What is the role of the immune system in cancer?

Cancer occurs when cells in the body grow abnormally and divide uncontrollably, and some cancers may eventually spread into other tissues.4

The main tasks of the body’s immune system are:3

Neutralizing pathogens that have entered the body and removing them;
Recognizing and neutralizing harmful substances from the environment;
Fighting against the body’s own cells that have changed due to an illness, for example cancerous cells.
