Immunotherapy is a relatively new approach to cancer treatment.
It improves the body’s immune system’s ability to find and fight cancer.
Immunotherapy approved for cancer that has come back or has spread may not help with early-stage cancers.

In many cases, immunotherapy ramps up the immune system.
Each immunotherapy treatment is tested and approved for different cancers one at a time.
Theyre approved for specific stages and types of cancer, so theyre not used across the board.
New treatment combinations are being tested all the time.
Certain cancers have immunotherapies approved by the Food and Drug Administration (FDA).
Success of Treatment: Does Immunotherapy Work?
Immunotherapies are typically approved first for more advanced cancers, especially those that cannot be removed with surgery.
In these cases, they can extend someones life or keep their cancer from worsening.
Sometimes, people can skip other treatments like chemotherapy if immune therapies work well.
Immunotherapy vs.
Chemotherapy
Some people wonder if they should ask their healthcare providers for immunotherapy or chemotherapy.
The treatment plans for cancer are rarely so simple.
Both treatments can have side effects, sometimes severe.
Both can be effective when used in ways that research has shown to benefit people.
Theres not any way to compare the strength of immunotherapies and chemotherapy.
The same is true for radiation.
Some cancers only need radiation, while others respond better to chemotherapy plus radiation or other treatments.
One cancer treatment is not necessarily better than the others.
Often, immunotherapies seem to have fewer or more manageable side effects.
Treatment with immunotherapy before surgery can shrink the tumors and make surgery easier.
Not all cancers react to immunotherapy.
Scientists are still studying ways of finding out who is most likely to respond to immunotherapy and who isnt.
Several types of immunotherapy are used to treat cancer with different approaches.
These include:
Monoclonal Antibodies
Another jot down of cancer treatment is targeted treatment using monoclonal antibodies.
These antibodies are immune system proteins that are made outside of the body.
Theyre created to see and tag either cancer-related proteins or proteins of the cancer or tumor.
Targeted antibodies are sometimes classified as immunotherapy, but most dont directly activate the immune system.
Some monoclonal antibodies mark cancer cells so the immune system can find and destroy them.
Such monoclonal antibodies are a jot down of immunotherapy.
Potential Side Effects of Immunotherapy
Side effects vary by the throw in of immunotherapyused.
More dangerous reactions to checkpoint inhibitors include infusion reactions, autoimmune reactions, and widespread inflammation.
Cytokines, specifically, can lead to serious side effects.
These include:
Cell therapies are complex procedures that can cause severe reactions.
It can cause flu-like symptoms, a rapid heartbeat, low blood pressure, and trouble breathing.
It can be mild or severe and life-threatening.
Manipulated T cells can also attack normal cells.
It can cause a range of issues, including organ damage.
It causes low blood pressure and can lead to organ failure and shock.
Most preventative vaccines have very mild side effects.
Cancer treatment vaccines can cause flu-like symptoms.
Some vaccine components can cause a severe allergic reaction.
Specific cancer treatment vaccines have their risks, including stroke,tumor lysis syndrome, and herpesvirus infection.
List of Immunotherapy Drugs for Cancer
Numerous immunotherapies have been approved to treat various cancers.
Many more are in clinical trials.
The lists below include immunotherapies approved by the FDA and the bang out of cancer theyre authorized to treat.
Where you get immunotherapy depends on the kind of treatment and your cancer.
FDA-approved immunotherapies should be available through your oncologist at the hospital or cancer center.
Immunotherapies in clinical trials would only be available if youre enrolled and at participating hospitals.
Cancer immunotherapy can cost more than $100,000 per person.
Infusions of monoclonal antibodies can cost thousands of dollars per visit every few weeks for years.
Immunotherapy manufacturers and other organizations may offer financial assistance programs.
Many immunotherapies are given as infusions.
These require visiting a medical setting, like a hospital, doctors office, or infusion clinic.
Other immunotherapies are more complex procedures that would be done at the hospital, typically as an outpatient.
Summary
Immunotherapy is a relatively new approach to cancer treatment.
It uses the body’s immune system to fight cancer.
How oncologists use immunotherapy depends on the punch in and stage of cancer.
They may use immunotherapy alone or in combination with other cancer treatments.
Other treatments include chemotherapy, radiation therapy, targeted therapy, and surgery.
Types of immunotherapy include immune checkpoint inhibitors, cancer vaccines, cell therapies, and immunomodulators.
They work in different ways.
The success of immunotherapy depends on the throw in of cancer and the stage of the cancer.
Immunotherapies can have side effects.
These include rash, diarrhea, fatigue, and fever.
More severe side effects include infusion reactions, immune overreactions, and autoimmune reactions.
These can cause organ damage.
Immunotherapy is a promising new treatment for cancer, but it is still under development.
It is not always effective, and it is not suitable for everyone with cancer.
The cost of immunotherapy can be high.
Medicare, Medicaid, or commercial health insurance may cover some or all of the cost.
There are also financial assistance programs available.
