Cancer treatment has evolved significantly over the last decade. While surgery, chemotherapy, and radiation remain important treatment options, immunotherapy has emerged as one of the most promising advancements in cancer care.
For patients diagnosed with bladder cancer, kidney cancer, or other urological cancers, immunotherapy offers a new approach—one that works by helping the body’s own immune system recognize and attack cancer cells. Today, immunotherapy is available in major cancer centers across Mumbai and is increasingly being incorporated into treatment plans for selected patients.
But what exactly is immunotherapy? Who is it suitable for? And how does it fit into the treatment of urological cancers?
Let’s explore.
Understanding Immunotherapy in Simple Terms
The human immune system is designed to identify and destroy abnormal cells, including cancer cells. However, cancer has a unique ability to hide from the immune system or suppress its response.
Immunotherapy helps overcome this problem by enhancing the body’s natural defenses against cancer. Unlike chemotherapy, which directly attacks cancer cells, immunotherapy stimulates immune cells to recognize and fight tumors more effectively.
This has led to significant improvements in outcomes for many patients with advanced urological cancers.
Which Urological Cancers Can Be Treated with Immunotherapy?
Immunotherapy is now being used in several urological cancers, including:
- Bladder cancer
- Kidney cancer
- Advanced prostate cancer (in select situations)
- Certain recurrent or metastatic urological tumors
However, not every patient requires immunotherapy. The decision depends on the type of cancer, stage, previous treatments, and overall health.

Immunotherapy for Bladder Cancer
Bladder cancer is one of the most successful examples of immunotherapy in urology.
In fact, immunotherapy has been used in bladder cancer for decades through BCG (Bacillus Calmette-Guérin) therapy. BCG is administered directly into the bladder and stimulates the immune system to attack cancer cells. It remains a standard treatment for many non-muscle invasive bladder cancers.
When Is Immunotherapy Used for Bladder Cancer?
Doctors may recommend immunotherapy for:
- High-risk non-muscle invasive bladder cancer
- Recurrent bladder cancer
- Advanced or metastatic bladder cancer
- Patients who cannot undergo certain chemotherapy treatments
Modern immunotherapy drugs called checkpoint inhibitors are also used in advanced bladder cancer to help the immune system recognize and destroy cancer cells.
Immunotherapy for Kidney Cancer
Kidney cancer treatment has changed dramatically due to immunotherapy.
In the past, treatment options for advanced kidney cancer were limited. Today, immunotherapy plays a major role in managing metastatic and advanced kidney cancers.
These therapies work by blocking signals that prevent immune cells from attacking tumors. As a result, the immune system can identify and destroy cancer cells more effectively.
Patients Who May Benefit
Immunotherapy may be recommended when:
- Kidney cancer has spread beyond the kidney
- Surgery alone is not sufficient
- Cancer returns after treatment
- Advanced-stage disease requires systemic treatment
Many patients now receive immunotherapy either alone or in combination with targeted therapy.
How Is Immunotherapy Different from Chemotherapy?
This is one of the most common patient questions.
Chemotherapy
- Directly attacks rapidly dividing cells
- Can affect healthy cells as well
- Often causes hair loss, nausea, and fatigue
Immunotherapy
- Activates the immune system
- Targets cancer more selectively
- May offer longer-lasting responses in some patients
Both treatments remain important, and many patients receive a combination depending on their diagnosis.
Types of Immunotherapy Used in Urological Cancers
BCG Therapy
Used primarily for early-stage bladder cancer.
The treatment is delivered directly into the bladder and stimulates a local immune response against cancer cells. BCG remains one of the most effective bladder-preserving treatments available.
Checkpoint Inhibitors
These drugs help remove the “brakes” that cancer places on the immune system.
They are commonly used in:
- Advanced bladder cancer
- Metastatic kidney cancer
- Certain recurrent cancers
Checkpoint inhibitors have become an important part of modern uro-oncology treatment strategies.
Is Immunotherapy Available in Mumbai?
Yes.
Today, advanced immunotherapy treatments are available in Mumbai at specialized cancer centers and hospitals.
Patients seeking treatment for bladder cancer or kidney cancer can access:
- BCG immunotherapy
- Checkpoint inhibitor therapy
- Combination immunotherapy protocols
- Personalized treatment planning
The choice of treatment depends on the patient’s cancer stage, pathology reports, and overall health status.
What Is the Cost of Immunotherapy?
One of the biggest concerns for patients is cost.
The cost of immunotherapy varies depending on:
- The type of drug used
- Frequency of treatment
- Duration of therapy
- Hospital and infrastructure
- Whether treatment is combined with other therapies
Since treatment plans differ significantly between patients, an individualized consultation is necessary to estimate costs accurately.
Are There Any Side Effects?
Like all cancer treatments, immunotherapy can cause side effects.
However, they are often different from chemotherapy-related side effects.
Common side effects may include:
- Fatigue
- Skin rash
- Fever
- Joint pain
- Loss of appetite
Because immunotherapy activates the immune system, it can occasionally cause inflammation in normal organs such as the lungs, liver, intestines, or thyroid gland. Most side effects can be managed effectively when identified early.
