How KEYTRUDA works
KEYTRUDA is known as immuno-oncology (or immunotherapy) because it works with the body’s immune system to help find and destroy cancer cells.
KEYTRUDA helps the immune system do what it is designed to do - help to detect and fight disease. KEYTRUDA is not a chemotherapy. Chemotherapy involves the use of medicines to kill or slow the growth of cancer cells.
How KEYTRUDA works with your immune system
The immune system is the body’s natural defence against disease. It sends types of cells called T cells through the body to find and fight infections and diseases - including cancers.
Some cancer cells grow by hiding from the immune system. Immuno-oncology drugs like KEYTRUDA work with the immune system to help find and fight certain cancer cells.
The immune system finds and fights cancer cells as they grow, before they form tumours.
The immune system destroys some cancer cells, but other cancer cells may hide from the immune system. These hiding cancer cells can then grow into tumours.
KEYTRUDA helps the immune system find and treat cancer cells.
