cigarettes, pipes, cigars, and secondhand smoke exposure can significantly reduce your risk.

2. Limit Exposure to Chemicals

Certain occupational exposures to chemicals used in dyes, rubber, leather, textiles, paints, and some hair-dressing supplies have been linked to increased bladder cancer risk.

Following proper safety protocols and limiting contact with these substances as much as possible is advisable.

3. Manage Chronic Bladder Issues

Having frequent urinary tract infections, bladder stones, or other chronic bladder inflammation appears to raise the risk of bladder cancer.

Promptly treating these conditions may help reduce risk.

4. Avoid Certain Cancer Treatments (When Possible)

Previous radiation therapy, especially to the pelvic region, and some chemotherapy drugs have been associated with higher rates of subsequent bladder cancer.

Discussing risks and benefits carefully with your doctor is vital.
