Chemotherapy, immunotherapy, and targeted therapy are different types of cancer treatment. The right option depends on factors such as the type and stage of cancer, biomarker or molecular test results, overall health, previous treatments, and the goals of treatment. In some cases, two or more treatments may be used together.

If you or a loved one has recently been diagnosed with cancer, understanding these treatment options can make discussions with your oncologist easier.

What Is Chemotherapy?

Chemotherapy uses medicines to kill cancer cells or stop them from growing. Because many chemotherapy medicines act on rapidly dividing cells, they can also affect some healthy cells, which may lead to side effects.

Chemotherapy may be used:

• Before surgery or radiation therapy
• After surgery
• For cancers that have spread
• To control cancer growth
• To relieve symptoms caused by cancer

The type, dose, and schedule of chemotherapy depend on the specific cancer and the individual's treatment plan.

What Is Immunotherapy?

Immunotherapy helps the body's immune system recognize and fight cancer. Different types of immunotherapy work in different ways, including immune checkpoint inhibitors and other immune-based treatments.

Immunotherapy may be used alone or together with chemotherapy, targeted therapy, surgery, or radiation therapy depending on the cancer.

Importantly, immunotherapy is not suitable for every patient or every cancer. The decision may depend on cancer type, stage, biomarkers, previous treatment, and other clinical factors.

What Is Targeted Therapy?

Targeted therapy is designed to act on specific proteins, genes, or other features that help cancer cells grow, divide, or spread. It is an important part of precision or personalized cancer treatment.

Because targeted therapies are designed around specific cancer characteristics, biomarker testing may be needed to determine whether a patient has a target that can be treated with an available therapy.

Targeted therapy may be given alone or combined with chemotherapy, immunotherapy, hormone therapy, or other treatments.

Chemotherapy vs Immunotherapy vs Targeted Therapy: What's the Difference?

These treatments are not necessarily alternatives to one another. A treatment plan may involve a combination of therapies when clinically appropriate.

How Does an Oncologist Decide Which Treatment You Need?

There is no single treatment that is right for every cancer patient.

An oncologist may consider:

• The exact type and subtype of cancer
• Cancer stage and whether it has spread
• Biopsy and pathology findings
• Biomarker or molecular testing
• Previous cancer treatments
• Overall health and other medical conditions
• Potential benefits and side effects
• The goals of treatment

For some cancers, biomarker testing can help identify whether targeted therapy or certain immunotherapies may be appropriate.

Your treatment plan may also change depending on how the cancer responds to treatment.

Can Chemotherapy, Immunotherapy and Targeted Therapy Be Combined?

Yes. Depending on the cancer and clinical situation, different treatments may be used together.

For example, targeted therapy may be combined with chemotherapy or immunotherapy in certain cancers. Immunotherapy may also be used alongside chemotherapy or other treatments.

The combination and sequence are determined by the oncology team based on the individual patient's diagnosis and treatment goals.

Questions to Ask Your Oncologist

Before starting treatment, consider asking:

1. What type and stage of cancer do I have?
2. What is the goal of my treatment?
3. Do I need biomarker or molecular testing?
4. Why are you recommending this treatment?
5. Could I need a combination of treatments?
6. What side effects should I watch for?
7. How will we know whether the treatment is working?
8. Would a second opinion be useful?

Understanding the reason behind a treatment recommendation can help you participate more confidently in your cancer care decisions.

FAQs

Is chemotherapy the same as targeted therapy?

No. Chemotherapy generally acts against rapidly dividing cells, while targeted therapy is designed to act on specific cancer-related targets.

Is immunotherapy better than chemotherapy?

Neither is universally better. The appropriate treatment depends on the cancer type, stage, biomarkers, previous treatment, and individual health factors.

Does targeted therapy require biomarker testing?

Often, yes. Testing may identify specific changes or targets that could make a cancer eligible for a targeted treatment.

Can immunotherapy and chemotherapy be given together?

Yes. For some cancers, immunotherapy may be combined with chemotherapy or other treatments when clinically appropriate.

How do I know which cancer treatment is right for me?

Your oncologist will assess your diagnosis, stage, pathology, biomarkers, previous treatments, overall health, and treatment goals before recommending an approach.
