IMMUNOTHERAPY

WHAT IS IMMUNOTHERAPY?

Immunotherapy is a type of cancer treatment that helps the immune system fight cancer. Immunotherapy is a type of biological therapy that uses substances made from living organisms to treat cancer.

The immune system keeps track of all of the substances normally found in the body. Any new substance that the immune system doesn’t recognize raises an alarm, causing the immune system to attack it. For example, germs contain substances such as certain proteins that are not normally found in the human body. The immune system sees these as “foreign substances” and thus attacks them. The immune response can destroy anything containing the foreign substance, such as germs or cancer cells.

IMMUNOTHERAPY CAN BE DONE IN A COUPLE OF WAYS

HOW IMMUNOTHERAPY IS USED TO TREAT CANCER?

Immunotherapy treatments can be used alone or combined with other cancer treatments. There are limits on the immune system’s ability to fight cancer on its own, because many people with healthy immune systems still develop cancer

Sometimes the immune system doesn’t see the cancer cells as foreign because the cells aren’t different enough from normal cells.
Sometimes the immune system recognizes the cancer cells, but the response might not be strong enough to destroy the cancer.
Cancer cells themselves can also give off substances that keep the immune system from finding and attacking them.

Different types of immunotherapy work in different ways. Some immunotherapy treatments help the immune system stop or slow the growth of cancer cells. Others help the immune system destroy cancer cells or stop the cancer from spreading to other parts of the body. Including
