Urinary Bladder Cancer

Bladder cancer: what is it?

Bladder cancer is a quite uncommon kind of cancer that begins in the bladder’s lining. Urine is stored in your bladder, a tiny, hollow organ. Surgery to remove bladder cancer is one of the various treatment options available to medical professionals. Those who have bladder cancer should be careful to follow up with their healthcare professionals since bladder cancer may return after therapy.

Although early-stage bladder cancer, which is cancer discovered and treated before it spreads, may be treated by medical professionals, around 75% of these cases recur.

What physical effects does this disease have on me?

Located between your hip bones, above your urethra, and under your kidneys, the bladder is a triangle-shaped organ. Your bladder, coated with tissue known as urothelium, receives urine from your kidneys. Cells that make up the urothelium expand as your bladder fills with urine and contract when it is empty. (You can hold around two cups of urine in your bladder.)

Bladder cancer develops when certain cells in the tissue lining your bladder get mutations or changes, turning into aberrant cells that proliferate and develop into bladder tumors. If left untreated, bladder cancer may spread to neighboring lymph nodes and eventually to other parts of your body, such as your liver, lungs, or bones.

Which forms of bladder cancer exist?

Bladder cancer comes in a variety of forms. The cells lining the bladder wall where the cancer first began are the names given to each kind. Types of bladder cancer include:

• Transitional cell carcinoma: This kind of cancer begins in the inner lining of your bladder wall’s transitional cells. Transitional bladder malignancies account for around 90% of all cases. This kind of cancer occurs when aberrant cells go through the bladder wall into the fatty tissues that surround the bladder or from the inner lining to other layers deep inside the bladder. Urothelial bladder cancer is another name for this form of bladder cancer.
• Squamous cell carcinoma: The thin, flat cells lining the interior of your bladder are called squamous cells. This kind of bladder cancer, which makes up about 5% of all bladder malignancies, usually appears in persons who have had prolonged bladder irritation or inflammation.
• Adenocarcinoma : Cancers in the glands lining your organs, including your bladder, are known as adenocarcinomas. At 1% to 2% of all bladder cancers, this is an extremely uncommon form of the disease.
• Sarcoma: In rare cases, bladder muscle cells are the initial site of soft tissue sarcomas.

Bladder cancer may also be classified by medical professionals as muscle-invasive, noninvasive, or noninvasive.

• Noninvasive: This kind of bladder cancer may simply affect the surface of your bladder or it can be tumors in a tiny area of tissue. Bladder cancer that has progressed further into the bladder without spreading to the muscles is referred to as non-muscle-invasive.
• Muscle-invasive: This kind of bladder cancer has progressed into the muscles of the bladder wall and may have reached the tissues or fatty layers of organs that are not part of the bladder.

What is the prevalence of bladder cancer?

The fourth most frequent malignancy in men is bladder cancer. Bladder cancer is four times as common in males than in women. However, since they are unaware of the signs, women who do have bladder cancer usually have advanced stages of the illness. People of age 55 years and older are usually affected with bladder cancer. The average age at which bladder cancer is diagnosed is 73 years. 

Causes and Symptoms

What is the typical first sign of bladder cancer?

The most prevalent sign of bladder cancer is blood in the urine. However, blood in your urine alone does not always indicate bladder cancer. This problem is also caused by other situations. However, if you see blood in your urine, you should call a doctor. Additional signs of bladder cancer include:

• Hematuria, or visible blood in the urine: When doing a urinalysis, medical professionals may potentially detect trace quantities of blood in urine.
• Dysuria, or pain during urinating, is a burning or stinging feeling that may occur either before or after urinating. Men may have penile discomfort either before or after urination.
• Frequency of urine : Urinating often indicates that you need to urinate frequently throughout the course of a 24-hour period.
• Difficulty in voiding : Having problems urinating. Your urine may not flow as strongly as normal or it may start and stop.
• Chronic bladder infections: Symptoms of bladder cancer and bladder infections are similar. If your bladder infection doesn’t go away after taking antibiotics, get in touch with your doctor.

Why does bladder cancer occur?

Researchers and medical professionals are unsure of the precise cause of certain bladder cells’ mutations that result in cancer. Numerous risk factors have been shown to raise the probability of getting bladder cancer, including

• Smoke from cigarettes: Your risk of bladder cancer more than doubles if you smoke cigarettes. Additionally, secondhand smoke exposure and pipe and cigar smoking may raise your risk.
• Radiation exposure: Receiving radiation treatment for cancer may make you more susceptible to bladder cancer.
• Chemotherapy: Some chemotherapy medications may make you more vulnerable.
• Exposure to certain chemicals: Research indicates that workers may be at higher risk if they handle specific chemicals found in paint, leather, rubber, dyes, some fabrics, and haircare products.
• Regular bladder infections: Squamous cell carcinoma may be more common in those who often have bladder infections, bladder stones, or other urinary tract infections.
• Chronic catheter use: Individuals who need a bladder catheter on a regular basis may be susceptible to squamous cell carcinoma.

Testing and Diagnosis

How is bladder cancer diagnosed by medical professionals?

To detect bladder cancer, medical professionals do a number of tests, such as:

• Urinalysis: A range of tests are used by providers to examine your urine. To rule out infection in this situation, they could do a urinalysis.
• Cytology: Medical professionals look for indications of cancer by examining cells under a microscope.
• Cystoscopy : The main test for detecting and diagnosing bladder cancer is a cystoscopy. For this exam, medical professionals inspect the interior of your bladder and urethra using a cystoscope, a pencil-sized, illuminated tube. To make it easier to spot bladder cancer, they could employ a fluorescent dye and a unique blue light. While doing cystoscopies, healthcare professionals may also collect tissue samples.

Healthcare professionals do tests to find out more about bladder cancer if urine, cytology, and cystoscopy findings indicate that you have it. These tests include:

• TURBT – In order to remove bladder tumors for further testing, providers perform transurethral resection of bladder tumors, or TURBT. By eliminating bladder tumors before they have a chance to spread to the muscular wall of your bladder, TURBT operations may also be a therapy option. This examination is performed as an outpatient procedure while under general or spinal anesthesia

• MRI – The magnetic resonance imaging (MRI) exam creates fine-grained pictures of your bladder using a computer, radio waves, and a magnet.
• CT scan – A computed tomography (CT) scan is a test that medical professionals may use to determine if cancer has spread beyond your bladder.
• Chest X-ray: This examination allows medical professionals to look for indications that bladder cancer has migrated to your lungs.
• Bone scan : Similar to an X-ray of the chest, a bone scan. Look for indications that your bones have been affected by bladder cancer.

Following that, medical professionals stage the cancer using the knowledge they have gained. Cancer staging aids in treatment planning and the development of a possible prognosis or anticipated result.

There are two types of bladder cancer: invasive (which penetrates the bladder wall and may spread to surrounding organs or lymph nodes) and early stage (which is limited to the bladder lining).

Stage 1 : From TA (limited to the bladder’s interior lining) to IV (most invasive), there are many phases. The cancer is limited to the bladder lining or the connective tissue immediately underneath it in its initial stages (TA, T1, or CIS), and it has not spread to the bladder’s main muscular wall. 

Stage 2-4 : Invasive cancer is indicated by stages II to IV. Cancer in Stage II has progressed to the bladder’s muscular wall. The cancer has progressed to the fatty tissue outside of your bladder muscle when it is at Stage III. When a bladder cancer reaches Stage IV, it has spread to other organs, bones, or lymph nodes.

• TNM, which stands for tumor, node involvement, and metastases, is a more advanced and favored staging approach. Within this system: T2 (the tumor spreads to your major muscle wall underneath the lining) and T4 (the tumor extends beyond your bladder to neighboring organs or your pelvic side wall) are the two types of invasive bladder tumors.
• N0 (no lymph node cancer) and N3 (many lymph nodes or one or more big lymph nodes greater than 5 cm) are the ranges of lymph node involvement.
• M0 indicates that there is no dissemination, or metastasis, outside of your pelvis. M1 indicates that it has spread beyond your pelvis.

Handling and Therapy

How is bladder cancer treated by medical professionals?

Treatment options for bladder cancer are fourfold. Providers are free to mix therapies and utilize any or all of these.

Operation

• TURBT : One typical therapy for bladder cancer is surgery. Depending on the stage of the malignancy, providers choose surgical procedures. For instance, bladder cancer that hasn’t spread may often be treated with TURBT, the operation used to identify the disease. In a procedure called fulguration, medical professionals can remove the tumor or burn it away with high-energy electricity.
• Radical cystectomy : Another course of therapy is a radical cystectomy. Your bladder and associated organs are removed during this procedure. It is performed on patients who have several early-stage malignancies throughout their bladder or cancer that has migrated outside of it. Prostates and seminal vesicles are removed during this procedure in males. Providers may remove a woman’s uterus, ovaries, and a portion of her vagina. Urinary diversion surgery is another procedure that providers use to allow you to continue passing urine.

In order to eradicate any cancer cells that surgery may have overlooked, doctors may provide chemotherapy or radiation treatment after surgery. Adjuvant treatment is what this is.

• Chemotherapy

These are medications that destroy cancer. By inserting a catheter into your urethra, providers may use intravesical treatment to provide chemotherapy medications straight to your bladder. Cancer is targeted via intravenous treatment without causing harm to good tissue.

• Immunotherapy

Immunotherapy targets cancer cells by using your immune system. To treat bladder cancer, your doctor may suggest immunotherapies that include PD-1 or PD-L1 inhibitors or Bacillus Calmette-Guérin (BCG).

• Radiation treatment

An alternative to surgery might be radiation treatment. Medical professionals may mix chemotherapy, TURBT, and radiation treatment. Surgery to remove the bladder may be substituted with this therapy. Before suggesting this therapy, medical professionals take into account variables including tumor development and features.

• Targeted treatment

The genetic alterations that cause healthy cells to become cancerous are the focus of targeted treatment. For instance, medications known as FGFR gene inhibitors target cells that have altered genes that support the growth of cancer cells.
