How Immunotherapy Works
Immunotherapy is a new way to fight cancer. It uses the body’s immune system to attack cancer cells. This method makes the immune system better at finding and killing cancer cells.
Immune System Mechanism
Immunotherapy works by making the immune system target cancer. T-cells can be trained to find and destroy cancer cells. There are special ways to help them do this better.
Checkpoint inhibitors remove the brakes on T-cells. This lets them fight cancer more effectively. CAR T-cell therapy changes T-cells so they can find cancer cells better.
Types of Immunotherapy Used in Cancer Treatment
There are different kinds of immunotherapy for cancer:
- Monoclonal antibodies: These are proteins made in a lab. They can find and mark cancer cells for the immune system to destroy.
- Cancer vaccines: These vaccines help the immune system fight cancer. They make the immune system respond to cancer cells.
- Immune checkpoint inhibitors: These stop proteins that stop immune cells from attacking cancer. This lets the immune system work better.
Benefits of Immunotherapy
Immunotherapy is precise in targeting cancer cells. This means it can have fewer side effects than other treatments. It can also keep cancer in check for some patients even after treatment stops.
This makes immunotherapy a hopeful treatment for cancer. It offers better chances of recovery for many patients.
